Panel-Mount Precision Compressed Air Regulators

Centralize control for your air regulators—these regulators mount into a panel, cabinet, or control box. The inlet and outlet are on the bottom, so you can route air lines in tight quarters behind the panel. Use them where you need consistent air pressure to generate precise force and movement. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after your filters.

Miniature Panel-Mount Pressure-Regulating Valves for Water, Air, and Inert Gas

Our smallest pressure-regulating valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure in tight spaces where other valves can't fit. Adjust the outlet pressure within the range. Valves have threads below the adjustment screw and comes with a panel-mount nut. Body is nickel-plated brass for good corrosion resistance.

Inline Air Flow Control Valves

Designed to be mounted inline, these valves can be installed in an easy-to-reach location along your line. Flow control valves control the speed of air-powered equipment by adjusting the volume of airflow. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. Typically, valves are installed to control flow as it exits the cylinder (meter out), but they may also be installed to control flow as it enters the cylinder (meter in). For the best control, mount them as close to the cylinder as possible to minimize the length of tubing or piping between the cylinder and the valve.

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.

Elbow Air Flow Control Valves with Flow Indicator

A flow indicator on these valves provides a relative measure of the air flowing through the valve, from off to full volume, similar to the volume dial on a speaker. The indicator’s numeric increments make it easy to set the valve to the same flow rate with each use. These valves adjust the volume of air exiting an air cylinder (meter out) to control the speed of air-powered equipment. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional tubing between the cylinder and valve for better control and consistency than inline valves. Insert plastic or soft metal tubing into the push-to-connect outlet ports.

Panel-Mount Back-Pressure-Regulating Valves for Air and Inert Gas

Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel. Often used in systems running on air compressors, they're installed after pressure-sensitive equipment to obstruct flow and maintain a consistent operating pressure. If the system pressure exceeds the set pressure, they exhaust through the outlet. Adjust the set pressure within the range.

Corrosion-Resistant Single-Control Two-Direction Air Flow Control Valves

Made of polybutylene, these plastic valves are more corrosion resistant than valves made of aluminum or nylon. A single dial regulates the speed of airflow in two directions as it enters (meter in) and exits (meter out) equipment, and are often used to control the extension and retraction speed of an air cylinder at the same time. Insert plastic or soft metal tubing into the push-to-connect outlet ports; the outlet ports swivel 360° so you can make a connection from any direction. The elbow shape allows you to mount these valves directly to cylinder ports, eliminating additional tubing between the cylinder and valve for better control and consistency than inline valves.

Elbow Corrosion-Resistant Air Flow Control Valves

Mount these valves directly to cylinder ports, eliminating additional tubing or piping between the cylinder and valve for better control than inline valves. Made of stainless steel and plastic parts, they’re more corrosion resistant than valves made of brass, aluminum, or zinc alloy. Use them to control the speed of air-powered equipment by adjusting the volume of airflow. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction.

Precision-Adjust Air Flow Control Valves

A fine-adjustment dial allows tighter control of airflow and cylinder speed than with other flow control valves. These valves control the speed of air-powered equipment by adjusting the volume of airflow. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction.

Plastic Panel-Mount Pressure-Regulating Valves for Air

Regulate pressure in air systems from your instrument panel—these valves have threads below the adjustment knob and come with a panel-mount nut. All automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Body is polysulfone, which is lightweight and corrosion resistant.
