Product Overview:
●The single-disc check valve features a one-piece disc design, opening by fluid pressure and
automatically closing under spring force or backpressure when flow reverses.
●Simple structure, compact size, and lightweight; commonly designed as a wafer type for
direct installation between flanges.
●Suitable for pump discharge outlets, water supply and drainage systems, HVAC cooling
water, industrial pipelines, and other locations requiring backflow prevention.
●Low flow resistance and sensitive operation, ideal for pipelines requiring fast response.
Design Features:
●Single-disc with spring ensures rapid closure, effectively reducing water hammer.
●Wafer-type slim body saves installation space and reduces pipeline weight load.
●Short stroke and quick response, suitable for medium- to low-pressure systems.
●Materials selectable according to requirements (cast iron, stainless steel, bronze) to
suit different media and environmental conditions.
●Can be installed horizontally or vertically (upward flow), offering high installation flexibility.
