Gq-wear-free track spherical truncation valve, with its unique structure, the spore rotary separation opening, mechanical pressure sealing new technology design, the most prominent advantage is that the sealing surface does not produce friction, long service life, low operating torque, even if the medium contains solid particles, sediment, short fiber and other impurities, fluid medium high-speed concentrated erosion of the seal body and other harsh conditions, It can maintain a good seal to ensure safe and reliable operation during the maintenance period of the engineering device.

GQ- non-wear track spherical cut-off valve, replacing the traditional gate valve, globe valve, ball valve and plug valve and other cut-off valves, widely used in petroleum, natural gas, chemical, pulp and paper, power station, steel mill, environmental protection sewage treatment and other industries. Valve body, valve cover, valve stem, CAM, valve core, sealing pair and other main parts, select different material groups, can meet a variety of working conditions. It can also be designed and manufactured according to the working conditions of fluid medium, pressure, temperature, connection size and so on provided by the owner.

Switch without wear:

The ball core deviates from the seat and then rotates to eliminate the friction of the seat, which solves the problem of seat wear of traditional ball valve, gate valve and plug valve.

Hard sealing surface of anti-wear spool:

The surface of the ball core is surfacing with a hard polished sealing surface to ensure the sealing performance under very harsh working conditions.

Top mount design:

After the system is decompressed, it can be checked and repaired online to simplify maintenance.

Low torque operation:

Can be equipped with small wheel (unless oversized caliber), and no gearbox is required. Because the spherical cut-off valve sealing surface is frictionless, it is particularly easy to turn, which means that an economical drive device can be used while ensuring sufficient drive thrust to open and close the valve.。

Optimal flow characteristics:

Both full and standard diameters have high Cv values, enhancing the pump's system efficiency. And minimize the abrasion problem.

Double stem guide pin:

The rigid stem guide groove and guide pin control the lift and rotation of the valve stem.

Easy to clean:

When the ball core tilts away from the seat, the fluid will wash the debris in the sealed area along the sealing surface 360 degrees.

Mechanical wedge seal:

The CAM bevel at the lower end of the valve stem provides a mechanical wedge tightening force to ensure adequate seal pressure.

Long life:

Spherical cut-off valves will replace ball valves, gate valves, globe valves and plug valves that are prone to failure. The unique performance of its valves will reduce plant parking and reduce costs for owners.
