Jamesbury Figure 1056 Gas Shutoff & Vent Valve
Brand: MetsoThe JAMESBURY Figure 1056 Automatic Safety Gas Valves are CSA approved for providing protection against fire and explosive hazards during light-off and operation of gas-burning equipment.
When the electrical signal is interrupted or when there is a loss of air pressure, these gas-line valves operate rapidly to isolate or allow gas flow. This action may be initiated either by safety trip or normal shutdown sequencing.
The units consist of a valve with EMISSION-PAK, actuator, limit switch, and solenoid pilot valve, and are approved as an assembly.
Valves are available in ANSI Class 150 flanged design in 3" to 8" (80 to 200 mm) standard-port sizes.
Valves are offered with either carbon steel or 316 stainless steel bodies.
Trim is 316 stainless steel.
