Pressure Control Valves

Pressure control valves comprise all spring-actuated valves which feature the required specific procedural parameters such as inlet or outlet pressures or differential pressures, flow rates or other setpoints.

1. Pressure Reducing Valves
Pressure reducing valves reduce a high and frequently fluctuating pressure to an adjustable constant pressure downstream of the valve. A spring keeps the valve open and this closes as the outlet pressure rises.

2. Back Pressure Regulators
Backpressure regulators control an adjustable constant pressure upstream of the valve. A spring keeps the valve close. As the inlet pressure rises the valve opens.

3. Pilot-operated Control Valves

4. Safety Valves
Safety valves are the ultimate protection device for tanks and pipelines. They prevent pressure limits being exceeded once all automatic control and monitoring equipment has failed.

5. Vacuum Breakers and Vacuum Control Valves
Vacuum breakers protect vessels and pipelines against vacuum. A vacuum can build up when a system is being drained, when it cools down or when a pump fails. Vacuum control valves are pressure reducing or overflow valves which control pressures below 1 bara.

6. Surge Relief Valves
Surge relief valves are used for the decay of pressure surges and of permanent overpressures within pipeline systems.
