The Jamesbury Figure 1059 Automatic Safety Gas Valves are Australian Gas Association (AGA) approved for providing protection against fire and explosive hazards during light-off and operation of gas-burning equipment.

When the electrical signal is interrupted, 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 unit consists of a valve with actuator, limit switch, and solenoid valve, and are approved as an assembly.

Flange valves are available in ASME Class 150 and Class 300 1/2" through 6" (DN 15 to 150) standard port and full port sizes.

Screwed end and socket weld valves are available in ASME Class 600 1/2" through 2" (DN 15 to 50) standard port and 1/2" through 1-1/2" (DN 15 to 40) full port.

Valves are offered with either carbon steel or 316 stainless steel bodies.

Trim is 316 stainless steel.
Features
  • Polymeric flexible lip seat design offers tight shut off in either direction and extended cycle life with minimum maintenance
  • Automatic quarter-turn rotation is provided by a choice of spring-diaphragm or spring-return piston actuators
  • 316 stainless-steel valves are available for highly corrosive atmospheres. Actuators are especially well-suited to industrial environments
  • Limit switches are actuated directly from the valve/actuator drive train, reliably communicating a true valve-position
