Product Introduction

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 dense 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 being made of highly elastic materials, it has a long service life, and it is also helpful to reduce maintenance costs.

Advantages of BS resilient seated gate valve!

  • 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.

  • 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 impact or collision with other objects. The new valve body material is ductile

    iron, which significantly reduces the broken condition of this material.

  • 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.

  • 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.

  • 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.

  • Lower maintenance costs

    The sealing ring of the soft sealing gate valve is made of highly 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.

  • 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.
