The control valve handbook has been a primary reference since its first printing in 1965. The basics of pneumatic control valves machine design. Flow control valves are designed to provide an adjustable restriction for varying or metering fluid flow in one direction through the valve and full flow in the opposite direction through the same valve. Pneumatic cylinders pneumatic valves and nfpa square. Pneumatic valves and motion control 2, 3, and 4way valves, available with electric, manual. Control valves may be broadly classified by their function as onoff type or flow regulating type. With the piston at the bottom of its stroke, inlet.
Properly selected and maintained control valves increase efficiency, safety, profitability, and ecology. Flow control valves key features function flow control or oneway flow control valves regulate the piston speed of pneumatic drives during advance and return strokes. Introduction to pneumatics and pneumatic circuit problems. This is done through suitable restriction of the flow rate of compressed air in exhaust air or supply air direction. Emerson is where technology and engineering come together to create solutions for the benefit of our customers, driven without compromise for a world in action. The 3250 series flow control valves are also suitable for low pressure hydraulic service. Control valves are an increasingly vital component of modern manufacturing around the world. Oneway flow control valves key features function flow control or oneway flow control valves regulate the piston speed of pneumatic drives during advance and return strokes. For most double acting cylinder applications, two flow control valves should be used. Alpha series high flow, 2and3position, 4way valves that are compact in.
