High temperature forged gate valve （Description）

Z60Y, Z61Y, Z62Y high temperature and high pressure power station gate valves follow the same temperature and pressure grade, there is a certain interchange relationship in some pipelines. The middle part adopts the pressure self-tightening type without valve cover, which has good sealing performance under high temperature and high pressure. The self-sealing ring has two materials, one is low carbon steel, the other is flexible graphite 316 wire (mesh). The sealing surface is welded with drill base cemented carbide, and the pure metal layer after processing is ≥3mm. It has wear-resisting, high temperature resisting, corrosion resisting, abrasion resisting and long service life. Both ends of the branch pipe are welded structure, welding according to the groove can be made according to the standard or user requirements. Suitable for thermal power plants, petrochemical, metallurgy and other high temperature and high pressure water, metallurgy and other high temperature and high pressure water, steam, oil, superheated steam pipelines.

Structural features

1、There is no valve cover pressure self-tightening connection in the middle

2、The gate is wedge type elastic single gate or wedge type double gate structure

3、Gate/valve seat double face surfacing drill base carbide

4、High temperature creep resistance design

5、The stem is made of nitriding precipitation hardened stainless steel

6、Manual, gear (bevel gear and spur gear) transmission, electric

Product installation and maintenance:

1. Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
2. The double gate valve should be installed vertically (that is, the stem is in the vertical position, the handwheel at the top).
3. Gate valve with bypass valve should be opened before opening the bypass valve (to balance the pressure difference between inlet and outlet and reduce the opening force).
4. The gate valve with transmission mechanism shall be installed according to the provisions of the product manual.
5. If the valve is often used, at least once a month lubrication.
