Product Description
Directional control valves are control elements used to change the direction of gas flow in pipelines. These valves are widely used in various pipeline constructions, such as natural gas regional transportation, heating transportation, and gas laboratory research applications, etc. In practical applications, directional control valves can be classified into several categories according to different needs. In practical applications, directional control valves can be classified into several categories according to different needs: According to the flow direction of the gas in the pipeline, if the gas is only allowed to flow in one direction, such a valve is called a one-way control valve, such as a one-way valve, shuttle valve, etc.; the control valve that can change the gas flow direction is called a reversing valve, such as the commonly used 2way2port, 2way3port, 2way5port, 3way5port, etc.
According to the control method, they can be classified as electromagnetic valves, mechanical valves, pneumatic valves, and manual valves. Among them, the electromagnetic valves can be further divided into single and double electric control valves; mechanical valves can be divided into ball valves, roller valves, and other types; pneumatic valves can also be divided into single pneumatic and double pneumatic valves; manual valves can be divided into manual valves and foot-operated valves. According to the working principle, they can be classified as direct-acting valves and pilot-operated valves. The direct-acting valve is a valve that directly achieves the direction-changing requirement by human power or electromagnetic force, pneumatic force; the pilot-operated valve is composed of a pilot head and the valve body, and the pilot head piston drives the valve stem inside the valve body to achieve direction-changing.Based on the position of the valve spool, valves can be classified into 2-way and 3-way valves.
According to the number of gas holes on the valve, they can be classified as 2-port, 3-port and 5-port valves.
