[pneumatic V type ball valve VQ647F] high quality ball valve series products. The product's overall parts are machined by precision CNC machine tools, which effectively ensures the product's fastness and tightness, and greatly improves the sealing performance and service life. Shanghai double the high-tech development [V type pneumatic ball valve body with internal center] hemisphere V shape design of the new structure. With the remaining forcibly cut the sealing surface of the fiber in the ball. It effectively ensures the reliability of the seal. This type of valve is specially used for fibrous or contain small solid particles in suspension and solid granular control.
Pneumatic V ball valve product use:
The V ball valve is a kind of advanced control valve with a right angle slewing structure. It is matched with the valve positioner and can realize proportional adjustment. It is matched with two position five way electromagnetic and control box, and can realize switch control. It is suitable for control of gas, liquid and solid particle medium. Because of no gap between the spool and the valve seat is rotating, so have a lot of shear force and self-cleaning performance, especially for fibrous or contain small solid particles in suspension and solid granular control. Therefore, this product can be widely used in petroleum, chemical, papermaking, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial departments.
The product structure features of pneumatic V ball valve:
1. The pneumatic V ball valve is composed of V valve body and pneumatic actuator and other accessories. It is a high control valve for the right angle gyration structure.
2. It has excellent regulation characteristics: the V valve has an approximate equal percentage inherent flow characteristic and the adjustable ratio of up to 300:1. Therefore, the V type valve can provide accurate control within a wide range of changes.
3, the maximum flow volume: because of its streamline shape and full right angle rotation control, the maximum volume is extremely high, the capacity is very large, and the flow resistance is small, so smaller and more economical and practical valve size can be used.
4, V type valve adopts double bearing structure, the mechanical stability is high, the starting torque is small, and the valve has excellent sensitivity and induction speed.
5, maximum reliability (safety): the body is a whole structure, strong and durable, the operation is not affected by the pressure of the pipe, and can avoid the leakage of the valve body.
6, the superior sealing of metal valve seat: V valve adopts movable metal valve seat, which has self-help compensation function, and has excellent sealing performance and long service life. In the flow, the leakage is less than 10-6 * rated flow coefficient.
7, super cutting ability: V valve adopts metal hard seal structure, V spool and metal valve seat are in the process of rotation. V notch and valve seat produce a powerful shear to cut off impurities such as fiber, and have self cleaning function to avoid valve clamping.
8. The pneumatic V ball valve is compact, compact and light, easy to install and easy to maintain.
9. The pneumatic actuator adopts the piston cylinder and the curved arm conversion structure. The output torque is large and the volume is small. The executing agency has a high level of protection with fully sealed waterproof design. The cylinder block adopts the imported mirror cylinder, which has no oil lubrication, small friction coefficient, corrosion resistance, and super durability and reliability. All transmission bearings are lubricated with self lubricating bearings without oil to ensure that the drive shaft is not worn.
