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, Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen, Methanol, Neon, Xenon, Xylene
- Ball Material: 316 Stainless Steel

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 PEEK 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.

On/Off Valves with Yor-Lok Fittings 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, Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen, Methanol, Neon, Xenon
- Ball Material: 316 Stainless Steel
- Seal Material: PTFE Plastic
- Seat Material: PTFE Plastic
- Specifications Met: ANSI/ASME B16.34
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 316 stainless steel body that can stand up to aggressive and corrosive solutions in chemical-processing applications. All are standard port, so they slightly restrict flow.
High-Flow Flanged Air-Driven On/Off Valves
- Valve Type: Ball
- For Use With: Oil, Air, Natural Gas, Propane, Butane, Argon, Diesel Fuel, Ethylene Glycol, Fuel Oil, Gasoline, Helium, Kerosene, Liquid Argon, Liquid Nitrogen, Neon, Steam, Xenon, Krypton
- Seal Material : PTFE Plastic
- Specifications Met: ANSI B16.34
Their ball-valve design allows these valves to handle three times the flow of other flanged valves. They operate on compressed air to automatically start and stop flow faster actuation than motor-driven valves. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation. All are full port, so they do not restrict flow.
The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied to close them, so they do not have a valve starting position.
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.

For high-flow chemical-processing applications, these valves have a ball-valve design that provides at least three times the flow of standard flanged valves. They have a 316 stainless steel body and a PTFE seal that can stand up to aggressive and corrosive solutions. Valves operate on electricity to automatically start and stop flow. They don’t require a minimum pressure drop between the inlet and outlet for operation. All are normally open unless actuated. Valves are full port, so they do not restrict flow.
The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. Two single pole, double throw (SPDT) auxiliary switches allow you to connect these valves to temperature-monitoring equipment, programmable logic controllers, or conveyor sirens. The internal heater automatically turns on when the valve is actuated to prevent motor damage caused by condensation buildup. The manual override allows you to operate the valve during power outages.
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.
