Features:
1) This valve is made of high-quality ductile iron, resulting in a reduction of weight
by about 20%~30% of that of the traditional ones, easy installation and maintenance
2) The valve body is coated with powder non-toxic epoxy resin inside and outside
to prevent it from corrosion
3) The design of three O-type sealing rings used between both valve rod and valve
cover can reduce the frictional resistance at open or close water leakage a great
deal, and the sealing ring can be replaced without stopping the medium flow inside
of the pipeline
4) The elastic-seat enclosed gate valve uses the same design of flat-bottom as that
of the pipeline so as not to be easy to get sundry matters piled up thus making
the fluid smoothly flowing without any resistance
