650 degrees high temperature ball pneumatic valve how to select material is appropriate

the highest temperature degrees high temperature pneumatic valve ball ability to °, pneumatic valve body material for cast steel ( ） , the ball is ( Spray welding) , sealing material for carbide hardness can reach - 。 The company adopts single seal structure: with graphite sealing, the other side using the pneumatic spring seat and the ball to the opposite, this design makes the pneumatic valve switch is very light, and the sealing performance is very good also. So the benefits of the product, wear-resisting, high temperature resistant, light switch, long service life.
degrees high temperature pneumatic ball valve features:
advanced sphere and pneumatic seat hardening technology degrees of high temperature ball sphere of pneumatic valve and pneumatic seat completely use a metal to metal seal, in order to ensure reliable pneumatic valve under various temperature and pressure seal, in view of the different operating conditions and requirements of users, you can use a variety of advanced sphere and pneumatic seat hardening technology, including spray supersonic spraying, nickel-based welding, special surface hardening, hard alloy spray welding and using high strength and high hardness of the ceramic material, such as a sphere and pneumatic valve seat surface hardness can reach more than HRC commonly, up to more than HRC. Sealing surface material heat resistance can reach ℃, the highest can amount to ℃. Material bonding strength can reach above PSI, sealing surface material also has the very good properties, such as friction resistance, impact resistance. Degree of high temperature ball pneumatic valve can be applied to the vast majority of harsh working conditions. Prevent pneumatic valve in the heat of death under the working condition of high temperature rise caused by thermal expansion and easy to sphere with pneumatic seat up to death, leading to a pneumatic valve cannot open. Degrees of high temperature ball pneumatic valve adopts the sealing structure of disc spring or spring loaded, parts under high temperature thermal expansion can be absorbed by disc spring or spring, so can ensure the pneumatic valve will not be up to death, at high temperatures and be able to flexibly opening and closing at high temperature. Degree of high temperature ball pneumatic valve excellent seal performance using unique ball grinding process, through the sphere and the rotation of the grinding apparatus in different space position, make a sphere surface to achieve high roundness and roughness, pneumatic valve sealing performance fully meet or exceed standards.
