To create a tight seal in vacuum conditions higher than 29.9” Hg, these valves have ultra-high-vacuum tube fitting connections, which are also known as KF, QF, and NW fittings. They’re often used in applications such as vacuum coating and heat treating, leak testing, and analyzing gases. The three-piece bolted body comes apart for inline replacement of internal components. Body is 316 stainless steel for excellent corrosion resistance. The lockable lever handle can be fixed in place using a padlock (not included). Valves are full port, so they do not restrict flow.

Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems. Valves gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. They connect to another quick-clamp (ISO-KF) fitting with a clamp and a ring (sold separately). All have a nonrising stem that stays in the same position whether the valve is open or closed. Body is 304 stainless steel for good corrosion resistance.

To maintain sanitary standards in food and beverage applications, these valves have sanitary quick-clamp connections and polished internal surfaces for easy cleaning. The three-piece bolted body comes apart for access to internal components without unthreading pipe connections and removing the valve from your line. They have a ball-valve design that provides higher flow rates than other air-driven valves. All 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 an electric pilot valve or a manual on/off valve (not included). These valves do not require a minimum pressure drop between the inlet and the outlet for operation. All are full port, so they do not restrict flow.

Body is 316 stainless steel for excellent corrosion resistance. The actuator is directly mounted to the valve body to minimize movement and reduce wear. 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, 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.

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.

For food and beverage systems that require frequent cleaning, these valves have polished internal surfaces and sanitary quick-clamp connections for easy disassembly. The three-piece bolted body comes apart for access to internal components without unthreading pipe connections and removing the valve from your line. Valves operate on electricity to automatically start and stop flow. They don't require a minimum pressure drop between the inlet and the 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.

Body is 316 stainless steel for excellent corrosion resistance. The actuator is directly mounted to the valve body to minimize movement and reduce wear. 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. The 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.
