Seat Leakage Classifications for Sanitary Valves
When selecting or operating sanitary valves, the seat leakage is a very important consideration that you shouldn’t skip. To have a better understanding of this factor, it’s a must to know some relative terms and definitions: Seat Leakage: the quantity of test fluid passing through an assembled valve in the closed position under the test conditions as […]
Read moreWhat Cause The Valve Sealing Surface Damage?
The sealing surface of the regulating valve is one of the most important working surfaces of the valve. Whether the material selection is reasonable and its quality directly affects the function and service life of the sanitary regulating valve. As the use of regulating valve is very wide, the working condition of the sealing surface varies […]

How do pilot-operated relief sanitary relief valves work? The pressure of a pilot-operated sanitary relief valve is provided on the upstream side (the system being protected) at the dome often by a small pilot tube. The downstream side is the pipe or open-air where the PORV directs its exhaust. The outlet pipe is usually larger […]
Read moreCommon Causes of Valve Sealing Failure and Leakage
Sanitary valves are control components that provide diversion, cut-off, throttling, check, diversion or overflow, and pressure relief in pipeline fluid conveyance systems. Valve sealing is a critical factor when safely processing and transporting fluids and gases. Even a small valve seal failure or a slowly dripping valve leak can quickly lead to a catastrophic flood, […]
