Bolt these valves to ANSI flanges—they meet ASME dimensional standards. They have a plastic body and a seal that withstand aggressive and corrosive solutions in chemical-processing applications.

Glass-filled vinyl ester valves stand up to a wide variety of harsh acids and solvents. You can rely on them for repeated use, changes in pressure and flow rate, and hot and cold conditions.

Valves with a lockable lever handle can be fixed in place with a padlock (not included). They give you more leverage than short lever handles, so you can quickly open and close the valve with minimal effort.

Standard-port valves slightly restrict flow.

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.

For applications sensitive to contamination, these valves stop flow without contacting the process media by pressing down on the outside of tubing. They operate on electricity to automatically start and stop flow.

These valves are normally closed unless actuated. They don’t require a minimum pressure drop between the inlet and outlet for operation. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

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 normally closed unless actuated.

A 316 stainless steel body and a PTFE seal stand up to aggressive and corrosive solutions in chemical-processing applications. Their ball-valve design allows these valves to handle at least three times the flow of standard flanged valves. For faster actuation than motor-driven valves, they operate on compressed air. 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 automatically start and stop flow and don't require a minimum pressure drop between the inlet and outlet for operation.

Valves are full port, so they do not restrict flow. 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. 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 to close them, 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.

For high-flow chemical-processing applications, these valves have a ball-valve design that provides at least three times the flow of standard flanged valves. They have a 316 stainless steel body and a PTFE seal that can stand up to aggressive and corrosive solutions. Valves operate on electricity to automatically start and stop flow. They don’t require a minimum pressure drop between the inlet and outlet for operation. All are fail in place; upon the loss of power, the valve will remain in its current position. Valves are full port, so they do not restrict flow.

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. 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.

Automatically or manually start and stop flow in your line with these valve bodies, which attach to your actuator. They have a full port, so they don’t restrict flow. All meet standard ISO 5211 mounting dimensions. Use valve stem adapters to mount to valve actuators with a larger stem opening.

316 stainless steel valve bodies have excellent corrosion resistance.

Three-piece valve bodies are easy to maintain because you can take them apart without removing them from your line.
