What is a hydraulic valve？

Different functions implemented in individual assemblies or function units are needed to ensure safe operation and metering accuracy for a hydraulic diaphragm pump head. Various hydraulic valves as well as diaphragm monitoring are the most important of these to mention.

These are covered below. Hydraulic valves are sometimes referred to by different names from one manufacturer to another, and as a result no standardized names can be found among them. The following selection lists some typical valves, along with their names and design:

– Vent valve/gas removal valve 

– Leak replenishing valve/snifting valve 

– Pressure relief valve 

– Diaphragm monitoring
