Flow-Control Orifices for Chemicals
- For Use With: Air, Ammonia, Sodium Hydroxide, Beverage, Carbon Dioxide, Diesel Fuel, Water, Oil, Ethylene Glycol, Food, Hydrochloric Acid, Kerosene, Liquid Carbon Dioxide, Methanol, Soap Solutions, Methyl Ethyl Ketone, Mineral Spirits, Natural Gas, Oxygen, Nitric Acid
- Max. Pressure: 120 psi @ 75° F
- Temperature Range: 40° to 140° F
Made of PVC, these orifices have excellent resistance to a wide range of corrosive chemicals. Also known as flow restrictors and precision orifice valves, they are used to throttle, vent, bleed, or regulate the flow of liquids and gases. They automatically adjust to changing inlet pressure to maintain consistent outlet flow.

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.

No need to remove these valves from your line to access their internal components—the three-piece bolted body comes apart. Ideal in chemical-processing applications, the seal and polypropylene body stand up to aggressive and corrosive solutions.
Valves with a lever handle give you more leverage than valves with T-handles, so you can quickly open and close them with ease. To limit access to your line, replace the handle with a locking handle (sold separately). Fix the handle in place using a padlock (not included) with a shackle diameter up to 19/64". Valves with a T-handle are more compact than valves with a lever handle, so they fit in tighter spots. They also resist accidental movement when snagged or bumped.
Valves with a cam-and-groove male plug quickly connect and disconnect medium- to large-diameter hose lines. Insert the plug end into a cam-and-groove female socket.
Valves with a fluoroelastomer seal fit snug even when surfaces are irregular, misaligned, or dirty. The seal compresses and conforms to create a tight, leakproof connection. Pick valves with a PTFE seal if you frequently need to open and close valves. The seal is slippery to reduce friction and prevent wear.
Full-port valves do not restrict flow. Standard-port valves slightly restrict flow.

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.

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.

Also known as diaphragm valves, these have a PTFE body and seals that stand up to harsh acidic solutions. The diaphragm can handle dirty liquid, slurries, and abrasive media without damage. All valves operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) 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 have a single-acting actuator that only requires air pressure to open the valve; they automatically spring closed when the air turns off. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Valves are normally closed unless actuated.
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.
