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 PEEK 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.

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.

Full-port valves do not 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.

Bolt these valves to ANSI flanges. A glass-filled vinyl ester body and a PTFE seal withstand aggressive and corrosive solutions in chemical-processing applications. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 5/16”. All are standard port, so they slightly restrict flow.

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a PTFE seal and a PVDF body. 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 install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. With a fluoroelastomer seal and a PVDF body, they 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 install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.

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 and seal, the PTFE seat and packing, and the Monel needle 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.

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.

These valves open to allow flow in one direction and close when flow stops or reverses.

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.
