About On/Off Valves

Ultra-Chemical-Resistant Threaded On/Off Valves
The most chemical-resistant threaded valves we offer, these have a PTFE seal and an alloy body that can withstand extremely aggressive and corrosive chemicals, such as methyl ethyl ketone and toluene. They are standard port, so they slightly restrict flow.
Monel valves are more corrosion resistant than Alloy 20 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.
- Valve Type: Ball
- For Use With: Acetone, Air, Carbon Dioxide, Diesel Fuel, Gasoline, Kerosene, Methyl Ethyl Ketone, Nitrogen, Salt Water, Soap Solutions, Sodium Hydroxide, Toluene, Water, Xylene
- Ball Material: Monel
- Seal Material: PTFE Plastic
- Seat Material: PTFE Plastic
On/Off Valves with Yor-Lok Fittings for Chemicals
- Valve Type: Ball
- For Use With: Acetone, Air, Ammonia, Carbon Dioxide, Diesel Fuel, Gasoline, Kerosene
- Ball Material: Monel
- Seal Material: PTFE Plastic
- Seat Material: PTFE Plastic
- Specifications Met: ASME B16.34, ASME B31.3
For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves have a PTFE seal and a corrosion-resistant Monel ball and body that can stand up to aggressive and corrosive chemicals such as acetone. All are standard port, so they slightly restrict flow. A red handle makes them easy to identify.
