Pressure Balance Plug Valves

Key Applications

For systems of petrochemical, chemical, natural gas, LPG, gas, HVAC, food and pharmaceutical industries.

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.
