Product features:
1、Using floating valve seat, two-way cut-off, reliable sealing. Seat internal lip gasket, low-pressure sealing and fire protection.
2、Gate and valve body have fine machining of the guiding mechanism, while the sealing surface are spray welded carbide, erosion resistance.
3, due to the floating seat and fine processing of the guiding mechanism, so that the valve opening and closing torque compared to ordinary gate valve reduced by half, can easily operate the valve opening and closing.
4, the flow path is straight-through, fully open when the flow path and the gate guide hole through, and the size of the same and straight pipe, flow resistance is very small.
5、The valve stem adopts packing multiple sealing, which makes the packing compression uniform, reliable sealing and small friction.
6, all-weather design, drive mechanism are designed with waterproof and dustproof device, good protection performance.
