Ble ed Valves and Purge Valves
Products Description:
Ble ed valves
Ble ed valves can be used on instrument devices such as multi-valve manifolds or gauge valves to vent signal line pressure to atmosphere before removal of an instrument or to assist in calibration.
Features
Maximum working pressure up to 10 000 psig (689 bar)
Working temperature from -65℉ to 850℉ (-53℃ to 454℃)
Compact design for easy installation
Back stop screw prevents accidental stem disassembly
Vent tube directs excess liquid or gas from system lines
316 stainless steel and alloy-405 material
Variety of end connections
Standard Materials of Construction

Caution
These ble ed valves don't have a cap thread seal, so open the valve slowly and direct the vent hole away from the operator. These valves contain no packing, so some fluid weepage will occur when the valves are opened.
Purge Valves
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.
Features
Maximum working pressure: 4000 psig (276 bar)
Working temperature: -65℉ to 600℉ (-53℃ to 315℃)
Compact design for easy installation
Bonnet crimped to valve body to prevent accidental disassembly
