Steam Safety Valves

We offer a selection of safety valves for use on steam, water, air and other systems from TLV, this includes the SV4411 cast iron and SV4412 cast steel flanged safety valves in sizes up to 2 1/2" (DN65). These valves, in the event of an overpressure event, will automatically open and begin venting to atmosphere and close again when the pressure falls.

The TLV SV4411 comes with PN16 flanged ends to EN 1092-1 as well as a 13 bar pressure rating, SV4412 safety valves are PN40 flanged (PN16 outlet) with a 40 bar pressure rating. All of our steam safety valves come with a stainless steel 316 seat and SS 420 disc.
