Compact Threaded On/Off Valves for Chemicals
For chemical-processing applications in confined areas, these valves have a low-profile handle to fit in tight spots. A rubber seal and a plastic body stand up to aggressive, corrosive solutions.
Polypropylene valves are the most chemical resistant. They handle a wide range of acids, solvents, and other harsh substances.
Full-port valves do not restrict flow. 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.

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.

Easy-to-Install Threaded On/Off Valves for Chemicals
For fast installation and removal from pipelines, these valves have union fittings that disassemble into multiple pieces. All have a plastic body that can stand up to aggressive and corrosive solutions in chemical-processing applications.
Flow-indicating T-handles show the percentage the valve is open.
Standard-port valves slightly restrict flow.

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.

Perform valve maintenance without unthreading pipe connections. These valves have a three-piece bolted body that comes apart for inline access to internal components. The fluoroelastomer seal and glass-filled polypropylene body can withstand aggressive and corrosive solutions for diverting flow between ports in chemical-processing applications. Valves are full port, so they do not restrict flow.
Valves with a center-port inlet direct flow to either side port. They cannot shut off flow.
Valves with a bottom-port inlet direct flow to either side port or shut off flow completely.
T-handles resist accidental movement when snagged or bumped.

On/Off Valve Bodies


Automatically or manually start and stop flow in your line with these valve bodies, which attach to your actuator. They have a full port, so they don’t restrict flow. All meet standard ISO 5211 mounting dimensions. Use valve stem adapters to mount to valve actuators with a larger stem opening.
316 stainless steel valve bodies have excellent corrosion resistance.
Three-piece valve bodies are easy to maintain because you can take them apart without removing them from your line.
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-to-Install Threaded Check Valves for Harsh Chemicals


To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings. The plastic body and fluoroelastomer seal provide excellent chemical resistance. Valves open to allow flow in one direction and close when flow stops or reverses.
Polypropylene valves are more corrosion resistant than PVC or CPVC 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.

Easy-to-Install Plastic Threaded Flow-Adjustment Valves


- Valve Type: Ball
- For Use With: Ammonia, Butane, Citric Acid, Hydrochloric Acid, Methanol, Nitric Acid, Phosphoric Acid, Salt Water, Sodium Hydroxide, Water
- Seal Material: EPDM Rubber
A threaded union on these valves makes them easy to install and remove without disrupting your line. They’re a good choice for lines that require frequent maintenance or cleaning. They thread together or apart with only a turn to the union fitting, unlike other threaded flow-adjustment valves that require repositioning your pipe or valve. The union fitting slides over your pipe, and the threaded fitting sits inside. Ideal for metering, sampling, and other applications, these valves gradually open and close to adjust flow as you turn the handle. A dial displays the percentage you’ve opened them. With a standard port, they’ll slightly restrict flow even when fully open. These valves come with socket-connect fittings for making threaded-to-threaded connections or adapting threaded to socket connections.
