Working principle:

The ball and seat of the Metal seated floating Ball Valve adopts a metal-to-metal sealing method. In order to ensure the reliable sealing of the valve at various temperatures and pressures, according to the different operating conditions and requirements of users, a variety of advanced The hardening technology of the sphere and valve seat includes supersonic spraying, nickel-based spray welding, special surface hardening, cemented carbide spray welding, and the use of high-strength and high-hardness ceramic materials. The surface hardness of the sphere and valve seat can generally reach HRC60 or more, the highest It can reach above HRC74. The temperature resistance of the sealing surface material can reach 540℃, and the highest temperature can reach 980℃. and the sealing surface material also has good abrasion resistance and impact resistance. The metal hard seal ball valve can be suitable for most of the harsh working conditions.

Product features

1. It has fire-proof and anti-static function.

2. The handle and the valve stem are connected in a flat square shape. A locking structure can also be added as needed to prevent wrong operation.

3. It adopts a bottom-mounted valve stem and an inverted sealing structure to ensure reliable sealing at the packing and prevent the valve stem from coming out.

4. The valve seat adopts a cylindrical spring and a metal hard seal structure, which can be adapted to higher temperatures and various dust and solid particle media.
