FireChek® Series
Heat Activated Pneumatic Shutoff Valves

FM approved FireChek® thermal exhaust valve blocks air supply and opens actuator exhaust port allowing valve to close when heat is detected. The FireChek® is resettable and field testable. When the thermal shutoff senses temperatures above the shape memory alloy's actuation level, the shape memory element simultaneously vents pneumatic actuator air pressure and closes upstream supply pressure. A manual reset allows routine performance testing for safety maintenance programs.

• Actuation Temperature: 135°F, 150°F, or 165°F
• Maximum Working Control Pressure: 125 PSIG
• Fill and Discharge Capacity: 1 liter of air in under 1 second at 125 PSIG
• Cv : 0.49
• Overall Dimensions:
  • Length = 2.59"
  • Diameter = 1"
  • Weight = 0.482 lbs.

F Series
Spring Return Pneumatic Actuators

The F Series pneumatic actuators offer a simple and cost effective solution for use on quarter turn (90 degree) ball valves. On ESD series valve assemblies the actuator is operated by an explosion proof solenoid valve.

• Temp Range: -4°F to +175°F
• Supply Pressure:
  • Spring Return: 40 to 120 psi
  • Double Acting: 20 to 120 psi
• Torque Output: up to 40,000 in-lbs.
  (at 80 PSI supply pressure)
  
• Service Life: Up to 1 Million Cycles
• Mounting/Shaft: ISO 5211/Female

E2 Series
Explosion Proof Solenoid Valve

• Brass body construction for general atmospheres; stainless steel for corrosive atmospheres
• Max Air Pressure:
  
  • AC: 150 psi
  • DC: 120 psi
• Externally piloted, loss of electrical power or auxiliary air exhausts air from the actuator and shifts process valve to its fail safe position
