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.

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.

Solenoid Diverting Valves for Chemicals
- For Use With: Acetone, Air, Ammonia, Argon, Chlorine, Citric Acid, Deionized Water, Diesel Fuel, Ethylene Glycol, Fuel Oil, Helium, Hydrochloric Acid, Krypton, Methanol, Neon, Nitric Acid, Oil, Oxygen, Phosphoric Acid, Salt Water, Sulfuric Acid, Water, Xenon, Xylene
- 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.
