The check valve RK44 from GESTRA is a high-grade wafer valve for use in water, steam and condensate systems. With its robust bronze construction, spring-loaded function and compact design it offers maximum operational reliability and a long service life – ideal for industrial applications.
Sizes: DN15-DN200
Dichtungen:
Metallisch (Standard)
EPDM for water/condensate
FPM for gases and air
Special versions:
Without spring for the lowest opening pressures
Special springs for defined opening pressures
The spring determines the opening pressure – from 20 mbar for sensitive circuits up to 1,000 mbar, where reliable closing against backflow counts. Without a spring only vertical installation with upward flow is permitted.
