Metal to Metal Ball Valve

Specification parameters

Design Specification:

Product Introduction:

The material of the metal to metal ball valve seal pair (ie the seat seal face and the ball seal face) is paired with a metal to metal ball valve. The structure of the ball valve is divided into a floating ball type and a fixed ball type, and the connection form is a flange connection, a welded connection and a screw connection. Product seals can be divided into the following two types:

1) One-way seal: It can only be sealed in the specified direction, that is, the sealing direction indicated by the ball valve.

2) Two-way seal: seals in both directions.

Hard-sealed ball valve, manual cast steel hard seal ball valve body surface adopts advanced spraying technology, through the treatment of various working conditions, the highest hardness can reach HRC78. The seat sealing surface is treated to a maximum hardness of HRC72. The ball and the valve seat are paired and ground, and all sealing areas of the entire sealing surface of the ball valve are precisely ground. Suitable for high temperature and high pressure water, steam, petroleum, coal, fiber, thick and corrosive media, and media with particles. The metal sealing ball valve has a floating ball and a fixed ball. The two metal seat rings are in contact with the spherical surface, and the valve seat ring and the spherical surface are sealed by a uniform spring load acting on the seat ring. Due to the spring load, the auxiliary seal expands to achieve the seal between the valve body and the valve seat. The spring load is sufficient to provide a reliable seal between the valve seat and the ball. Under low pressure conditions, it can be designed between the seat sealing surface and the ball. There is a sealing grease injection system.
