On/Off Valves with Compression Fittings
Made of metal, these valves are more durable than plastic valves and withstand higher temperatures. A compression sleeve bites into tubing as you tighten the nut, forming a strong seal.
Lever handles give you the most leverage for quickly opening and closing valves with minimal effort.Full-port valves do not restrict flow.Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
- Valve Type: Ball
- For Use With: Drinking Water, Oil, Steam, Water
- Seal Material: Buna-N Rubber
- Specifications Met: NSF/ANSI 61

Fast-Switching Two-Speed Two-Action Electrically
Operated Air Directional Control Valves
Run through equipment cycles up to 30% faster than with standard valves. These valves shift between flow positions in 1.7 ms. 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. Also known as 4-way and 5/2 valves, they actuate when voltage is applied to the electrical connection. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they go back to their starting position as soon as voltage is removed.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Electrically Operated Air Directional Control Valves with Flow Control
Create motion and control the speed of that motion with a single valve. Also known as 4-way valves, these valves create two actions, such as extending and retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion, and adjust the volume of air exiting an air cylinder (meter out) to control speed. Apply voltage to the electrical connection to actuate.
5/3 (closed center valves) close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. 5/3 (pressure center) valves create two actions at the same time, such as extending two single-acting cylinders at once.
Valves with spring return actuation go back to their original position when voltage is removed. Valves with electric (solenoid) return actuation go back to their original position when voltage moves from the first solenoid to the second solenoid.

Air-Operated Air On/Off Valves
Also known as blocking valves, these valves are activated by an air signal to turn equipment on and off. They allow airflow when an air signal is applied to the air pilot. When the air supply is removed, the valve closes, trapping air in the system.
Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Hydraulic Fluid
Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close against each other, reducing fluid loss when connecting and disconnecting the line. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them when you need frequent access to a line. All of the International Standard ISO Minimal-Spill quick-disconnect plugs are compatible with any of the International Standard ISO Minimal-Spill quick-disconnect sockets of the same coupling size, regardless of the pipe size. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated. They are zinc-plated steel, which has excellent strength and durability and fair corrosion resistance.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.
