|25 (1.7)||20 to 30 (1.3 to 2.0)||17 (1.1) or more inlet pressure|
RESEAL PRESSUREThe differential pressure between the outlet and inlet, at which no flow is passing through the valve.
CRACKING PRESSUREThe differential pressure between the outlet and inlet, at which an initial flow is passing through the valve.
|O-Ring Material||Temperature Rating OF(OC)|
|Buna - N||-10 to 250 (-23 to 121)|
|EPDM||-70 to 250 (-55 to 121)|
|Vitonâ (Fluorocarbon)||-10 to 350 (-23 to 191)|
- Standard Test : Each valve is factory tested with nitrogen gas at 1000 psig (69 bar) for leakage at the seat and packing.
- Optional Hydrostatic test : This test is performed with de-ionised water at 1.5 time the working pressure.
