Attach gauges or sensors to these valves so you can remove them for maintenance and calibration without depressurizing your line. Also known as block and bleed valves, turn the handles to block both upstream and downstream flow, drain the liquid trapped in the valve through the bleed port, and then remove your instrument from the gauge port. Often used in chemical-processing lines, these valves have a PTFE seal and a corrosion-resistant 316 stainless steel body. All are standard port, so they 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.
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.

Flanged Air-Driven On/Off Valves for Chemicals
- Valve Type: Ball

- Ball Material: 316 Stainless Steel
- Seal Material : PTFE Plastic
- Seat Material: PTFE Plastic
- Actuator Housing Material: Aluminum
- Specifications Met: ASME B16.34
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.
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.

High-Pressure Threaded Precision Flow-Adjustment Valves
Often used in hydraulic and compressed air systems, these valves can withstand at least 6,000 psi. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.
316 stainless steel valves are more corrosion resistant than brass and steel valves.
Metal-to-metal seats resist temperature fluctuations.
Valves with packing have a nut that can be tightened to compress the packing if it leaks.
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.

- Needle Material: 316 Stainless Steel
For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. The 316 stainless steel body, seal and needle, and the PTFE seat and packing can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Threads and a hex nut below the handle allow you to mount these valves in instrument panels. All have a nut that can be tightened to compress the packing if it leaks. Valves have bubble-tight soft seats that provide a tight seal when the valve is completely closed.
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.

Check Valves with Barbed Fittings for Harsh Chemicals
Prevent backflow in chemical tubing lines. These valves have barbed fittings that grip onto tubing, providing a secure hold. The plastic body and fluoroelastomer seal provide excellent chemical resistance. Valves open to allow flow in one direction and close when flow stops or reverses.
Polypropylene valves are more corrosion resistant than nylon valves.
Nylon valves are more impact resistant than polypropylene valves.
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.

- Seal Material: PTFE Plastic
Often used for chemical analysis and other laboratory testing, these valves have a PTFE seal and body to withstand aggressive and corrosive solutions. All operate on electricity to automatically divert flow between ports. They do not require a pressure drop for operation. Any port can be used as an inlet or an outlet. Valves can direct flow from the inlet port to either outlet port. They cannot shut off flow. The actuator is mounted directly to the valve body to minimize movement and reduce wear.
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.
