Pneumatic V type ball valve

A, use pneumatic V type ball valve is a quarter-turn structure of advanced control valve, and supporting the use of valve positioner can realize proportional control; And two five electromagnetic valve and control box supporting the use, may realize the switch control. V type ball valve valve core is designed with special shape of V notch, with accurate intercepting property and control function, applicable to all kinds of control occasions, compact structure, small size, can be tight lie installation etc. Suitable for gas, liquid and solid granular media control. Due to the valve core and valve seat is no gap between turning, so have a lot of shear force and sanctified performance, especially applicable to contain fibrous or small solid particle suspension and solid granular control. This product can be widely used in oil, chemical industry, paper making, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial departments of the automatic control system.
Second, the characteristics of 1, pneumatic V type ball valve by V body and pneumatic actuators and other accessories composition. Is a quarter-turn structure of advanced control valve. V type ball valve long-term do not need to repair and long service life, to provide you with the true high efficiency to control the process condition of a kind of valve. 2, have good control characteristics: V type valve has a nearly the same percentage of natural flow characteristics and as high as 300:1 adjustable ratio. So V type valve can be in wide width range to provide accurate control. 3, maximum flow volume: because of its streamlined appearance and full quarter-turn control, because the maximum volume is extremely high, pass the ability is specially big, small flow resistance, so can use smaller more economic and practical valve size. 4, V type valve adopts double bearing structure, mechanical stability, high starting torque is small, ensure the valve has good sensitivity and induction rate. 5, maximum reliable (safety) sex: body is a whole structure, durable, the operation is not affected by line pressure influence, and can avoid the leakage of the valve body. 6, metal seat is superior sealing: V type valve using metal valve seat, has the help compensation function, and has the superior seal performance and long service life. In the flow, leakage and rated flow coefficient. 7, super shear capacity: V type valve mining have metal hard seal structure, V type valve core and metal seat in turning process, V notch and seat produce a powerful shear force can cut off the fiber material, and has since clean function, avoid valve jammed phenomenon. Eight, pneumatic V type ball valve structure is compact, small, light and easy installation, convenient maintenance. 9, pneumatic actuators using piston cylinder and crank arm conversion structure, output torque, small volume essence. Actuator adopts full seal waterproof design protection level high. Cylinder block USES the import mirror cylinder, without oil lubrication, coefficient of friction small, corrosion resistance, with super durability and reliability. All drive bearing adopts boundary self lubricating bearing no oil lubrication, ensure that drive shaft not wearing.

Actuator using new series AT type pneumatic actuators, double acting and single acting (spring reset), rack and pinion, safe and reliable; The large diameter valve series AW type pneumatic actuator fork transmission, reasonable structure, large output torque, double acting and single acting. 1, gear type double piston, the output torque, small volume. 2, cylinder choose aluminum alloy material, light weight, beautiful appearance. 3, can be in the top, bottom, installation manual operating mechanism. 4, rack connection can adjust the opening Angle, the rated flow. 5, actuator optional charged signal feedback directives and all kinds of accessories to realize automation. 6, IS05211 standard connection for the installation of the product change provides convenient. 7, both ends adjustable pitch screw can make the standard product at 0 ° and 90 ° ± 5 ° have adjustable range. To ensure that the valve and the precision of the synchronization.
