Stainless Steel Check Valve Application:
Valve is used for preventing the back-going of medium in pipelines and equipments, and the pressure of
medium will bring the result of opening and closing automatically.
When the medium is back-going, valve disc will automaticaly closed to avoid accidents.

Types of Valves
The type of disk will decide the type of valve. Most common types of Check valves are
Dual Plate Type
Stop Check Valve
Swing Check Valve
The disc in a swing type valve is unguided as it fully opens or closes. This Valve operates when there is flow
in the line and get fully closed when there is no flow. Turbulence and pressure drop in the valve is very low.
Disk and seat designs can be of metal to metal or metal to composite.
The angle between the seat and the vertical plane is known as the seating angle and varies from 0 to 45 degrees.
Usually, the seat angles are in the range of 5 to 7 degrees. Larger seat angles reduce the disc travel, resulting in
quick closing, thus minimizing the possibility of water hammer. A vertical seat has a 0-degree angle.
The swing type valve allows full, unobstructed flow and automatically closes as pressure decreases. Usually installed
in combination with gate valves because they provide relatively free flow combinations.
A basic swing type valve consists of a valve body, a bonnet, and a disk that is connected to a hinge.
We choose suitable wood cases according to different valves and arrange skilled workers to pack in case of bruise. Long term cooperated forwarder will book space, clear customs and transport for us without delay. There are three ways for transportation, by sea, by air and by train. We will arrange transportation according to customers' needs.
