Two-way valve, fluid control part terminology, is a control valve with two lines. However, the valve with two lines is not necessarily a two-way valve, the basic characteristics of two-way valve is: two-way on-off! When the two lines can only achieve one direction of conduction, known as the one-way valve. VVF45 flange two-way valve two-way valve is divided into two types of normally open and normally closed: 1. Normally open two-way valve normally open the valve, equivalent to a pipeline, to achieve unimpeded conduction fluid, but when changing the valve state , It will shut down, cut off the fluid conduction. 2. Normally closed two-way valve usually valve is closed, able to cut off the fluid conduction, when changing the valve state, to achieve fluid flow. Control Category: 1. Manual two-way valve, the valve operation requires manual manual operation, lower cost, mostly used in daily life, can also be used in infrequently switch the occasion. 2. Two-way solenoid valve, this valve is equivalent to the solenoid to replace the human valve to achieve continuity, suitable for use in automated production, the relative increase in costs. 3. Pneumatic, hydraulic two-way valve, the valve and solenoid valves are high level of automation of the valve, which has the advantage of being able to achieve greater pressure fluid control, more adequate force, but the cost is higher than the solenoid valve .
