Gate valve has the characteristics of small fluid resistance, applicable pressure, temperature range, etc., is one of the most commonly used cut-off valve, used to cut off or connect the medium in the pipeline. The diameter shrinkage can reduce the size of the parts, reduce the force required for opening and closing, and expand the application range of the parts. However, the fluid resistance loss increases after the diameter shrinkage. The low pressure gate valve in China is generally made of cast iron, which often has serious problems such as body freezing cracking and gate plate falling off. The carbon steel stem of cast iron gate valve is easy to rust, the packing gasket is of poor quality, and the internal and external leakage is serious. PN10 low pressure carbon steel gate valve produced by Shanghai Hugong Valve Factory replaces the traditional iron gate valve, effectively solves the problems such as the shell of cast iron gate valve is easy to freeze and crack, the gate plate is easy to fall off, the valve stem is easy to rust, and the sealing performance is not reliable.

1, light weight: the body is made of high class ball black cast iron, the weight is about 20%~30% less than the traditional gate valve weight, easy installation and maintenance.

2. Overall packaging: the gate adopts high quality rubber for overall internal and external rubber. The European first-class rubber vulcanization technology ensures the precise geometric size of the vulcanized gate, and the rubber and ductile casting ram are reliable, not easy to fall off and have good elastic memory.

3, flat type brake block: traditional gate often wash the tube in the water after the external objects such as stone, wood, cement, iron filings, sundry sedimentation on the bottom of the valve such as the slots, easy to cause cannot close tightly and form slack phenomenon, at the bottom of the seal of the elastic base seat gate valves with water pipe with flat design, not easy to cause debris deposition, make the flow unimpeded.

4, investment casting valve body: the valve body adopts precision casting, precise geometric size makes the valve body without any finishing can ensure the sealing of the valve.
