Product Description

The Valve Seat is one of the key components in the valve and plays a vital role.

The valve seat is usually located inside the valve body, closely matched with the spool, and its main function is to achieve the sealing of the valve. When the valve is closed, the seat and the spool push against each other, preventing fluid from passing through, ensuring the tightness of the system and preventing leaks. The sealing performance of the valve seat directly affects the reliability and service life of the valve.

Valve Seat materials are varied, common metal materials such as stainless steel, cast iron, and non-metallic materials such as rubber, plastic and so on. Different materials are suitable for different working environments and fluid media. For example, the metal seat has high strength and corrosion resistance, which is suitable for high temperature, high pressure and strong corrosion occasions; Non-metal seat has good elasticity and sealing, suitable for some low-pressure occasions with high sealing requirements.

In design, the shape and structure of the seat also vary. There are plane seat, cone seat, spherical seat and other forms. Each form has its own unique advantages and scope of application. For example, the sealing performance of the cone valve seat is better and can withstand higher pressure; The spherical seat has the feature of automatic alignment to ensure a good fit between the spool and the seat.

In order to ensure the proper operation of the valve seat, regular maintenance and maintenance are required. This includes checking the sealing performance of the seat, cleaning the seat surface, and timely replacement of severely worn seats. Only in this way can we ensure the reliable operation of the valve and extend the service life of the valve.
