High-Flow Flanged Air-Driven On/Off Valves
- Valve Type: Ball
- For Use With: Oil, Air, Natural Gas, Propane, Butane, Argon, Diesel Fuel, Ethylene Glycol, Fuel Oil, Gasoline, Helium, Kerosene, Neon, Steam, Xenon, Krypton
- Seal Material : PTFE Plastic
- Specifications Met: ASME B16.34
Their ball-valve design allows these valves to handle three times the flow of other flanged valves. They operate on compressed air to automatically start and stop flow faster actuation than motor-driven valves. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation. All are full port, so they do not restrict flow.
The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied to close them, so they do not have a valve starting position.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

High-Flow Flanged Motor-Driven On/Off Valves
- Valve Type: Ball
- For Use With: Water, Oil, Air, Argon, Helium, Krypton, Neon, Steam, Xenon
- Seal Material : PTFE Plastic
- Specifications Met: ASME B16.34
Their ball-valve design allows these valves to handle at least three times the flow of standard flanged valves. All operate on electricity to automatically start and stop flow. They don’t require a minimum pressure drop between the inlet and outlet for operation. All are fail in place; upon loss of power, the valve will remain in its current position. Valves are full port, so they do not restrict flow.
The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. Two single pole, double throw (SPDT) auxiliary switches allow you to connect these valves to temperature-monitoring equipment, programmable logic controllers, or conveyor sirens. The internal heater automatically turns on when the valve is actuated to prevent motor damage caused by condensation buildup. A manual override allows you to operate the valve during power outages.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
