Valve trim with improved durability by shock absorbing layer Valve Trims by Prohibiting Scale Attachment and Improving Durability
Application
Manufacturing technique extending the life of valve applied to harsh condition of high temperature & high pressure fluid
- Maintain long life of valve trim by shock absorbing layer and durability
- Prevent clogging from valve trim thanks to low friction coefficient by nano coating
- Prevent sticking of valve moving part thanks to high hardness surface by nano coating
- Maintain the system stability by blocking the leakage on the sealed part by shock absorbing layer
Assembly
Plug stem
Seatring
Cage
