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.

High-Pressure Threaded Precision
Flow-Adjustment Valves for Steam

To withstand a maximum steam pressure of at least 4,800 psi @ 355° F in applications such as petroleum refineries, these valves are machined from a single piece of metal for seamless construction. 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 Steam

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. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Create one action with these valves, such as extending a cylinder.

Multiple-Position Single-Action
Air Directional Control Valves

Control six different outputs from a single source of airflow. These valves have one inlet port and six outlet ports. Push in and rotate the dial to move between outlet ports and send airflow to a different output.

Remote-Location Two-Hand
Single-Action Air Directional
Control Valves

The push buttons that operate these valves are separate from the logic unit, allowing you to position them away from machinery. Since both hands are required to simultaneously press the buttons, they protect workers from accidental machinery start-up. They create one action, such as extending a cylinder.

Key-Operated Single-Action
Air Directional Control Valves

Because they require a key to operate, you can limit who is able to adjust these valves. They create one action, such as extending a cylinder.

Two-Speed Two-Action Air
Directional Control Valves
with Exhausting Shut-Off

In the off position, these valves exhaust all air pressure, allowing the equipment to return to the neutral position. 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. Also known as 4-way and 5/3 exhaust center valves.

Two-Speed Two-Action Air

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 4-way and 5/2 valves.

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

Because they require a key to operate, you can limit who is able to adjust these valves. 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. Also known as 4-way and 5/2 valves.

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

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

Single-Action Mechanically Operated
Air Directional Control Valves

A simple automation solution that requires no programming, these valves are activated when an object, such as a box rolling on a conveyor, pushes the actuator. They create one action, such as extending a cylinder. Also known as 3-way and 3/2 valves.
