309 Products

On/Off Valves

Threaded On/Off Valves

Use these valves in general purpose applications such as those with water, oil, air, and inert gas.

Fast-Acting Panel-Mount Threaded On/Off Valves

Open and close these valves with the flip of the toggle switch. They’re often used for equipment testing and gas sampling. All have threads and a hex nut below the handle for installation in instrument panels. Use with water, oil, air, and inert gas.

On/Off Valves with Barbed Fittings

Metal provides more durability than plastic. These valves have barbed fittings that grip onto tubing for a secure hold. Use them with water and air.

On/Off Valves with Compression Fittings

For more durability than plastic valves, these are made of metal. A compression sleeve bites into tubing as you tighten the nut, forming a strong seal. Use these valves with water, oil, air, inert gas, and steam.

Plastic On/Off Valves with Push-to-Connect
Fittings for Drinking Water

For a lightweight and economical alternative to metal, these valves are made of plastic. Insert tubing into the fittings—no heat, solder, or flux required. All meet NSF/ANSI 61 for use in drinking water systems.

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.

Compact Threaded On/Off Valves for Fuel

A low-profile handle allows these valves to fit in low-clearance pipelines for diesel fuel, fuel oil, gasoline, and kerosene.

High-Flow Air-Driven On/Off Valves

For use in general purpose applications with water, oil, and inert gas.

Heavy-Use High-Flow Air-Driven On/Off Valves

Limit wear and damage in high-cycling applications—these valves have additional seals that prevent leakage to reduce maintenance time.

Motor-Driven On/Off Valves

For general purpose applications with water, oil, and inert gas.

Precision Flow-Adjustment Valves

Easy-Set Threaded Precision Flow-Adjustment Valves

The color-coded threads and numerical markings on these valves ensure consistent and repeatable settings. One full revolution of the handle reveals a new color to indicate the set point. Use 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.

Threaded Precision Flow-Adjustment Valves

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.

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 Compression Fittings

A compression sleeve bites into tubing as you tighten the nut, forming a strong seal. These valves are for use with air. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves
with 45° Flared Compression Fittings

With 45° flared tube fittings, these valves form a tight seal on metal tubing. Use with air. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Threaded Precision Flow-Adjustment Valves for Fuel

Valves have NPT connections for use with threaded pipe. Turn the handle to adjust the flow of butane, diesel fuel, fuel oil, gasoline, kerosene, natural gas, and propane in small increments.

Precision Flow-Adjustment Valves
with Barbed Fittings for Fuel

Add fine flow control to tubing lines for oil, butane, diesel fuel, fuel oil, gasoline, kerosene, natural gas, and propane. These valves have a barbed fitting that grips onto tubing, providing a secure hold. Turn the handle to adjust flow in small increments.

Check Valves

Threaded Check Valves

For use with threaded pipe, these valves are available with NPT, NPTF, BSPP, BSPT, and UNI/UNF (JIC) connections.

Check Valves with Push-to-Connect
Fittings for Harsh Chemicals

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

Pipe, Tubing, Hose, and Fittings

Compact Quick-Disconnect Hose Couplings for Air

A slim body allows these couplings to fit into tight spaces. Compatible with Compact-shape plugs and sockets.

High-Pressure Thread-Lock Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Use these couplings at pressures up to 10,000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

Natural and LP Gas Hose Fittings

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket that connect and disconnect quickly.

Brass Push-to-Connect Tube Fittings for Air

Made of brass, these fittings have good corrosion resistance.

Universal-Thread Push-to-Connect
Tube Fittings for Air and Water

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

Hydraulic Valves

Flow-Adjustment Inline Hydraulic Valves

Adjust the flow rate as needed.

Precision Flow-Adjustment Inline Hydraulic Valves

A tapered needle gives you more precise control than standard flow-adjustment inline hydraulic valves.

Adjustable Flow-Regulating Inline Hydraulic Valves

Set your flow rate and then adjust it as necessary; these valves maintain flow rate despite pressure changes in the system.

Flow-Regulating Inline Hydraulic Valves

Maintain a fixed flow rate even if pressure changes in the system.

Backflow-Prevention Inline Hydraulic Valves

Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.

NFPA Valve-Mounting Blocks

NFPA valve-mounting blocks have standardized valve mounting patterns to keep hydraulic lines compact and organized.

Hydraulic Jacks

Flow-Adjustment Manifolds for Hydraulic Jacks

Connect up to four rams and a gauge to a pump. Ram connections have flow-adjustment valves to adjust ram speed, or shut it off to temporarily hold a load.

Compact Manifolds for Hydraulic Jacks

Connect up to five rams to a single pump.

Flow-Adjustment Valves for Hydraulic Jacks

Control the flow of oil to adjust ram speed, or shut it off to temporarily hold a load.
