气动三通调节阀 特点 Features of ZXQ pneumatic three-way control valve

1. The flow direction of the valve core is in the flow open state, so the valve can work stably.
2. In addition to the bushing guidance at the upper bonnet, the side of the valve core and the inner surface of the valve seat also have a guiding effect, a large guiding area and reliable work.
3. The actuator adopts a multi-spring structure, which reduces the height by 30%. 30% lighter.
