A forged steel hard-seated ball valve is a high-performance valve that utilizes metal sealing rings for a hard-to-hard seal on the valve seat. Its core components include the valve body, cover, stem, ball, seat, and sealing ring, which are actuated by rotating the ball to open or close the valve. The sealing surfaces of the ball and seat are fully sealed in a metal-to-metal manner, ensuring reliable sealing under various temperatures and pressures through high-precision machining and special hardening treatment.

Structural Features

The structural features of the forged steel hard-seated ball valve include:

High precision machining: The spherical surface is treated with advanced techniques such as mirror polishing or ultrasonic喷涂, ensuring smoothness and durability of the sealing surface.

Metal Sealing: Valve seats and spheres are made of metal, with surface hardness enhanced through hardening techniques (such as hypersonic spraying, nickel-based spray welding, etc.) to exceed HRC60, even reaching HRC74 or higher.

‌Multiple Connection Methods: Normally法兰 connections are used, but socket welding connections are also available, catering to various installation requirements._

Application Scenario

Forged steel hard-seated ball valves are widely used in various industrial fields, particularly excelling in the following scenarios:

Petroleum, Chemicals, Power: Used for oil and gas pipelines, refining equipment, chemical reactors, etc.

Environmental Protection, Water Conservancy, Heating: Used for wastewater treatment, water treatment equipment, heating systems, etc.

Mechanical Manufacturing: Ideal for controlling a variety of fluid mediums, particularly excelling under demanding conditions that involve solid particles and slurry.
