Use air pressure to automatically control the flow of liquids in sanitary environments, such as food and beverage processing plants. These valves connect to your liquid line with quick-clamp sanitary fittings, also known as tri-clamp connections, which are easier to remove and sanitize than threaded connections. You’ll need a gasket and clamp to connect them to another quick-clamp fitting (not included). They are also self-draining, so liquids drain completely and don’t pool on actuators or valves. The polished interior is extremely smooth, so there’s nowhere for bacteria to hide. Made of stainless steel, these valves won’t corrode from frequent washdowns with harsh cleaners. Their seal is FDA compliant for direct contact with food.

They are single-acting actuators, which open from the force of compressed air and close with an internal spring. You’ll also need either an electric pilot valve or a manual on/off valve (not included) to control the air flowing to the actuator. They open and close faster than motor driven valves and can be operated remotely, so they’re often used in automated liquid lines. Since they are normally closed unless air pressure opens them, these valves will stop the flow if there is a power outage or the air supply is cut. There must be a minimum pressure drop between the inlet and the outlet for these valves to work, meaning that the upstream pressure must be greater than the downstream pressure.

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.

Actuator repair kits include replacements for all parts inside the actuator.
