Product Description

Flange electric ball valve stainless steel high temperature and high pressure steam diesel thermal oil explosion-proof

 

Introduction

Electric flange ball valve is composed of a flange ball valve equipped with an electric actuator. It relies on power drive to operate the opening and closing of the valve and adjust the size of the medium. According to the sealing structure, it can be divided into soft seal and metal hard seal to be suitable for different applications. Among the working conditions and media. It is especially suitable for occasions where the medium is viscous, contains particles and fibers, and is widely used in petroleum, chemical industry, metallurgy, light industry, papermaking, power stations, refrigeration and other working fields.

Key Parts of Ball Valves

Body: The body of the valve, made from stainless steel, is the outer casing and provides the main structure. It contains the internal parts and has connections (ports) for the pipeline.
Ball: The ball is the central component that controls the flow of fluid. It's a sphere with a hole through the middle, which aligns with the pipeline when the valve is open and is perpendicular to it when the valve is closed.
Stem: The stem is the part that connects the handle to the ball. When the handle is turned, the stem rotates the ball.
Seat: The seats are rings of softer material (often PTFE or another plastic) that form a seal between the ball and the body when the valve is closed. There are typically two seats, one on either side of the ball.
Seals: Seals or packing material are used to prevent leakage along the stem. They ensure that when the valve is closed, no fluid can escape.
Bonnet: The bonnet is a part of the valve body that holds the stem. It's often bolted onto the body and provides a seal to prevent leaks.
