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.

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.

Flanged Air-Driven On/Off Valves for Chemicals
- Valve Type: Ball
- For Use With: Water, Oil, Air, Natural Gas, Propane, Butane, Acetone, Argon, Carbon Dioxide, Deionized Water, Diesel Fuel, Ethanol, Ethylene Glycol, Fuel Oil, Gasoline, Helium, Kerosene, Methanol, Methyl Ethyl Ketone, Mineral Spirits, Neon, Nitric Acid, Nitrogen, Oxygen, Salt Water, Soap Solutions, Steam, Xenon, Citric Acid, Krypton
- Ball Material: 316 Stainless Steel
- Seal Material : PTFE Plastic
- Seat Material: PTFE Plastic
- Actuator Housing Material: Aluminum
- Specifications Met: ASME B16.34
A 316 stainless steel body and a PTFE seal stand up to aggressive and corrosive solutions in chemical-processing applications. Their ball-valve design allows these valves to handle at least three times the flow of standard flanged valves. For faster actuation than motor-driven valves, they operate on compressed air. 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 automatically start and stop flow and don't require a minimum pressure drop between the inlet and outlet for operation.
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. 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 fail in place; upon the loss of power, the valve will remain in its current position. 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.
