low-temperature steel used for ball valve

           The low-temperature steel is suitable for alloy applied below 0 ℃. Cryogenic steel or ultra-low temperature steel can be used below -196 ℃. Low-temperature steel mainly has the following performances: (1) Toughness-brittle transition temperature is lower than using temperature(2) Strength meeting the design requirements  (3) Stable organization structure under using temperature  (4) Good weldability and processing-molding performance  (5) Some special applications also require lowest magnetic conductance and cold shrinkage rate.

Three pieces forged steel ball valve

         Three pieces forged steel ball valve can shut tightly only by 92 degrees rotating operation with small rotational torque. Fully equal body cavity provides weak resistance direct runners for medium. ball valves is usually used to open and close, however, 3 pieces forged steel ball valve makes it possible to control the rate of flow.

Ball valve

1. One-piece body, there is no problem in the connection of body and yoke, which effectively improve the valve’s concentricity, allowing reliable connection of stem and ball and stable force in the process of open and close is uniform.
