Pilot Operated Pressure Regulators

Well-designed steam systems produce clean, dry steam for delivery at high pressure — the best-quality steam at the lowest cost. Lower-pressure steam is usually needed at the point of use. Effective control demands an automatic valve that can reduce steam pressure accurately, reliably and at a cost to suit the application. Like direct-acting pressure-reducing valves, these valves are self-powered. Pilot operation provides accurate control under large load-change conditions. Available in iron, cast steel and stainless steel in sizes from 1/2″ to 8″.

Spirax Sarco’s SV7 safety valve series guards against excess pressure across a broad spectrum of industrial steam and air applications, including fired and unfired pressure vessels, steam systems, heat exchangers, condensate return systems, boilers, generators, and downstream pressure-reducing valves and air systems.
Constructed of cast iron or cast steel with stainless-steel trim, the valves have a modern design and come in a wide range of inlet sizes and body materials. They are approved by the National Board and conform to Sections I and VIII of the ASME boiler and pressure vessel code.

Inverted bucket traps are the most robust type of the mechanical traps. They can resist water hammers and, with a check valve fitted in the inlet, they can be used with superheated steam. Inverted bucket traps are available with a wide selection of valve orifices for precise pressure and load matching.
