Product Description

Automatic Valve Manufacturer, Pneumatic Ball Valve, Pneumatic Flanged Ball Valve

Uses and Structural  Features of Product

Pneumatic  ball  valve  series  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 the automatic or adjustment control of fluid, together with automatic pneumatic meters.

The Structureal Features of Pneumatic Ball Valves Series:

Pneumatic Actuator uses  new-style AT pneumatic actuator,  provided with both double-acting and single-acting types (spring reposition),  driven  by  gear and  rack  with  high  dependability;  big  diamete valves are  diven by  AW  pneumatic  actuator  on  pull extraction  manner,  with reasonable stucture  and  large  output  torque  as  well  as  double-acting  and  single-acting  types  (spring reposition). Refer to our stylebook of pneumatic actuator for more details information.

•Shell Sturcture: As per useres' requirements and real working conditions, fixed ball valves can be designed to three structures including cast, forged and full-welded, and valves of full-welded structure are mainly applicable for buried use.

Unique  ISealing Sturcture of  Valve Base Floating ball  valve adopts the sturcture of  lip-type elastic  sealing ring to insure the sealing  dependability.  For  ball  valves  used  in  low-tension,  ultra-low-tension  or  vacuum  conditions,  the  valve-base  sealing structure with leaf spring loading is adopted to maintain long-time reliable sesling. The valve-base of high-or medium-temperature ball valve may usepara-position polyphenylene of metal material.

According to the difference in pressure, medium character and sealing requirements, fixed ball valve may choose structures of front-ball sealing, back-ball sealing or front-back double sealing. The valve base of high-oor medium-temperature ball valve may use pare-position polyphenylene or metal material.

eObsturction and Drainage: When valve is io off-position, the valve bases at upper and lower  stream will interdict the fluid, and the deposit in the cavty may be discharged by drainage device.

•Automatic Pressure-relieving Sturcture:  In case of abnormal rise of pressure occurred in cloaca cavity, the mediums in it may drive the valve base with its self-thrust to realize automatic pressure relief. thus to ensure the safety of valve body.

• Reliable  Sealing  of  Stem:  Valve  stem  adopts  the  downward  installation  sturcture  with  back  sesling.  The  sealing  power increases along with the rise of medium pressure, thus to ensure reliable sealing of valve stem. In addition, stem will not burst forth in case of abnormal pressure rise.

•Fireproof Sturcture: Fireproof sturcture may be adopted for ball valve as per working conditions and users' requirements. The firep oof design confoms to API  60  and JB/T6899 standards  etc.  In  case of soft  sealing ring being damaged in fire,  the  Iieproof

structure can stop the large leakage of medium, thus to avoid further expansion of fire.

• Anti-static  Strusture:  When operating,  the friction  between  sphere  and  base may  cause static  charge  accumulated on  the sphere. To avoid static spark, static device is provided on the valve to educt the electric charge on the sphere.

• Full Bore Structure and  Reduced Bore Structure:  These two  serices are offered to meet users’ different requirements. The passage inside diameter of full bore ball valve is the same as that of pipe, making it convenient for control and cleaning. The weight of reduced bore ball valve is  relativey smaller,  but  the fluid resistance is only arund  1/7 of  that of  stop valve with  the same caliber. Therefore, the application prospect is much better for the latter.
