1. For V type ball valve, the bevelling spring or pillar spring loaded movable seat design has been employed, which is reliable in seal and of long service life as there in no such problems as clenching or disjointing.

   2. It features the function of slipping between the ball with cutting edge and metal seat, which is particularly suitable for the medium containing fibre, solid particles, thick fluid, and so on.

   3. As per different working conditions of customers, several kinds of advanced techniques have been employed separately for the ball and seat surface of metal to metal sealed ball valve, such as nickel base alloy by spraying welding (for hardness ≥HRC60),stellite alloy by ultra-sonic spraying coating (for max.hardness ≥ HRC70) , and specially hardened material etc., which are suitable for many kinds of critical working conditions.

   4. When the valve is fully open, flow capacity is big, pressure loss is small, and the medium would not deposit in the body cavity.

   5. Being impact in structure and extensive in common use, the cutting off V type ball valve features perfect sealing property and may replace gate valve, globe valve and general ball valve . For regulating V type ball valve, its regulating scope available is wide, and its regulating accuracy is high.
