Non-rising Stem Gate Valve Product Description

  • Author:RKSfluid Newsroom
  • Release on :2020-03-06
The non-rising stem gate valve to use the nodular graphite casting softly to become, the weight compares the traditional gate valve weight to reduce approximately 20%-30%.The installment service is convenient.
The non-rising stem gate valve to overcome the common gate valve leak-proof quality softly to be bad, the elastic fatigue, easy to rust and so on the flaws. Seals the gate valve is softly the traditional gate valve update product, has the micro distortion compensation using the elastic damper plate, achieved the good seal effect, this valve has the switch to be dexterous, the seal is reliable, elastic memory good and service life long and so on remarkable merit, but widely applies in the running water, the sewage, the building, food, the electric power, the medicine, the metallurgy, spins, fluid pipelines and so in lightly energy system the achievement adjusts and dams the current the installment use.

The non-rising stem gate valve to open shuts is softly the damper plate, the damper plate heading and the fluid direction is vertical, the gate valve only can do all starts with the entire pass, cannot make the adjustment and the throttle.The damper plate has two packing surfaces, But the commonly used pattern gate valve two packing surfaces form, the wedge-shaped angle wedge-shaped along with the valve parameter different, usually is 50, medium temperature between 2° to 52° . The wedge type gate valve damper plate may make a whole, the named rigid damper plate; Also may make can produce the micro distortion damper plate, improves its technology capability, the atonement packing surface angle the deviation which produces in the processing process, this kind of damper plate named elastic damper plate, generally for flange connection.

Soft Seal Gate Valve Features:
1.Flat bottom valve seat
The traditional gate valve is often deposited in the groove at the bottom of the valve due to foreign objects such as stones, wood blocks, cement, paper scraps, and debris after washing the pipe with water. It is easy to cause water leakage when it cannot be closed tightly. The lower part of the soft-sealed gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris deposition and make the fluid flow unobstructed.


2. Overall encapsulation
The valve plate uses high-quality rubber for the internal and external rubber. The domestic rubber vulcanization technology enables the vulcanized valve plate to ensure the geometric size, and the rubber is firmly connected with the ductile iron gate, which is not easy to fall off and has good elastic memory.
3. Corrosion resistance
Concealed soft-seal gate valve body is coated with powder epoxy resin, which can prevent the valve body from corrosion and rust, and can be used in sewage systems.
4. Not easily broken
In the past, traditional cast iron gate valves often hit foreign objects, caused collisions or overlaps and caused fractures. As the valve is changed to ductile iron, this situation can be greatly reduced.
