About On/Off Valves

Easy-Set Threaded Plastic Precision
Threaded Flow-Adjustment Valves

To ensure consistent and repeatable settings, these valves have color-coded handle threads and numerical markings. One full revolution of the handle reveals a new color to indicate the set point. Use these valves with water, oil, air, and inert gas. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves with
Push-to-Connect Fittings for Chemicals

Insert tubing into the fittings on these valves—no heat, solder, or flux required. With a fluoroelastomer seal and a PVDF body, they can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves
with Barbed Fittings for Chemicals

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a PTFE seal and a PVDF body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves
with Yor-Lok Fittings for Chemicals

For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. The 316 stainless steel body and seal, the PTFE seat and packing, and the Monel needle can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Flanged Flow-Adjustment Valves for Chemicals

Metal provides more durability than plastic. With seats that can stand up to aggressive and corrosive solutions, these valves are often used in chemical-processing applications. They bolt to flanges to adjust and regulate flow in flanged pipelines.

Miniature Threaded On/Off Valves for Chemicals

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.

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 fluoroelastomer seal and a plastic body that can stand up to aggressive and corrosive solutions in chemical-processing applications.

Easy-Clean Threaded On/Off Valves for Chemicals

There’s no need to unbolt these valves for cleaning—remove the valve 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 to withstand aggressive and corrosive solutions in chemical-processing applications.

On/Off Valves with Push-to-Connect
Fittings for Chemicals

Insert tubing into the fittings on these valves—no heat, solder, or flux required. To withstand aggressive and corrosive solutions, they have a chemical-resistant fluoroelastomer seal and a plastic body.

On/Off Valves with Barbed Fittings for Chemicals

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.

Compact Versa-Mount Air-Driven On/Off Valves

About half the height of our other versa-mount valves, these fit in tight spots.

Versa-Mount Air-Driven On/Off Valves

A compact, lightweight actuator and an angular body allow you to install these valves in any mounting orientation.

Flanged Air-Driven On/Off Valves for Chemicals

With a ball-valve design, these valves can handle three times the flow of butterfly valves.

Sanitary Air-Driven On/Off Valves

Use air pressure to automatically control the flow of liquids in sanitary environments, such as food and beverage processing plants.

Flanged Motor-Driven On/Off Valves for Chemicals

For three times the flow of butterfly valves, these have a ball valve design.

Diverting Valves with Barbed Fittings for Chemicals

Barbed fittings on these valves grip onto tubing, providing a secure hold. To divert flow between ports in chemical-processing applications, they have a chemical-resistant seal and a PVDF body to withstand aggressive and corrosive solutions.

Easy-Clean Threaded Diverting Valves for Chemicals

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.

Solenoid Diverting Valves for Chemicals

Often used for chemical analysis and other laboratory testing, these valves have a PTFE seal and body to withstand aggressive and corrosive solutions. They operate on electricity to automatically divert flow between ports.

Vacuum-Breaking Valves for Chemicals

A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals.

Flow-Control Orifices

Barbed Flow-Control Orifices

Insert the barbed ends of these orifices into rubber and soft plastic tubing, and secure them with a clamp.

Flow-Control Orifices for Chemicals

Made of PVC, these orifices have excellent resistance to a wide range of corrosive chemicals.

Flowmeters for Oxygen

Calibrated, cleaned, and bagged for oxygen service, these flowmeters are commonly used for welding.

Quick-Disconnect Hose Couplings for Compressed Gas

These couplings consist of a plug and socket that connect and disconnect quickly. Use them if you need to frequently link and unlink welding hoses, torches, and regulators. They are also known as CGA couplings.
