Wafer Check Valve

Kelor Valves Single Plate Wafer Check Valve

Kelor Valves’ Single Plate Wafer Check Valve features a short‐pattern, sandwich‐style, flangeless wafer body engineered to API 6D and ASME B16.10 face‐to‐face dimensions. Ideal for pump‐discharge duties, its eccentric hinge‐pin mounting and resilient disc‐seat design ensure a positive shut‐off against backflow. A robust yet simple construction delivers maintenance-free operation, and a spring‐loaded variant is available on request.
