Pneumatic T-connected Angle Valve

The valve body adopts the T-way combination,and the link between the valve body adopts two symmetrical bolts gland type structure,which can  realize the neat array way to quickly combine,minimize the structure to save space,and the performance is reliable and stable.

Working principle

Pneumatic T-connected angle valve working principle:

In non-working state,due to the action of the spring,the valve body under the seat seal port is normally  open or normally closed,and the left and right channels are connected through.

When the actuator piston is actuated by compressed gas,the valve opens or closes,and the double-acting form relies on compressed gas to control the valve switch.
