Frequently Asked Questions
A single plate (wafer) check valve has one spring-loaded disc that closes quickly against a center-mounted seat, fitting between two pipe flanges (wafer style). Its compact size and fast, spring-assisted closing make it a common choice for pump discharge protection where a swing check valve would be too bulky or slow to close.
A single plate check valve uses one full-diameter disc, while a dual plate (double door) check valve uses two spring-loaded half-discs hinged on a central pin — dual plate designs are generally lighter and close even faster, but single plate designs are simpler and often more economical for smaller sizes.
We supply single plate check valves from 15 NB to 600 NB, Class 150# to Class 600#, in Cast Iron, Carbon Steel, and Stainless Steel.
