    What is a BS resilient seated gate valve?

    BS resilient seated gate valve is a new type of valve equipment. It is characterized by the use of soft materials such as rubber rings between wedge discs and seats to achieve sealing. Compared with the traditional hard and densely sealing valve, the sealing and performance have obtained a lot promote. The soft sealing gate valve provides a tightening force through high quality spring and pressure plates, so as to achieve a better sealing effect. It can adapt to different working environments and needs. The soft sealing gate valve has the advantages of sealing reliability, long service life, and energy saving and consumption reduction. It is widely used in the fields of power stations, pharmaceuticals, chemicals, and sewage treatment. Due to the sealing ring of the soft sealing gate valve is made of high elastic materials, it has long service life and it is also helpful to reduce maintenance costs.

    Advantages of BS resilient seated gate valve:

    1. Overall rubber coating

    The overall coating of the inside and outside of the disc is used with high quality rubber, and the domestic leading rubber vulcanization technology is used to keep the valve that maintains accurate geometric size. More importantly, the high stickiness between rubber and disc sticks the rubber stably together and has good elastic memory.

    2. Strong corrosion resistance

    The valve body is coated with epoxy resin powder to prevent the valve from corrosion and rust, and the valve can be used for the wastewater system. It is difficult to break, and the traditional gate valve has broken due to the impact or collision of other objects. The new valve body material is ductile iron, which significantly reduces the broken condition of this material.

    3. Non -toxic epoxy resin coating

    Due to the internal and non -toxic epoxy resin coating inside the valve body, the surface of the inside and outside of the valve is completely covered with rubber, rust or corrosion will not occur, which ensures that the water can drink.

    4. The valve body uses precision casting

    The valve body is made of precision, and the precise geometric shape makes it possible to ensure the sealing of the valve without any other processing inside the valve.

    5. Better sealing performance

    The soft sealing gate valve uses soft materials such as rubber to achieve sealing between the wedge disc and the seat. The sealing effect is better, it can adapt to a complex environment, and has higher sealing reliability and service life.

    6. Lower maintenance costs

    The sealing ring of the soft sealing gate valve is made of high elastic materials. It has a long service life and can save more maintenance costs. At the same time, the valve body is made of ductile iron. The weight is about 20%to 30% lighter than the traditional valve. It is easy to install and maintain, and can reduce maintenance costs and time.

    7. Smaller traffic noise

    The material of the soft sealing gate valve can effectively reduce the flow noise of the fluid through the valve, make it work more stable, and be suitable for occasions with higher requirements for flow noise.

    Quality control process

    quality control process

    Standard Test


    Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.


    Seat Test: 1.1 times the working pressure with water.


    Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.


    Special Test: On request, any other test can be carried out according to special instruction by client.
