Characters:
Pneumatic ball valves are widely used in natural gas, oil chemical industry, metallurgy, papermaking, power, mining, printing and dying, biological pharmacy, daily chemicals, foodstuff and beverage, water treatment and air treatment etc. For automatic control and adjustment control of fluid, together with automatic pneumatic meters.
Series pneumatic ball valve structure is characterized by:
I.Pneumatic Actuators: The New pneumatic actuators, double acting and single- acting(spring return), rack and pinion, safe and reliable; large diameter valves using pneumatic actuator series fork-type transmission, structure reasonable, the output torque, a double -acting and single -acting(spring return).
II.Shell structure:fixed ball valve actual working conditions of different designs for casting structure, the structure and the three forms of forging all -welded construction, fully welded ball valve structure which is mainly applied to buried according to user needs and use.
III.The unique seating structure: Floating ball using elastic lip seal design to ensure reliability of sealing for low pressure, Ultra-low pressure or vacuum: positive status with ball, uses a leaf spring-loaded seat seal structure ensures a reliable seal long ball,. Medium, hign temperature valve seat material could be RPTFE or metal materials.
IV:Obstruction and excretion: When the valve is closed, on the downstream side of the seat so that the liquid blocking, Indigestion matter body cavity can be excreted thrust and automatic pressure relief valve to ensure the safety valve.
V:Reliable stem seal: Stem seal downloading using inverted structure, inverted seal sealing force with increasing media pressure increases, it can ensure reliable sealing of valve stem, and when the stem abnormalities boost stem not ejected.
VI:Fireproof structure: according to the conditions and needs of users, ball valves can be designed for structural fire protection. API**7 fire ball design, implemetation and JB/T***9 and other standards, leaving the soft seal the event of fire burning, the fire ball structure can prevent a lot of media leaks and prevent further expansion of the fire.
VII:Anti-static structure: When the operation of the valve, due to friction between the ball and seat, will produce cattle and accumulation of electrostatic charge on the sphere, in order to prevent the generation of static elctricaity spark, and electrostatic device on the valve, will accumulate in the sphere of charge exported.
VIII:Full bore structure and necking structure: To meet the different needs of users, the company has a full bore ball valve products and necking two series. Full bore ball valve inside diameter of the pipe is consistent channel diameter, easy to manage cleaning, and weight reduced bore ball valves are relatively mild, but the fluid resistances is only about 1/7 of the same caliber cut-off valve, so reduced bore ball valves prospects relatively broad.
