Pneumatic V-type regulating ball valve: It is a rotary ball valve whose core valve seat is made of metal or metal-to-PTFE seal. Its advantage is that it combines the control characteristics of the ball valve and the butterfly valve into one, and can be used as a regulating valve. It can also be used as a shut-off valve. Because of the shearing function, it is more suitable for working conditions with particles in the medium. Pneumatic V-shaped ball valve is a control valve with a right-angle rotation structure, which can be divided into pneumatic V-shaped regulating ball valve and pneumatic V-shaped cut-off ball valve. It can be used in conjunction with a valve positioner to achieve proportional adjustment. It can be used with two-position five-way solenoid valve and control box to realize on-off control. The valve core of the dynamic V-shaped ball valve is designed with a special-shaped V-shaped gap, which has accurate interception properties and control functions. The pneumatic V-shaped ball valve is suitable for a variety of control occasions. It has the advantages of compact structure, small volume, and can be installed tightly. Pneumatic actuators include double-acting and single-acting (spring return), rack and pinion transmission; large-diameter valves adopt series AW-type pneumatic actuators with fork-pull transmission, reasonable structure, large output torque, double-acting and single-acting Action style.
The main features of the pneumatic V-type regulating ball valve are:
(1) Pneumatic V-type ball valve is composed of valve body, pneumatic actuator and other accessories. It is a control valve with a right-angle rotation structure. The V-shaped ball valve does not need to be repaired for a long time and has a long service life.
(2) Stable adjustment characteristics: Pneumatic V-type ball valve has an inherent flow characteristic of approximately equal percentage and an adjustable ratio of up to 300:1. Therefore, the pneumatic V-ball valve can provide accurate control in a wide range of changes.
(3) Upper limit flow volume: Due to its streamlined shape and full right-angle rotation control, the upper limit of the volume is higher, the flow capacity is large, and the flow resistance is small, so a smaller economic valve size can be used.
(4) The pneumatic V-shaped ball valve adopts a double-bearing structure, with high mechanical stability and low starting torque, so that the valve has better sensitivity and sensing speed.
(5) Stability: The valve body is an integral structure, the operation is not affected by pipeline pressure, and the leakage of the valve body can be prevented.
(6) The tightness of the metal valve seat: The pneumatic V-shaped ball valve adopts a movable metal valve seat, which has the function of assisting compensation, and has superior sealing performance and long service life. In the flow direction, the leakage is 10 rated flow coefficient.
(7) Strong shearing ability: The pneumatic V-shaped ball valve adopts a metal hard seal structure. During the rotation of the pneumatic V-shaped ball valve core and metal valve seat, the V-shaped gap and the valve seat produce a strong shearing force. It cuts off impurities such as fibers and has a self-cleaning function to prevent valve jamming.
(8) The pneumatic V-shaped ball valve has compact structure, small and light weight, convenient installation and easy maintenance.
(9) Pneumatic actuator adopts piston type cylinder and crank arm conversion structure, with large output torque and small volume. The actuator adopts a fully sealed and waterproof design with high protection level. The cylinder block adopts a compact mirror cylinder, no oil lubrication, low friction coefficient, corrosion resistance, strong durability and stability. The transmission bearings are all self-lubricating bearings without oil lubrication, so that the transmission shaft will not be damaged.
