Valve-Flush Mtd 2 Mpt 250 Psi

Flush Mounted Internal Relief Valves Primarily for trucks transporting LP gas, NH3 or other compressed gases. Types H722 and H733 stainless steel relief valves resist rust and corrosion. Stainless steel makes it easy to remove the valve from the tank for periodic testing (as prescribed by DOT), and permits standard tank couplings instead of the more costly flanged tank openings. Field repairable valve seats allow for seat replacement without affecting relief set point. Tight fitting protective caps are standard on the valve to ensure no debris blocks the valve discharge. Standard set points listed with UL and approved by ASME include 125, 156, 250, 265, 275 and 312 PSIG (8,6, 10,8, 17,2, 18,3, 19,0, and 21,5 bar). Special set points are available from 100 to 400 PSIG (6,9 to 27,6 bar) with ASME approvals. The flow area is 1.39 square inches for the H722 and 3.20 square inches for the H732. A 1 1/2" and 2 1/2" hex size wrench can be inserted into the valve socket when installing/removing the valve to provide a means of attaching a standard wrench.
