Deep cooling top mounted ball valve
Text description:
Product Introduction:
The integrated top mounted structure design of the valve body and the use of finite element calculation to extend the height of the valve cover meet the requirements of BS6364 and MESC 77/200; DBB and DIB structural design can achieve bi-directional sealing and automatic pressure relief of the valve seat in the valve chamber; Design of valve stem anti blow out, fire and anti-static, and micro leakage structure; Low torque, maintenance free, and long service life.
