The type of regulating valve suitable for small pressure conditions, close tight, suitable for medium flow or pressure regulation.
810D top guide type single seat control valve, the top guide not balanced structure and has high strength, heavy load, an S-shaped channel, pressure drop, flow coefficient, can adjust in a wide range, flow characteristics of high precision. This type of adjustment valve is suitable for the condition of small pressure difference, close the tight, suitable for the adjustment of medium flow or pressure.

Product features
The valve seat is made of screw in structure, has the advantages of reliable performance, convenient replacement and maintenance, etc.,  to solve the problem of the traditional no valveseat body leakage can not be replaced. Extended service life. The open design, the media tendsto open the valve opening direction, good controllability,flow characteristics and small distortion,According to the working condition, the electric or pneumatic actuators can be controlled.
