The elastic seat sealing valve with opening indication is a replacement product of traditional gate valves. It uses an elastic material gate plate and compensates for the slight deformation caused by the elastic material to achieve good sealing effect.

The elastic seat seal with attached opening indication has significant advantages such as lightweight switching, reliable sealing, good elastic memory, and long service life. It is widely used as a regulating and intercepting device in fluid pipelines such as tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems, etc.

The elastic seat sealing gate with attached opening indication is used in the fire protection system. If the installation position of the soft seal gate valve is high above the ground, a rising stem gate valve is generally used to clearly indicate the valve opening. If the installation position is low, an attached opening indication gate valve is required.

The elastic seat seal with opening indication is commonly used in automatic sprinkler fire pipeline systems to monitor water supply pipelines and remotely indicate valve opening. Rising stem gate valves and gate valves with opening indication are also commonly used in fire protection systems. If the installation position of the gate valve is high above the ground, rising stem gate valves are generally used to clearly indicate the valve opening. If the installation position is low, rising stem gate valves can be used. Then it is necessary to attach an opening indicator gate valve.

The operating principle of the elastic seat seal with opening indication:

The valve cannot be used if there is slight deformation or corrosion on the sealing surface of the elastic seat seal with an attached opening indicator, provided that both the body and components are intact. And the repair process is too complicated, causing significant waste. Therefore, in use, there should be minimal friction between the valve plate and the sealing surface to avoid damage to the valve body as much as possible.

After solving the problem of corrosion or deformation of the sealing surface of the valve seat and valve plate, the valve plate can automatically compensate and press tightly against the sealing surface, as well as automatically balance the pressure with the soft seal gate valve. This solves the problem of damage to the sealing surface caused by friction of the soft seal material. Due to the replaceable sealing sleeve of this gate valve, it increases the use of the valve.

During the opening and closing process, the soft sealing material maintains a corresponding distance from the valve seat, allowing the soft sealing material to work in a frictionless and pressure free environment. The sealing sleeve isolates the liquid transported in the pipeline from the components inside the valve core, preventing corrosion and blockage by impurities. The sealing material of this valve is very easy to replace, so its service life is more than 5 times that of general gate valves. Reduced losses and saved resources for the company.

Characteristics of elastic seat sealing with opening indication:

1. The valve stem is equipped with a three O-ring sealing ring, which reduces friction during opening and closing, thereby reducing water leakage. The sealing ring can be replaced without stopping the water supply during construction.

2. The valve body is coated with epoxy resin paint, which can prevent corrosion and rust of the valve body and can be used for drinking.

3. The gate is made of rubber for overall internal and external wrapping, and the rubber vulcanization technology ensures accurate size of the vulcanized gate. The rubber is firmly connected to the ductile iron gate, which is not easy to fall off and has good elasticity.

4. The material of ductile iron can significantly reduce the phenomenon of fracture caused by collision. Due to its casting process, the sealing of the valve body can be achieved without any precision machining, and it is relatively lightweight, easy to install and maintain.
