Detailed Product Description

Safety valves were first used on steam boilers during the industrial revolution. Early boilers without them were prone to accidental explosion when the operator allowed the pressure to become too high.
The valves are factory set, tested, sealed and tagged to service your specific application. Air, Steam, Gas or Liquid.
The set pressure or pop off point are set in accordance to safety and capacity requirements.
We recommend settings to not exceed 10% of the vessels or lines operation pressure.
As required by the ASME all valves manufactured for Steam servicing must have a handle lift lever. For Air and Gas this is optional.  Liquid Valve series has the option of a lever for field adjustments.



Inlet and outlet sizes. Industry standards are Male Inlet and Female outlet. Please specify if otherwise. Space or the valves physical size may also be a consideration.



Refer to each listing for sizes, capacities, set pressure  and applications.
