Features:  

1.  Blow-out Proof Stem. The lower end of the stem is T-shaped structured, protected by the boss of the body, which assures stem retention at any pressure and acts as a backseat.
2. Anti-static Device. A spring-loaded plunger fitted on the stem keeps constant contact between the ball, stem, and body to create an electric path to transfer charges, avoiding acceleration of static electricity as a result of friction during valve on-off. The such build-up is utterly hazardous to some services.
3. Position Indicator. Double D stems head design provides mounting of the lever always in parallel to the flow passage. Misalignment of the lever is thus prevented.
4. Locking Device. A facility for mounting a locking device for the prevention of accidental valve operation is provided.

Benefits:

1. Low Emission Control. Modern industry sectors are challenged by valve fugitive emissions to control service fluids released from the valve and curb environmental degradation. Therefore, emission control features the JIANENG floating ball valves Series. Low emission packing is assembled, whose max. leaking rate of design and test stands at 100 PPM
2. Roughness control over stem and packing. Stem surface roughness is strictly restricted between Ra0.4 and Ra0.8, which ensures the entry of graphite packing powder into tiny stem scratches to function as a lubricator, minimizing leakages around the stem. Max. The roughness of the stuffing box is Ra3.2, which is a proper value to hold the packing ring in place and result in better sealing performance.
3. Low Emission Packing. The packing is a combination of the parallel and vertical layers which is made of die-formed graphite ring processed by flexible graphite, characterizing heat resistance, less stress relaxation, and low creep. The special structure means low friction on the rotary stem, providing stabilized seal capability for the valve for a long time under frequent functioning. For low-temperature and cryogenic service, the standard V shape PTFE packing rings are installed for low emission control.
