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.

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.

Flanged On/Off Valves for Chemicals
- Valve Type: Ball
- For Use With: Citric Acid, Deionized Water, Diesel Fuel, Ethanol, Ethylene Glycol, Fuel Oil, Gasoline, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Methanol, Methyl Ethyl Ketone, Mineral Spirits, Oil, Phosphoric Acid, Salt Water, Soap Solutions, Toluene, Water, Xylene
- Ball Material: Glass-Filled Vinyl Ester
- Seal Material: PTFE Plastic
- Seat Material: PTFE Plastic
- Packing Material: PTFE Plastic
- Specifications Met: ASME B16.10, ASME B16.5
Bolt these valves to ANSI flanges. A glass-filled vinyl ester body and a PTFE seal withstand aggressive and corrosive solutions in chemical-processing applications. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 5/16”. 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.

Easy-Clean Threaded Diverting Valves for Chemicals
- Valve Type: Ball
- For Use With: Air, Ammonia, Butane, Carbon Dioxide, Citric Acid, Deionized Water, Diesel Fuel, Ethanol, Ethylene Glycol, Fuel Oil, Isopropyl Alcohol, Kerosene, Natural Gas, Nitric Acid, Oil, Oxygen, Phosphoric Acid, Propane, Salt Water, Soap Solutions, Sodium Hypochlorite, Sulfuric Acid, Toluene, Water
- Ball Material: Polypropylene Plastic
- Seal Material: Fluoroelastomer Rubber
There’s no need to unbolt these valves for cleaning—remove the handle and slide the valve apart for inline access to internal components. Also known as elliptical valves, they have a fluoroelastomer seal and a polypropylene body for diverting flow in chemical-processing applications. All are full port, so they do not restrict flow.
Valves with a side-port inlet direct flow from the right port to the center or left port. They cannot shut off flow.
Valves with any port inlet can use any port as an inlet or outlet. Turn the handle to direct flow from the inlet port to one outlet port at full capacity, direct flow to both outlet ports simultaneously at reduced capacity, or shut off flow completely.
