Severe-Duty Air-Driven On/Off Valves
 |
Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. They operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). Valves don’t require a minimum pressure drop between the inlet and outlet for operation. All meet ANSI/FCI 70-2 Class IV for tight shutoff and have a leakage rate of less than 0.01%.
All valves have a single-acting actuator that only requires air pressure to actuate the valve; they automatically return to the valve starting position when the air turns off. The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. These valves are fail closed unless actuated.
316 Stainless Steel Body—316 stainless steel valves are more corrosion resistant than bronze valves.
Flow Coefficient (Cv)—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.

Flow Coefficient (Cv)—Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

Severe-Duty Air-Driven On/Off Valves for Chemicals

Also known as diaphragm valves, these have a PTFE body and seals that stand up to harsh acidic solutions. The diaphragm can handle dirty liquid, slurries, and abrasive media without damage. All valves operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) 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 have a single-acting actuator that only requires air pressure to open the valve; they automatically spring closed when the air turns off. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Valves are fail closed unless actuated.

Compact Severe-Duty Air-Driven On/Off Valves
 |
Less than half the height of standard severe-duty valves, these fit in small spaces and low-clearance pipelines. They have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. All operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). Valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure.
All valves have a single-acting actuator that only requires air pressure to actuate the valve; they automatically return to the valve starting position when the air turns off. The actuator is directly mounted to the valve body to minimize movement and reduce wear.
Fail-Closed Valve—Fail closed valves are closed unless actuated.
Fail-Open Valve—Fail open valves are open unless actuated.
