Product Features:

Compared to PFL series valves, this valve features a pre-valve sealing structure with sand-proof function, suitable for fracturing and sand injection operations. It utilizes an enclosed structure with inner and outer valve seats, and through hydraulic assisted sealing, the middle cavity remains unpressurized during opening and closing, preventing oil, gas, mud, and fracturing sand from entering the valve cavity, thus extending the valve's service life. The valve plate and seat can be repaired online without special tools. Metal seals are used between the valve plate, valve seat, valve body, and valve cover.  Available in manual and actuated versions; actuators include hydraulic cylinders, gearboxes, or electric actuators.
