- For systems of petrochemical, chemical, natural gas, LPG, gas, HVAC, food and pharmaceutical industries.
- Sizes from NPS 2” to 12”(DN50 to DN300)
- CLASS 150 to 1500 (PN20 to PN260)
- Operating temperature -46℃ to 120℃
- The sealing faces of the valve seat and valve clack are hard faced with alloy to improve the erosion resistance and extend the service life of the valve.
- Double cut-off and double fail-safe effect and switchover use, facilitating longer service life
- Can replace the cascade installation of two valves and reduce the leaking points.
- 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.
