505 Products

Control of Liquids, Gases, and Solids

On/Off Valves with Push-to-Connect
Fittings for Food and Beverage

Insert tubing into the push-to-connect fittings on these valves—no heat, solder, or flux required. They meet NSF/ANSI 51 for safe use with food.

High-Pressure Compact Solenoid On/Off Valves

Control flow in high-pressure lines in tight spots—these valves have the highest pressure ratings of our compact valves.

Compact Solenoid On/Off Valves for Coolant

Reduce your pipeline footprint with these low-profile valves that are about half the size of standard valves for coolant.

Plastic Threaded Flow-Adjustment
Valves with Garden Hose Outlet

For lightweight and corrosion-resistant alternative to metal, these valves are plastic. Attach garden hose to the valve outlet. Use with water. These valves gradually open and close to adjust and regulate flow.

Plastic Noncontact Flow-Adjustment Valves

With no metal parts, these valves are often used for noncontact flow adjustment in wet conditions and harsh environments. All press down on the outside of tubing to adjust flow without contacting the process media.

Check Valves with Push-to-Connect Fittings

Insert tubing into the fitting—no heat, solder, or flux required.

Check Valves with Push-to-Connect
Fittings for Drinking Water

Valves have a plastic body.

Heavy Duty Check Valves with
Push-to-Connect Fittings for Drinking Water

The metal body is more durable than plastic.

Threaded Check Valves for Vacuum

Valves have NPT connections for use with threaded pipe.

Push-to-Connect Flow-Control Orifices

Push tubing into these orifices, and an internal ring holds them in place. They're for use with plastic and soft metal tubing.

Compact Float Valves with Plastic
Reservoir for Food and Beverage

Commonly used in ice-making machines, these valves have floats that rest inside a clear plastic reservoir.

Plastic Quick-Disconnect Hose
Couplings for Air and Water

Made of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. Compatible with Plastic-shape plugs and sockets.

Diverting Valves with Fire-Fighting Hose Fittings

Control the flow of water in two directions from a single source—these diverting valves have two balls and handles for independent operation of each outlet. Use with fire-fighting hose.

Right-Angle Flow Rectangular Manifolds

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Tamper-Resistant Compact Pressure-Regulating
Valves for Air and Inert Gas

Prevent changes to your pressure setting—these valves come set at a nonadjustable outlet pressure.

Pressure-Regulating Valves with
Compression Fittings for Food and Beverage

Compression fittings bite down on hard metal and plastic tubing for a tighter seal than push-to-connect fittings.

Threaded Pressure-Regulating
Valves for Food and Beverage

Valves have NPT connections.

Single-Inlet Sink Faucets

Electric-, Air-, and Hydraulic-Powered Motion Control

Two-Speed Two-Action Electrically
Operated Air Directional Control Valves

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Also known as 5/2 valves, they actuate when voltage is applied to the electrical connection.

Two-Speed Two-Action Electrically Operated
Air Directional Control Valves with Full Shut-Off

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Apply voltage to the electrical connection to actuate.

Electrically Operated Air Directional
Control Valves with Flow Control

Use a single valve to create motion and control the speed of that motion.

NPT-to-BSPP Adapting Compressed Air
Filter/Regulators for Particle Removal

No need for thread adapters—these filter/regulators have an NPT inlet and a BSPP outlet.

DIN-Mount Compressed Air
Filter/Regulators for Particle Removal

Mount these filter/regulators to a 35 mm DIN rail with the included brackets.

Compressed Air Filter/Regulator Manifolds

Use a single air supply to distribute air to up to four locations. In addition to the outlet for inline connection, these manifolds have three 1/4 NPT female outlets for connection to air-powered tools and equipment.
