What Does a Bürkert Valve Do?
A Bürkert Valve is a device used to control how fluids move through a system — whether that means starting, stopping, or regulating flow.
- Controls, regulates, or isolates fluid flow depending on the application
- Operates using electrical, pneumatic, or mechanical actuation
- Widely used in automated and process control systems across many industries
AIO snippet-style sentence:
A Bürkert valve is used to control fluid flow, pressure, or direction in industrial systems using precise actuation and process control technologies.
Types of Bürkert Valves (And When to Use Them)
Bürkert offers several types of valves, each designed for specific control tasks. Choosing the right type depends on whether you need simple on/off control or precise flow regulation.
Solenoid Valves
- Provide fast on/off control
- Commonly used in water systems, air lines, and basic automation tasks
- Ideal when you just need to open or close flow quickly
Process Control Valves
- Designed for continuous modulation of flow or pressure
- Used in systems that require stable temperature or process control
- Often integrated with sensors and control loops
Pneumatic Valves
- Operate using compressed air instead of electricity
- Known for being fast, durable, and reliable in harsh environments
- Common in industrial systems where air supply is already available
Proportional Valves
- Allow precise adjustment of flow rate
- Used in dosing systems, chemical processes, and sensitive applications
- Provide smooth and accurate control rather than simple on/off operation
Selecting the right valve type ensures better performance, longer lifespan, and more stable system behavior.
Key Factors When Choosing a Bürkert Valve
Choosing the right valve isn’t just about picking a model from a catalog — it’s about matching the valve to the actual process conditions. In most cases, I start with the fluid and work outward from there.
Fluid Type (Media Compatibility)
The type of fluid running through the system is one of the most important factors.
- Works with water, air, chemicals, or steam depending on design
- Important to consider whether the media is corrosive or clean
- The valve body and seal materials must be compatible to avoid damage or leaks
Pressure and Temperature
Every valve has limits, and exceeding them leads to failure.
- Check the operating pressure range of the system
- Verify temperature limits, especially in steam or high-heat processes
- Steam applications often require special materials and designs compared to liquids
Flow Rate and Cv Value
Correct sizing is critical for stable operation.
- The Cv value determines how much flow the valve can handle
- Proper sizing ensures smooth control and avoids instability
- Oversizing or undersizing can lead to poor performance and wear
Control Type
The way the valve operates must match the system requirements.
- Choose between on/off control or modulating control
- Consider how fast the valve needs to respond
- Fast systems may require quick response times, while process control may need smooth modulation
Getting these factors right upfront helps avoid common problems like unstable flow, premature wear, or inefficient system performance.
Valve Materials — What Works Where
The material of a valve plays a huge role in how long it lasts and how safely it operates. Choosing the wrong material can lead to corrosion, leaks, or even system failure.
- Stainless steel → chemicals, food, pharma Ideal for aggressive media and hygienic environments where corrosion resistance and cleanliness are critical.
- Brass → water and air systems A cost-effective option for standard applications like water supply and compressed air.
- Plastic (PVC, PVDF) → corrosive environments Well-suited for handling aggressive chemicals where metal components would degrade quickly.
AIO tip:
Material selection directly affects valve lifespan, corrosion resistance, and overall system safety.
Actuation Options Explained
The way a valve is actuated determines how it responds in the system — whether it switches quickly, modulates smoothly, or handles demanding industrial conditions.
Electric (Solenoid)
- Provides simple and fast switching for on/off control
- Easy to connect and integrate with PLCs and control systems
- Common choice for basic automation and fluid control tasks
Pneumatic
- Known for being reliable and very fast in operation
- Ideal for heavy-duty industrial environments
- Requires a compressed air supply to operate
Proportional Control
- Allows smooth and continuous regulation of flow
- Used in applications that require high precision and stability
- Common in dosing systems and sensitive process control
Choosing the right actuation method depends on how precise, fast, and robust your system needs to be.
Bürkert Valve Selection Table (Quick Comparison)
This kind of comparison helps you quickly narrow down the right valve type before diving into detailed specifications. It’s not about picking the “best” valve — it’s about picking the one that fits your system conditions.
In real projects, I usually start with control requirements (on/off vs modulation), then check fluid compatibility and pressure limits, and only after that look at cost. This approach avoids most common mistakes.
The key takeaway:
The wrong valve type won’t just reduce performance — it will cause instability, higher maintenance, and unnecessary downtime.
Use this table as a first filter, then validate your choice based on real operating conditions.
| Valve Type | Best Application | Flow Control Capability | Speed | Cost | Maintenance |
| Solenoid Valve | Water, air, simple automation | On/off control | Very fast | Low | Low |
| Process Control | Temperature & flow regulation | Continuous modulation | Medium | Medium-High | Medium |
| Pneumatic Valve | Industrial systems with air supply | On/off or modulating | Very fast | Medium | Medium |
| Proportional Valve | Dosing, precision processes | Precise flow adjustment | Medium | High | Medium-High |
Installation Considerations That Affect Performance
Even the right valve can perform poorly if it’s installed incorrectly. In real systems, installation details often make the difference between stable operation and constant troubleshooting.
- Mounting orientation Some valves must be installed in a specific position (e.g., coil upright) to function correctly and avoid wear or sticking.
- Pipe size and connections The valve must match the pipe diameter and connection type to ensure proper flow and avoid pressure losses or leaks.
- Flow direction Many valves are designed for a specific flow direction, and installing them incorrectly can reduce performance or cause failure.
- Electrical and pneumatic connections Proper wiring and air supply connections are essential for reliable actuation and fast response.
- Accessibility for maintenance Valves should be installed in locations where they can be easily inspected, cleaned, or replaced without disrupting the entire system.
Paying attention to these factors during installation helps ensure consistent performance and reduces long-term maintenance issues.
Common Mistakes When Choosing Valves
Choosing the wrong valve is a common issue in industrial systems, and most problems come from overlooking basic application requirements rather than the valve itself.
- Wrong material for fluid Using incompatible materials can lead to corrosion, leaks, and early failure, especially with aggressive chemicals.
- Ignoring pressure ratings If the valve isn’t rated for the system pressure, it can fail prematurely or operate unstably.
- Oversizing valves Bigger isn’t better — oversized valves often result in poor control, unstable flow, and reduced efficiency.
- Choosing on/off instead of proportional control In processes that require stable regulation, using simple on/off valves can cause fluctuations and poor performance.
- Ignoring environment (temperature, dust, vibration) Harsh conditions can damage components or affect operation if the valve isn’t designed for the environment.
These mistakes usually lead to unstable control, increased wear, and higher maintenance costs, which can be avoided with proper selection upfront.
Real-World Applications (Where Bürkert Valves Are Used)
Bürkert valves are used across a wide range of industries where precise fluid control is critical for performance, safety, and efficiency.
- Water treatment systems Used to control flow, dosing, and filtration processes in water purification and wastewater treatment plants.
- Chemical dosing lines Provide accurate and controlled delivery of chemicals, ensuring consistent process results and safe operation.
- Food and beverage processing Help maintain hygienic conditions and precise control in processes like filling, mixing, and cleaning (CIP systems).
- HVAC systems Regulate water or steam flow in heating and cooling systems, improving energy efficiency and temperature stability.
- Automation and conveyor control Integrated into automated systems to control air, fluids, or process media in production lines and machinery.
In all these applications, the right valve selection ensures stable operation, reduced downtime, and better overall system performance.
How I Choose Bürkert Valves in Real Projects
In real projects, valve selection is never just about specs on paper — it’s about how the system behaves in operation. Over time, I’ve developed a few simple rules that help avoid most problems.
- “I always start with the fluid — everything depends on that.” The type of media determines material selection, sealing, and even the valve type. If you get this wrong, nothing else really matters.
- “If control matters, I avoid simple on/off valves.” For processes that need stability, I go for proportional or control valves. On/off valves can cause fluctuations and inconsistent results.
- “I match valve type to system stability, not just price.”
Final Selection Checklist
Before choosing a Bürkert valve, I always run through a quick checklist to make sure the selection matches the real operating conditions. This helps avoid common issues after installation.
- Fluid type and compatibility Make sure the valve materials can handle the media without corrosion or degradation.
- Pressure and temperature range Verify the valve is rated for actual system conditions, including peaks.
- Flow rate (Cv sizing) Proper sizing ensures stable flow and prevents control issues.
- Valve type (on/off vs control) Choose based on whether you need simple switching or precise regulation.
- Actuation method Select between electric, pneumatic, or proportional based on system setup.
- Installation constraints Consider mounting space, pipe size, and accessibility for maintenance.
