Pneumatic Piston Control Ball Valve |
ZSHV Pneumatic V Piston Control Ball Valve （abbreviated as Control Ball Valve） is a rotary control ball valve equipped with combination of solenoid and electric positioner or pneumatic positioner. There is a V cutting on the core, which rotates relatively with the seat produces shearing stress to prevent from jamming by foreign matter. It is especially applicable to control slurry and mediums with fibre or little suspended solid. So it is widely used in petrol, chemical, medicine, metallurgy, textile, paper mill and water treatment etc. industries for controlling the flow of air, steam and liquid to meet the requirement of automatic control in production.
The series products are available in nominal pressure: PN1.6, 4.0, 6.4MPa, nominal diameter: DN25～300 and leakage level Ⅳand levelⅥ.
