Forged Steel Internal Threaded Socket Gate Valve

Product Name:Forged Steel Internal Threaded Socket Gate Valve

Model No.:Z61H-1500LB

---

Brief introduction:

The opening and closing part of Z61H forged steel gate valve is the valve disc. The movement direction of the disc is perpendicular to the direction of the fluid. That gate valve can only be fully opened and fully closed, and cannot be used to adjust the flow or throttle; there are two sealing surface on the disc, for the most used gate valves, that two sealing surfaces form a wedge, and the wedge angle degree varies with the valve parameters, usually its 50, and 2°52′ when the medium temperature is not too high.

Characteristics:

1. Small flow resistance, the sealing surface is less washed and eroded by the medium.

2. Energy saving for opening and closing.

3. The flow direction of the medium is not restricted, without disturbing the flow and reducing the pressure.

4. Simple shape, short face to face length, good manufacturing technology, wide application.

Applications:

This gate valve can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipbuilding, metallurgy, energy and other industrial pipelines to adjust and cut off the mediums.
