DIN flanged check valve
DIN Check valve are used in various industries such as petroleum, water, steam industry etc under nominal pressure of PN1.6~PN4.0Mpa and working temperature of -20~450 degrees.

Check valve can stop fluid from backflow. The disc opens by the pressure of the fluid and the fluid flows from access to exit. When the accessis lower than the exit, by pressure differential and gravit, disc will shut automatically to stop the backflow.

Vertical check valve and globe valve has similar structures. The disc does vertical movements around the certerline. Its movement is reliable. Check valve usually applys to horizontal pipline only.

Features:
1. This product has logical structure, reliable seal, excellent performance and nice design.
2. The stem srface is build-upwelding with Co hard alloy, which is attrition-resistant, corrosion resistant has god friction resistant and long life.
3. The part material, flange and butt weld and dimension may be selected accordng to current operating condition and users' requirement, so that meeting the requrements of various engineering.
