High-Pressure Stop Valves
YFSVM series
High-pressure stop-valve families with model-specific body arrangements, connection options and dimension references.
Share your application and required configuration for a project-specific quotation.
Product overview
The YFSVM stop-valve family provides manual isolation within a defined high-pressure circuit. The catalog includes straight, angle and three-way body arrangements, with specifications and dimensions listed by model.
A replacement must match more than the nominal pressure: consider the medium, wetted materials, temperature, port standard, flow path and installation envelope. Send the complete existing model code and connection information so the offered valve can be checked against the actual requirement.

Before you enquire
Can a stop valve be used as a pressure-relief device?+
A stop valve is an isolation component. Pressure-relief requirements must be addressed with the appropriate separately specified equipment.
Is the thread size enough to identify a replacement?+
Also provide the thread standard, pressure/temperature duty, material, body configuration and existing model information.
Can you work from photographs?+
Photographs help identify the item, but dimensions, nameplate information and connection details are needed before confirming a replacement.
