Pneumatic control valve structure characteristics


Structural features of pneumatic control valve:

1. Pneumatic control valve does not need to be repaired for a long time and has a long service life. It provides you with a valve that can control the process conditions with real high efficiency.

2. Pneumatic control valve has excellent adjustment characteristics: V-shaped ball valve has approximately equal percentage flow characteristics and an adjustable ratio of up to 300:1. Therefore, the V-shaped butterfly valve can provide accurate control within a wide range of changes.

3. The maximum movable volume of the pneumatic control valve: because of its streamlined layover and full right-angle reversal control, the maximum volume is particularly high, flow capacity is particularly large, and flow resistance is small, so it can be used smaller and more economical.

4. The pneumatic control valve adopts double-bearing structure, which has high mechanical stability and small starting torque, which ensures that the valve has good sensitivity and sensing speed. Maximum reliability (safety): The valve body is an integral gate valve structure, sturdy and durable, and operation It is not affected by pipeline pressure and can prevent leakage of the valve body.

5. Excellent sealing performance of metal valve seat: V-type valve uses movable metal seat, which has self-compensation function, and has excellent sealing performance and long service life.

6. Super shearing ability: The V-shaped ball valve uses a metal hard seal structure. Among the structural characteristics of the V-shaped valve disc and metal valve seat in the reversal process of the electric-stroke pneumatic control valve, the V-shaped gap and the valve seat The strong shearing force can block impurities such as fibers, and has a self-cleaning function to prevent the valve from jamming the shut-off valve.

7. The pneumatic control valve has compact structure, fine and light weight, convenient installation and simple protection.

8. Pneumatic actuator adopts piston type cylinder and crank arm conversion structure, with large output torque and small size. The actuator adopts fully sealed waterproof and high protection level. The cylinder adopts imported mirror cylinder, which is oil-free and smooth, with low friction coefficient and corrosion resistance. , With super durability and reliability. All transmission bearings are selected from the gap self-lubricating bearing oil-free smooth, to ensure that the transmission shaft is not worn.

9. pneumatic regulating ball valve has the action of rotating 90 degrees, the cock body is a sphere, with a circular through hole or channel passing through its axis. The ball valve is mainly used to block, distribute and change the direction of movement of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque can be closed tightly. ball valve is most suitable for switching and blocking valves, but recent developments have planned the ball valve to save and control flow.
