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.

Threaded Isolation On/Off Valves for Chemicals

- Valve Type: Ball
- For Use With: Acetone, Air, Ammonia, Argon, Carbon Dioxide, Deionized Water, Diesel Fuel, Ethanol, Fuel Oil, Gasoline, Helium, Isopropyl Alcohol, Kerosene, Krypton, Methanol, Neon, Xenon, Xylene
- Ball Material: 316 Stainless Steel
- Seal Material: PTFE Plastic
- Seat Material: PEEK Plastic
- Specifications Met: ASME B16.34
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.

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.

On/Off Valves with Barbed Fittings for Chemicals
Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.
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: Air, Argon, Butane, Carbon Dioxide, Citric Acid, Deionized Water, Diesel Fuel, Ethylene Glycol, Gasoline, Helium, Hydrochloric Acid, Isopropyl Alcohol, Krypton, Mineral Spirits, Natural Gas, Neon, Nitric Acid, Nitrogen, Oil, Oxygen, Phosphoric Acid, Propane, Salt Water, Soap Solutions, Sodium Hypochlorite, Sulfuric Acid, Water, Xenon, Xylene
- Ball Material: PVDF Plastic
- Seal Material: Fluoroelastomer Rubber
- Seat Material: Fluoroelastomer Rubber

Flanged On/Off Valves for Chemicals
Bolt these valves to ANSI flanges—they meet ASME dimensional standards. They have a plastic body and a seal that withstand aggressive and corrosive solutions in chemical-processing applications.
Glass-filled vinyl ester valves stand up to a wide variety of harsh acids and solvents. You can rely on them for repeated use, changes in pressure and flow rate, and hot and cold conditions.
Valves with a lockable lever handle can be fixed in place with a padlock (not included). They give you more leverage than short lever handles, so you can quickly open and close the valve with minimal effort.
Standard-port valves 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.
