Product Overview: 

LXHQ-M1PF Type C Ball Valve (also known as Eccentric Semi-Ball Valve/Type C Eccentric Ball Valve) is a high-performance control valve that combines the sealing of the ball valve with the throttling of the control valve. The valve adopts eccentric hemispherical structure, the ball is separated from the valve seat in the process of opening and closing to realize friction-free opening and wedging sealing in the process of closing. It is suitable for high viscosity, granular, fibrous media and high-frequency opening and closing occasions, and is widely used for flow regulation and cut-off control in papermaking, chemical industry, environmental protection, electric power, metallurgy and other industries. 

Product features: 

Eccentric structure design, no friction in the process of opening and closing, reduce wear, more reliable sealing

Ball with opening notch (C type), with good linear regulation performance, can replace part of the regulating valve application

When the valve is closed, the ball is automatically wedged into the valve seat, the sealing performance is excellent, and the leakage grade can reach Class V ~ VI.

Suitable for slurries, slurries, media with fibers or particles, not easy to block

Compact structure, small opening and closing torque, can be equipped with small actuators to save system cost

Optional metal hard seal/soft seal structure to meet the requirements of different working conditions

Optional explosion-proof, fireproof and anti-static structure to ensure safety in harsh environment

Flexible driving mode, supporting electric, pneumatic and hydraulic automatic control
