1.Reliable sealing: PTFE single material ring embedded in a stainless steel seat, the end of the metal seat with springs to ensure adequate preload ring, valve sealing surface wear in the use of the process in the spring under the valvecontinue to ensure good sealing performance.

2, effortless operation: the sphere is supported by the upper and lower bearings to reduce friction eliminate import pressure pushes the ball and seal seat and a huge seal load caused by excessive torque.

3, structural fire protection: To prevent due to the emergence of flammable or fire, PTFE seals burned, the occurrence of a large leak, and contribute to the fire, the ball and seat set fire sealing ring seals burnedin the spring force, the valve seat sealing ring quickly to the sphere, the formation of metal-to-metal seal, play a certain degree of sealing effect, the fire resistance the trials met API6FA and API607 standard requirements.

4 the sealed emergency grease ambulance: foreign body in the media or fire caused by seat sealing accidental failure, the grease valve provides a quick connection with the grease gun, quickly and easily sealant injected into the valve seat sealing parts, ease leak.

5, automatic pressure relief function: When the medium pressure valve in the cavity stagnation abnormal elevation of more than spring preload, seat back out of the sphere, to achieve the effect of automatic pressure relief, after discharging the pressure automatic recovery.

6, the discharge line: valve body from top to bottom are set excretory pore seat inspection for leaks, at work, the valve is fully open or fully closed, relieved the pressure in the chamber can be directly replace the packing in the cavity; emissions left in it to reduce the medium pollution to the valve, fixed ball valve is widely used in food, medicine, petroleum, chemical, natural gas, iron and steel, paper and other media transfer line cut or circulation. You can also give this device injection cleaning agent or lubricant on the sealing surface for cleaning.
