Threaded On/Off Valves
Use these valves in general purpose applications such as those with water, oil, air, and inert gas.
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.

Compact Threaded On/Off Valves
Install these valves in tight spots, such as where pipelines are crowded together. They’re less than half as long as standard threaded valves and one-third shorter in height.
Bronze valves are stronger and more durable than brass valves.Screwdriver-operated valves are our most compact option. Since they open and close with a slotted screwdriver (not included), they’re also the most resistant to accidental movement.
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.

Fittings for Natural Gas, Propane, and Butane
- Valve Type: Ball
- For Use With: Butane, Natural Gas, Propane
- Seal Material: PTFE Plastic
- Specifications Met: CSA Certified, CSA-US Certified, UL Listed
With 45° flared tube fittings, these valves form a tight seal on metal tubing lines for natural gas, propane, and butane. All have a T-handle that resists accidental movement when snagged or bumped. Valves 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.

Compact Threaded Check Valves
- For Use With: Air, Nitrogen, Water
- Ball Material: 304 Stainless Steel
- Seal Material: See table
With a shorter end-to-end length than other check valves, these fit in tight spaces. They open to allow flow in one direction and close when flow stops or reverses.
303 stainless steel valves are more corrosion resistant than brass 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.
