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.

- Seat Material: PTFE Plastic
- Actuator Housing Material: Plastic
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.

- 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.

On/Off Valve Bodies
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.
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.

Easy-to-Install Threaded Check Valves for Harsh Chemicals
To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings. 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 PVC or CPVC 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.

Vacuum-Breaking Valves for Chemicals
A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals. Also known as vacuum breakers, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.
