About On/Off Valves

Easy-to-Install Plastic Threaded On/Off Valves

These valves have union fittings that disassemble for fast installation and removal from pipelines. Use with water, air, and inert gas.

Socket-Connect On/Off Valves for Drinking Water

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves meet NSF/ANSI 61, which means they’re safe to use with drinking water systems.

Easy-to-Install Socket-Connect
On/Off Valves for Drinking Water

For fast installation and removal from pipelines, these valves have union fittings that disassemble into multiple pieces. Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves meet NSF/ANSI 61 for use in drinking water lines.

Plastic Threaded On/Off Valves for Drinking Water

These valves meet NSF/ANSI 61 for use in drinking water lines.

Easy-to-Install Plastic Threaded
On/Off Valves for Drinking Water

Disassemble the union fittings on these valves for fast installation and removal from your pipeline. All meet NSF/ANSI 61 for use with drinking water.

Threaded On/Off Valves for Chemicals

With a fluoroelastomer seal and a CPVC body, these valves can withstand aggressive and corrosive solutions in chemical-processing applications.

Compact Threaded On/Off Valves for Chemicals

For chemical-processing applications in confined areas, these valves have an EPDM seal and a PVC or CPVC body to withstand aggressive and corrosive solutions and a low-profile handle to fit in tight spots.

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-to-Install Socket-Connect
On/Off Valves for Chemicals

Union fittings on both ends of these valves disassemble for fast installation and removal from your pipeline. Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves have a fluoroelastomer seal and a plastic body that can withstand aggressive and corrosive solutions in chemical-processing applications.

Socket-Connect On/Off Valves for Chemicals

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves have a fluoroelastomer seal and a plastic body that can withstand aggressive and corrosive solutions in chemical-processing applications.

Threaded Gradual On/Off Valves for Chemicals

For use with threaded pipe, these valves have NPT connections.

Socket-Connect Gradual
On/Off Valves for Chemicals

These valves have socket-weld connections for bonding to unthreaded male plastic pipe.

Solenoid On/Off Valves for Chemicals

With a plastic body and a fluoroelastomer seal, these valves can stand up to aggressive and corrosive solutions in chemical-processing applications.

Easy-to-Install Plastic Motor-Driven On/Off Valves

Separate the union fittings on each end of these valves for fast installation and removal from pipelines.

Motor-Driven On/Off Valves for Chemicals

All valves have threaded NPT connections.

Plastic Flanged Flow-Adjustment
Valves for Chemicals

In addition to fluoroelastomer seats that resist a wide range of chemicals, these valves have no metal parts to corrode, so they’re often used for chemical-processing applications in corrosive conditions. All bolt to flanges to adjust and regulate flow in flanged pipelines.

Flanged Flow-Adjustment Valves for Drinking Water

These valves meet NSF/ANSI 61 for use with drinking water. They bolt to flanges to adjust and regulate flow in flanged pipelines.

Easy-to-Install Threaded Diverting Valves

For easy installation and removal from pipelines, all ends on these valves have union fittings that disassemble into multiple pieces. Use with water. Valves divert flow between ports.

Easy-to-Install Threaded
Diverting Valves for Chemicals

For easy installation and removal from pipelines, all ends on these valves have union fittings that disassemble into multiple pieces. Their fluoroelastomer seal and plastic body can withstand aggressive and corrosive solutions for diverting flow between ports in chemical-processing applications.

Union Fittings for Flow-Control Valves

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.

Threaded Check Valves for Harsh Chemicals

These valves open to allow flow in one direction and close when flow stops or reverses.

Socket-Connect Check Valves for Harsh Chemicals

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.
