Modular Air Directional Control Valves with Air Manifolds
Mount valves to a single-station base or to a manifold, which allows a single pressure source for multiple valves, then add or remove valves as your needs change. Valves with the same style can be used on the same manifold. For example, you can put a Style B, 2-position, spring-return valve and a Style B, 3-position, solenoid-return valve on the same manifold.
3-way valves create one action, such as extending a cylinder. 4-way valves create two actions, such as extending and retracting a double-acting cylinder.
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 (exhaust center) valves exhaust all air pressure in the off position, allowing equipment to return to the neutral position. 5/3 (pressure center) valves create two actions at the same time, such as extending two single-acting cylinders at once.
Normally closed valves block airflow until actuated.
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.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Modular Air Directional Control Valves with Air and Electrical Manifolds
Mix and match valve styles on one manifold to meet your control needs. Mount multiple valves to a manifold to reduce piping requirements and create multiple actions from a single pressure input. Add or remove valves as your needs change.
3-way valves create one action, such as extending a cylinder. They have four flow positions, which allows the valve to operate as two independent valves from a single station on the manifold. 4-way valves create two actions, such as extending and retracting a double-acting cylinder.
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 (exhaust center) valves exhaust all air pressure in the off position, allowing equipment to return to the neutral position. 5/3 (pressure center) valves create two actions at the same time, such as extending two single-acting cylinders at once.
Normally closed valves block airflow until actuated.
Valves with air pilot return actuation go back to their starting position when the air supply is moved from the first air pilot to the second air pilot. Valves with electric (solenoid) return actuation go back to their original position when voltage moves from the first solenoid to the second solenoid.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Air-Pulse Flow Control Valves for Filter Cleaning
Designed for use in dust-collection systems, these normally closed diaphragm valves periodically burst air to knock debris from filters. Connect the valve’s inlet port to your air supply, and connect the outlet port to the blow tube in your system.
A solenoid is required to actuate the valve.
Flow coefficient (Cv) is a measurement that indicates how much airflow a control valve can provide to your cylinder.
