Advantage
The soft-seal gate valve overcomes the defects of general gate valve such as
poor sealing, fatigue, and easy rust. The soft sealing gate valve is a
replacement product of the traditional gate valve. It uses the compensation
effect of the elastic gate plate to produce a small amount of deformation to
achieve a good sealing effect. The valve has the obvious advantages of light
switch, reliable sealing, good elastic memory and long service life, and can be
widely used It is used as a regulating and intercepting device on fluid
pipelines such as tap water, sewage, construction, food, electricity, medicine,
metallurgy, textiles, energy systems, etc.
 
Features
1. Flat-bottomed seat
The traditional gate valve is often caused by foreign objects such as stones,
wood blocks, cement, paper scraps, debris and other sludge accumulated in the
bottom groove of the valve after the pipe is flushed with water. The bottom of
the soft-seal gate valve adopts the same flat-bottom design as the water pipe,
which is not easy to cause debris siltation and makes the fluid flow unimpeded.

2. Overall encapsulation
The valve adopts high-quality rubber for integral inner and outer rubber. The
domestic first-class rubber vulcanization technology enables the vulcanized
valve to ensure accurate geometric dimensions, and the rubber and ductile
iron valve are firmly connected , not easy to fall off, and have good
elastic memory.

3. Corrosion resistance
The valve body is coated with powder epoxy resin to prevent corrosion and rust
of the valve body. It can also be used in sewage systems. Not easy to break.
In the past, traditional cast iron gate valves often broke due to foreign
objects hitting, colliding or overlapping. Due to the use of nodular cast iron
for the body, this situation has been greatly reduced.

4. Three "O" type
Because the valve stem adopts three "O" ring seal ring design. It can reduce
the frictional resistance when switching, greatly reduce water leakage and can
replace the sealing ring without stopping the water.
