Safety Relief Valves

Cici Boiler Rooms is your one-stop-shop for safety valves! We stock a large inventory of common valves from Kunkle, Watts, and Conbraco. However, we can order any valve that you need.

To assist you in ordering the proper safety relief valve for your application, we recommend that you provide the following information:

  • Service (Air/Gas, Liquid, or Steam)
  • Size of valve inlet
  • Set pressure
  • Capacity

You may also want to consider the following:

  • Brand and model number
  • Body material & valve trim
  • Allowable Overpressure (3% ASME Section I, 10% ASME Section VIII, 25% ASME Section IV)
  • Accessories (such as a gag, screwed cap, etc)
