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.
