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.

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.

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.

Flow-Adjustment Valve Bodies
Attach these valve bodies to your actuator to automatically or manually control flow in your line. Also known as V-ball valve bodies, they have a V-cut opening that gradually increases flow as you open the valve. They don’t restrict flow because they have a full port. Made from 316 stainless steel, they have excellent corrosion resistance. All meet standard ISO 5211 mounting dimensions. Use valve stem adapters to mount to valve actuators with a larger stem opening.
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 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.
