Product Detail

Forged High-Pressure Ball Valve: Definition, Fire-Resistant Function, Parameters & Features

1. Definition

All components of the forged high-pressure ball valve are forged parts. The soft sealing ring is embedded in the steel ring, and the steel seat is also machined with a sealing surface. O-rings are installed on both the radial and back sides of the steel seat to ensure no medium leakage. The valve stem adopts a bottom-mounted design, and a thrust bearing is installed at the shoulder to reduce the operating torque.

2. Fire-Resistant Function

Once the soft seal is burned out, the medium pressure pushes the ball against the steel seat, which can achieve the fire-resistant function. This structural design, combined with the all-forged components and multi-position O-ring sealing, ensures sealing reliability even in case of accidental fire, avoiding medium leakage and ensuring system safety.
