Directional valve, what is the direction valve The directional valve is a valve that uses the difference in the relative position between the valve core and the valve body to change the on-off relationship between different pipelines to achieve connection, cut-off, or change the direction of the liquid flow. It has a wide range of uses and many types. The main requirements for the performance of the reversing valve are: 1) The pressure loss of the oil flowing through the reversing valve is...
Manually-actuated valve There are two types of manual directional valves: Spring Reset and Steel Ball OrientaTIon. Figure 5.17 (a) shows a steel ball positioning type three-position four-way manual directional valve. After the handle is pushed by hand to move the valve core relative to the valve body, the valve core can be stabilized in three different working positions by the steel ball . Figure 5.17 (b) is a spring-returning three-position four-way manual directional valve. After pushing the...
In practical applications, the directional control valves can be divided into several categories according to different needs: (1) According to the flow direction of gas in the pipeline, if only gas is allowed to flow in one direction, such a valve is called a unidirectional control valve, Valve, shuttle valve, etc .; can change the gas flow control valve called the valve, such as the commonly used 2way2port, 2way3port, 2way5port, 3way5port and so on.
