The most common directional control valve is a 4/3-way valve, which means the valve has four working ports and three spool positions. The 2-way directional control valve is the simplest directional control valve that has two ports called inlet and outlet. A 3-way directional control valve has 3 working ports called inlet, outlet and exhaust.

Control Valve Products · Provide constant pressure regardless of process variables such as flow or upstream variation · Help system operate more economically by 

typically reduces the pressure to 18 to 22 psi. For two-pressure (day/night) systems and for systems designed to change from direct to reverse acting (heating/cooling), the PRV switches between two pressures, such as 13 and 18 psi. The maximum safe air pressure for most pneumatic controls is 25 psi. C2353 COMPRESSED AIR SUPPLY SYSTEM MAIN

Choose from our selection of pneumatic control valves, including over 1,600 products in a wide range of styles and sizes. In stock and ready to ship. BROWSE CATALOG. Protect air-powered equipment in emergency shut-off situations— when system pressure drops, these valves automatically close to stop cylinder motion, even at mid-stroke.

02/09/  · For example, a five-port three-position valve has port 1 as its pressure inlet, ports 3 and 5 as work ports, and ports 2 and 4 as exhaust ports. Arrangements for pneumatic valves that are regularly used are 5/3, 5/2, 4/2, 3/2, and 2/2. They control airflow in a pneumatic system and liquid in a hydraulic one. You can get either a valve with

Air-piloted valves rely on air pressure from a pneumatic system, rather than electrical current or manual intervention, to control compressed air, liquids or gas in industrial automation or industrial process applications. While air-piloted valves are often specified where an air pressure-based operating system already exists, the absence of electrical current and manual involvement also make

The basics of pneumatic control valves. Aug. 8, 2002. Directional valves such as Parker Hannifin's B3G-Series threeway (left) and four-way valves are often used to control pneumatic operations

Proportional valves come with a wide variety of actuation methods, for example, a voltage, current, step-input or digital input. They can be designed into a control system that is closed-loop, with feedback from an electronic flow meter, or open-loop. These valves are ideal for applications where the flow requirement is continually changing.
