Pneumatic double three-way ball valve
Product Overview
Pneumatic double three-way ball valveDouble pneumatic three-way ball valve, double pneumatic three-way threaded ball valve, pneumatic double three-way threaded ball valve, pneumatic double three-way L-shaped ball valve, pneumatic double threaded three-way ball valve, one control two pneumatic three-way threaded ball valve, pneumatic double three-way T-shaped ball valve, one drag two pneumatic three-way ball valve, pneumatic stainless steel double three-way ball valve. The pneumatic double threaded T-shaped three-way ball valve is composed of a pneumatic piston type double acting or single acting actuator and two three-way L-shaped or T-shaped stainless steel ball valves. The double three-way ball valve is divided into L-shaped and T-shaped, and the medium flow direction is shown in the following figure. The L-shaped pneumatic three-way ball valve is suitable for switching the flow direction of the medium and can connect two perpendicular channels; The T-shaped pneumatic three-way ball valve is suitable for medium diversion, merging, or flow direction switching. The T-shaped hole can connect three channels to each other or two of them. Pneumatic three-way ball valves generally adopt a two seat structure, but can also adopt a four seat structure according to user requirements. The standard core has an L-shaped three-way dual channel design. By changing the relative angle between the core and the pipeline, different combinations of fluid control can be achieved for the three pipelines; The T-shaped pneumatic three-way internal thread ball valve can play a proportioning role and is suitable for adjusting and controlling the proportioning of liquid, gas, steam and other media. There is a proportional adjustment type (using an electric pneumatic valve positioner, powered by electrical signals and compressed air, receiving 0-10mA DC or 4-20mA DC current signals from the control system input, changing the rotation angle of the ball core to achieve proportional adjustment action). Two position switching type (using electromagnetic directional valve and valve position feedback device, powered by AC220V or DC24V power supply voltage and compressed air, to achieve rapid switching control of fluid medium).
