CS SS Control Ball Valve with Soft Seated and Metal Seated Low Torque Large Flow Capacity

Electric V type eccentric control ball valve

ZDRVE Series eccentric ball valve uses a special eccentric structure. It has a compact structure, well-sealed and a long service life; and compatibility of regulating and shut-off functions. It is especially applicable to the fluids such as paper pulp, sewage and other fluids containing fibers and grains, which are widely used to cut off or regulate the processing fluids in industries such as chemical, electric power, and paper making.

PN(MPa):1.6,4.0,6.4,10.0(150lb,300lb,600lb)；

DN(mm):25～400(1”～16”)；

Temperature；-60～+450℃；

FEATURES:

l   The body adopts the integrity casting technology which achieves compact structure, small volume, good pressure resistance；

l   V port eccentric assembly: when closed, the ball will produce a eccentric force to press on the sealing ring to achieve the best sealing performance; when opened, the ball separate from the sealing ring in order to prevent damage on the sealing ring.

l   Adopt soft seated and metal seated to satisfy different working condition; Sealing surface overlay with titanium alloy can be used in harsh conditions;

l   The operation torque is greatly been decreased because of the eccentric structure and greatly increased the allowable pressure.

l   Adopt special surface treatment to improve the wear resistance and erosion resistance and service life; 

l   Large flow capacity, adjustable ratio reaches 100;

l   There is a shearing action between the ball and sealing ring in the moment of closing, which could shut-off the medium fiber and extrusion particulate matter. It is especially suitable for pulp and paper, sewage and other media containing fiber and particulate matter as well as for general medium;
