Pressure Balance Plug Valves
Key Applications
- For systems of petrochemical, chemical, natural gas, LPG, gas, HVAC, food and pharmaceutical industries.
 
Design Features
- Sizes from NPS 2” to 24”(DN50 to DN600)
 - CLASS 150 to 1500 (PN20 to PN260)
 - Operating temperature -46℃ to 120℃
 - The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve
 - The important feature of plug valve is that it is adaptive to multi-passage structure, so one valve can have two, three or even four flow passes.
 - Quick opening and closing, small flow resistance, and fast angular travel operation
 - The medium can flow in two directions, facilitating unlimited mounting direction and online repair.
 - Small switching moment, reliable sealing
 - Reversed plug design, the higher the pressure is, the better the sealing performance is.
 - Emergency injection function of valve stem
 - Injection hole and channel are provided on the valve body for injecting stop-leak compound between sealing faces.
