Heating Dedicated Fully Welded Ball Valve
Product overview
Heating dedicated full welded ball valve body by the steel sheet forming, the compound, and avoid any possible medium leakage phenomenon, the spring loaded valve seat combination structure, adaptable to the pressure and temperature changes, to ensure that the sealing ring closely contact with the sphere, on the premise of ensuring seal valve opening and closing flexible, convenient operation, ball and stem are precision machine tool and reduce the friction coefficient between the contact surface, further improve the valve's sealing performance and operating torque. The products are widely used in the fields of natural gas, oil, heat supply, chemical industry and thermal network.
Product Features
Heating dedicated fully welded ball valve with fixed ball structure, the sphere of the upper and lower shaft with bearings, operating torque is small, the structure of the ball is fixed, no movement after compression, the design has two sealing rings provide enough preload force to ensure the sealing, double seal, the sealing per-formance is more reliable. The processing of the ball has an advanced computer detector tracking test, with high precision of the ball. As the body material is the same as the pipe material, there will be uneven stress, which will not cause deformation Because the body material as pipe material, won't appear uneven stress,also won't appear due to earthquake and the vehicle through the ground deformation, occurs when the seal ring ontology with 20% C (carbon) content of PTFE materials, guarantee completely without leakage (0%).
