Characteristics:

Switching on the full port, the loss of head is zero.
The most reliable sealing method with self-sealing.
The hard sealed half ball valve can cut debris.
Sand abrasion-resistant.
Open and close quickly, rotating the eccentric crankshaft by 90 degree will open or close quickly.
Direct access to the flow, the strongly eccentric crankshaft makes it adapted to high velocity with no vibration.
The rubber covered on the spherical crown is wear and anti-aging, the eccenter avoids the abrasion between
spherical crown and the seat, and extends the life.
Installation height is short, less than half of that of the gate.

Profile:

Eccentric half ball valve is the fastest growing valve in occident, simple but reliable structure and effective sealing make it able to take the place of gate valve and butterfly valve and even those circumstances when gate and butterfly valves can not be used.

The hard seal eccentric half ball valve is a crystallization of traditional ball valve's being full of spiritual change, it fixes the metal ball crown on the eccentric crankshaft, realizing opening and closing the valve by the 90-degree rotation of the eccentric crankshaft. Contacted with the sealing surface of metal ball crown, the metal seat floats in the axial and radial, in order to compensate the mismatch error between the ball crown and seat.
