Steam safety valve 651mHIK series

for hot waterthreadeddiaphragm

Safety valves with diaphragm made of gunmetal, all-metal construction angle type with threaded connections 651mHIK with inlet and outlet diameter equal Robust safety valve with diaphragm with an all-metal construction. Designed to protect hot-water- and heating-systems. This unmatched design, which does not have any plastic parts, means that these valves are also suitable for very high external temperatures. For the protection of: thermostatically protected closed-circuit water heating systems with flow temperatures of up to 120°C. Not permitted in Germany. Should the thermostatic limiting and control unit fail, the safety valve has to blow-off the total heating output of the boiler as hot water and steam. As these valves are completely made of metal they can also be installed at high environmental or radiation temperatures. heating systems for building technology- and industrial-applications co-generation plants (CHP)
