Pneumatic ball valve is widely used in natural gas, oil, chemical, metallurgy, paper, power, mining, printing and dyeing, pharmaceutical, household chemicals, food and beverage, water treatment and air treatment industries to control or regulate fluid control, and supporting the use of pneumatic automation.
Pneumatic valve structure is characterized by:
◆ Pneumatic Actuator: A new series of GT-type pneumatic actuator, double-acting and single acting (spring return), rack and pinion drive, safe and reliable; large diameter valves with pneumatic actuator Series HAW-type fork-type transmission reasonable structure, the output torque, there are double acting and single acting (spring return); reference samples of our pneumatic actuators.
◆ Shell Structure: Fixed ball valve body according to user needs and the actual working conditions of the different structures can be designed for casting, forging, welding structure and all three forms, of which the main valve full welded structure for buried use.
◆ unique seating structure:
Floating ball valve with elastic lip seal design to ensure the reliability of sealing, the low-voltage, and ultra low-pressure or vacuum; working conditions with the ball, with spring loaded gate valve seat seal structure to ensure long-term reliable ball valve seal. , The high temperature ball valve seat material could be on the bit of polystyrene or metal materials.
Fixed pressure valve according to the size, media properties and sealing requirements of the different options before the ball sealing structure, the ball is on or after the seal structure of double seal structure. , The high temperature ball valve seat material could be on the bit of polystyrene or metal materials.
◆ obstruction and discharge: When the valve is turned off, on the downstream side of the seat so that the liquid blocked, the body cavity of the accumulated matters in the discharge device can be excreted.
◆ automatic pressure relief structure: among the abnormal increase of the phenomenon of cavity pressure, the medium in the cavity can depend on their thrust to promote the automatic pressure relief valve seat and to ensure the safety valves provided.
◆ reliable stem seal: valve stem seal downloading inverted structure, inverted sealed with sealing force increases with increasing media pressure, it can ensure a reliable stem sealing, and, when an abnormal pressure when the valve stem not emit.
◆ Fire Structure: According to the conditions and needs of users, the ball valve can be designed for structural fire protection. API607 fire ball valve design and implementation of the provisions of other standards JB/T6899, once leaving the soft ring of fire burning, the valve structure can prevent the fire a large number of media leaks, to prevent further expansion of the fire.
◆ Anti-static structure: When the operation of the valve, due to friction between the ball and seat, will have cattle and the accumulation of electrostatic charge on the sphere, in order to prevent static sparks, especially in the valve set on static devices, will accumulate in export charge on the sphere.
The whole structure and the reduced diameter Path Structure: In order to meet the different needs of users, the company has full bore ball valve products and the reduced diameter of two series. Ball Valve Full Bore diameter and pipe diameter the same channel for easy cleaning, and reduced diameter series ball relatively light weight, but the flow resistance of the same caliber valve is only 1 / 7 or so, it is the application of reduced diameter series ball prospects are more promising.
