Long life ball seat:

Seat sealing surface of stellite or other alloy steel, ball sealing surface nit riding treatment or welding alloys, hard

chrome plating, vacuum coating - tungsten alloy stellite and other forms. For all levels of use and high temperature friction dust, slurry, solid class contaminant transport pipeline, with a very high abrasion resistance and long life.

     High precision ball high sealing seat:
     Metal seat, poor sealing of its weakness, the Division I developed a very high metal seal valve seal. Seat by spring preload to ensure tightness, pressure sealing guaranteed by low pressure valve piston effect, one of the most critical is our original sphere process to ensure high precision spheres (roundness). Advanced seat structure, high precision spheres are major factors that constitute tight seal, but also a large and low operating torque.

Wide range of applications in the metal seat:

Generally soft seat, the seat is easy damaged by the half-open state, some fluid can not be used, the temperature range is narrow, limited purpose. Our high hardness of the metal to metal seal valve seat, suitable for high temperature fluid, high friction dust, slurry, containing impacted media, solid foreign substances, etc., almost all of the fluid can be used.

     All the characteristics of both the ball:
     Compare valve, globe valve, has the additional feature of all the features of our metal seated ball valves, ball valves both small flow resistance, operating stem rotates 90 ° to achieve rapid closure, manual, automatic conversion easy, easy automation and control.

     Antistatic ideal fire safety valve:
Metal seat, extreme temperature resistance 500 ℃, with a natural fire anti-static function.

     The most economical material combinations:
     Our metal seal valve, depending on use conditions, the choice of different sealing deputy, can achieve the most economical and reasonable choice.

     Arbitrarily chosen mode of operation:
     TO our metal seal valve, the valve according to the size and purpose of use, you can choose a variety of operating mechanism.
