The half-ball valve is manufactured with flange sealing surface according to the concave-convex flange technology stipulated in GB/T 9113.2--2000.

Half ball valve is a kind of practical operational products, the actuator is equipped with hydraulic actuators, more portable, easy to use remote automation, developed the half ball valve application scope, especially in the bad environment is not convenient and manual operation or normally open action, form a complete set of automated computer operation cases, half a ball valve, more opened new ideas.

The half-ball valve has the characteristics of small opening force, closing can break the barrier of scaling, good sealing performance and wear resistance. Half ball valve wear-resistant corrosion material, so it is widely used in water, steam, sewage, petrochemical, natural gas, solution and pulp and other two phase media, and dust gas and other ideal transmission equipment.
