Gate Valve Research: What Are Its Characteristics

Gate valves are one of the most commonly used globe valves for shutting off or connecting media in pipelines.

Gate valve reduction can reduce the size of the parts, reduce the force required to open and close, and expand the range of application of the parts. However, the diameter is reduced, the fluid resistance loss increases.

Domestic and foreign low-pressure gate valves are commonly used cast iron materials. Cast iron gate valves often have serious problems such as freezing and cracking of the valve body and dislodging of the gate. Cast iron gate valve carbon steel stem is easy to rust, packing gasket quality is poor, and internal and external leakage is serious.

LIWEI valve factory uses ductile iron to replace the traditional iron gate valve, which effectively solves the problems of cast iron gate valve casing easy to freeze and crack, gate plate easy to fall off, valve stem easy to rust, unreliable sealing performance, etc.

More features of the gate valve.

1、Light weight: The valve body is made of high-grade ductile iron, which is about 20%~30% lighter than the traditional gate valve. It is easy to install and maintain.

2、Whole package rubber: The inner and outer rubber of the gate is made of high quality rubber. The first-class European rubber vulcanization technology makes the vulcanized gate ensure accurate geometry, the rubber is firmly connected with the ductile iron gate, not easy to fall off, and good elastic memory.

3、Flat bottom gate valve seat: Traditional gate valve is often deposited in the groove at the bottom of the valve due to stones, wood, cement, iron chips, debris and other foreign objects after washing the pipeline, which easily causes water leakage.

The bottom of the resilient seat seal gate valve adopts the same flat bottom design as the plumbing machine, which is not easy to cause debris siltation and make the fluid flow unobstructed.

4、Precision casting valve body: the valve body is precision cast, the precision geometry makes the valve body without any fine processing inside, to ensure the sealing of the valve.

5、Small fluid resistance: Because the medium channel in the gate valve body is straight, the medium does not change the flow direction when flowing through the gate valve, so the fluid resistance is small.

6, opening and closing torque is small, opening and closing more effort. Because the gate valve opening and closing the gate movement direction is perpendicular to the direction of media flow, so the gate valve opening and closing more labor-saving

The grooved gate valve [1] adopts a top-mounted structure, which reduces the connecting bolts of the valve body under the conditions of high pressure and large diameter, enhances the reliability of the valve and can overcome the influence of the weight of the system on the normal operation of the valve.
