Stainless Steel Safety Valve
Stainless Steel Safety Valve; body, seat, disc, spring, stem and lever all manufactured from stainless steel threaded safety valve. Safety valve is a security fitting that automatically opens when the protected system pressure exceeds the set adjustment value, relieving excess pressure, and closes again when pressure returns to normal; it protects boilers, water heaters, compressors and pressurised vessels against damage and accidents from excessive pressure. Its stainless construction ensures hygienic and long-lasting operation in corrosive environments, food, pharmaceutical and clean steam applications.
Standard models are available in 1/2″–2″ sizes, PN25 pressure class, 2–10.5 bar and 10.5–20 bar adjustment ranges and operate between -20 °C and +185 °C. Proportional lift models for liquids and full-lift models for steam and gases in stainless steel; nipple or socket inlet-outlet options are also offered in PN40–PN100 pressure classes.
