Purge valves are manual bleed, vent or drain valves. The cap is used to release system pressure. One-quarter turn with a wrench from finger-tight obtains leaktight closure on first makeup. Snugging with a wrench ensures closure to the rated pressure with subsequent makeups.
* Maximum working pressure up to 4000 psig (276 bar)
* Working temperature from -65ºF to 600ºF (-53ºC to 315ºC)
* Compact design for easy installation
* Bonnet criped to valve body to prevent accidental disassembly
* 316 stainless steel and brass material
* Variety of end connections
