Features and advantages
Valve plate with a high gradient design, the valve seat is inclined to effectively improve the flow rate of the valve response to the media, the better use of medium flow power and gravity. At the same time, the valve plate truss streamline design, can increase the flow area, reduce the flow resistance coefficient, reduce operating costs.
The unique eccentric pendulum structure and external buffer mechanism;
The valve plate adopts double eccentric swing structure, which is helpful to reduce the flow resistance and vibration;
The unique buffer damping cylinder can effectively control the closing speed of the valve to reduce and eliminate the water hammer.
Fully adaptive flow switch, no plug-in operating system, low carbon environmental protection.
Regardless of the position of the piston, the flow profile is annular, thus ensuring a perfect linear regulation characteristic.
