PRODUCT OVERVIEW
Silent Check Valves
Short-stroke, spring-assisted check valves for reduced closing impact.
- Pressure: 1.6 MPa, 2.5 MPa
- Connection type: Wafer
- Size range: DN50–DN500
Product Description
Silent check valves use a spring-assisted, short-stroke disc to respond quickly as forward flow decreases. This design aims to reduce the slam associated with sudden flow reversal and is commonly considered for clean-water pump discharge duties. Spring selection, pressure loss and installation requirements must suit the system.
