SEHO Electric High Pressure Ball Valve

SEHO electric high pressure ball valve is composed of ***1R angular travel electric actuators and
*-piece high pressure ball valve body assembly. The trim adopts trunnion mounting ball. Due to
specialized optional metal to metal sealing or to nonmetal sealing material combination ,it can
guarantees excellent conveying and shut-off performance against process fluid which being at
***6℃～**0℃ working temperature and up to **0Kg/cm2 working pressure.
SEHO Electric High pressure Ball Valve is characterized by compact structure, effective handle
and long lifetime. It can be widely used in oil, chemical, power station, paper and pulp,
metallurgy , sewage treatment etc. processing industries to control high pressure or high pressure
drop fluid, especially suitable for the fluid entrained with fibre or particle.
