With a PVC body and a fluoroelastomer seal that can withstand aggressive and corrosive solutions, these valves are often used in chemical-processing applications. Their ball-valve design provides higher flow rates than other air-driven valves. They operate on compressed air to automatically start and stop flow faster 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. They are full port, so they do not restrict flow.
All have union fittings on each end that separate into multiple pieces for easy installation and removal from your pipeline. Valves come with both threaded NPT fittings and unthreaded socket-connect female fittings.
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. All valves meet NSF/ANSI 61 and NSF/ANSI 372 Standards.
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, 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.

Versa-Mount Air-Driven On/Off Valves for Chemicals
- Valve Type: Piston
- For Use With: Water, Ethylene Glycol, Hydrochloric Acid, Isopropyl Alcohol, Nitric Acid, Salt Water, Sodium Hypochlorite, Citric Acid, Phosphoric Acid, Deionized Water, Ethanol, Methanol, Mineral Spirits, Soap Solutions
- Seal Material : Fluoroelastomer Rubber
With a chemical-resistant fluoroelastomer seal and no metal parts to corrode, these valves are often used in chemical-processing and water-treatment applications. The lightweight actuator and compact body are designed for installation in any mounting orientation. 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. These valves are normally closed unless actuated.
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.
