Threaded On/Off Valves
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.

- Valve Type: Ball
- For Use With: Argon, Helium, Krypton, Neon, Oil, Steam, Water, Xenon
- Seal Material: PTFE Plastic

Miniature Threaded On/Off Valves
- Valve Type: Ball
- For Use With: Air, Argon, Helium, Krypton, Neon, Water, Xenon
- Seal Material: EPDM Rubber
With 10-32 UNF threads and a body less than 3/4” long, these valves are often used to control flow in miniature pipelines. They have a 303 stainless steel body for good corrosion resistance. 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.

Miniature Threaded On/Off Valves for Chemicals
- Valve Type: Ball
- For Use With: Air, Argon, Butane, Carbon Dioxide, Chlorine, Citric Acid, Diesel Fuel, Ethylene Glycol, Fuel Oil, Gasoline, Helium, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Krypton, Mineral Spirits, Natural Gas, Neon, Nitric Acid, Nitrogen, Oil, Oxygen, Phosphoric Acid, Propane, Salt Water, Soap Solutions, Sodium Hydroxide, Sodium Hypochlorite, Sulfuric Acid, Toluene, Water, Xenon, Xylene
- Ball Material: 316 Stainless Steel
- Seal Material: Fluoroelastomer Rubber
- Seat Material: Fluoroelastomer Rubber
To withstand aggressive and corrosive solutions in miniature chemical-processing pipelines, these tiny valves have a chemical-resistant fluoroelastomer seal and a corrosion-resistant 303 stainless steel body. They 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.

On/Off Valves with 37° Flared Tube Fittings for Fuel
- Valve Type: Ball
- For Use With: Diesel Fuel, Fuel Oil, Gasoline
- Seal Material: PTFE Plastic
These valves have 37° flared tube fittings that form a tight seal on metal tubing lines to transfer diesel fuel, fuel oil, and gasoline. All are full port, so they do not restrict flow.
