ANSI Bellows Gate Valve

ANSI Bellows Gate Valve

Introduction:

The opening and closing parts of the corrugated pipe gate valve are plug shaped valve clack, the sealing surface is flat or conical, and the valve clack moves in a straight line along the centerline of the fluid. The movement forms of the valve stem include lifting rod type (the valve stem rises and falls, and the hand wheel does not rise and fall) and lifting rotary rod type (the hand wheel and the valve stem rotate together to rise and fall, and the nut is set on the valve body). The corrugated tube globe valve is only applicable to full opening and full closing, and is not allowed to be adjusted or throttled. This type of valve shall be installed horizontally in the pipeline.

Benefit:

Simple structure, easy to manufacture and maintain.
The working stroke is small and the opening and closing time is short.
Good sealing performance, low friction between sealing surfaces, long service life.
The disadvantages of bellows gate valves are as follows:
The fluid resistance is large, and the force required for opening and closing is large.
It is not applicable to medium with particles, high viscosity and easy coking.
Poor regulation performance.
