Disc Check Valves
Disc Check Valve
The disc check valve is a wafer-type body check valve with a spring-loaded disc that closes when flow stops. With its compact mounting length and lightweight design, it is preferred in confined spaces; thanks to the spring, it closes as soon as flow ceases and operates in any position.
Models with brass (MS58) and GG-25 ductile cast iron bodies are rated to 16 bar and 250 °C; models with AISI 304 and AISI 316 stainless steel bodies are rated to 40 bar and 300 °C. Sealing is metal-seated as standard; an O-ring option is available. Available from DN15 to DN250; commonly used in steam, hot water, condensate and process lines.
