YDAOX43 track cock valve (general valve) is suitable for cutting off or connecting pipeline medium in various working conditions of petroleum, chemical, pharmaceutical, fertilizer and electric power industry at nominal pressure CLASS 150-900LBS and working temperature - 29-180 C.

Main structural characteristics

1. The product is reasonable in structure, reliable in sealing, excellent in performance and beautiful in appearance.

2, its sealing is achieved through the sealing ring around the valve plate. Unique dovetail groove protection and fixed sealing ring.

3, two-way flow, installation and use more convenient.

4. Material and flange size of parts can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.

Working principle

When the valve is fully open, the plug channel aligns with the valve body channel to ensure the desired minimum pressure drop.

When the hand wheel is rotated, the plug will rotate in the direction of the valve and drive the valve disc to rotate 90 degrees. When the hand wheel continues to rotate, the plug will press down so that the valve opens to both sides and the disc will press tightly against the seat to close the valve.

When the handwheel rotates in the opposite direction, first move the plug upward, so that the valve disc is detached from the seat, continue to rotate the handwheel, so that the plug drives the valve disc to rotate 90 degrees, and finally the plug channel is aligned with the valve body channel, so that the valve is in a fully open state.

The advantage of the valve is that in the process of opening, the valve disc and the valve seat are in a state of detachment, the process of switch is zero friction, will not make the sealing surface wear, and the seal adopts soft seal, so that the seal is zero leakage when closed.
