High-pressure valve made of chrome steel for steam and aggressive media up to PN40.
The check valve RK76 from GESTRA is the ideal solution for high-pressure and high-temperature applications. With its robust chrome steel construction, spring-loaded function and compact design it offers maximum safety and reliability in power plant, chemical and process plants.
The material of the valve plate decides everything else: metal-seated for steam up to 300 °C, PTFE for aggressive media from -190 °C, EPDM for water and condensate with the best tightness. Two of these requirements cannot be met at the same time.
