Pneumatic piston cam deflection adjustment cut-off valve HB2810

Pneumatic piston cam deflection cut-off valve is an advanced control valve with a right angle rotary structure. It is used in conjunction with a valve positioner to achieve proportional adjustment; Used in conjunction with a two position five way solenoid valve and control box, it can achieve switch control. The V-shaped pneumatic ball valve core is designed with a specially shaped V-shaped notch, which has precise flow characteristics and control functions, suitable for various control occasions, compact structure, small volume, and can be installed in a tight position. Suitable for controlling gas, liquid, and solid granular media. Due to the seamless rotation between the valve core and valve seat, it has great shear force and self-cleaning performance, especially suitable for controlling suspensions and solid particles containing fibers or small solid particles. Therefore, this product can be widely used in the self-control systems of industrial sectors such as petroleum, chemical, papermaking, chemical fiber, power, metallurgy, pharmaceuticals, and environmental protection.

2、 Characteristics

1. The pneumatic piston cam deflection cut-off valve consists of a V-shaped valve body, a pneumatic actuator, and other accessories. It is an advanced control valve with a right angle rotary structure. The V-shaped ball valve does not require repair for a long time and has a long service life, providing you with a truly efficient valve for controlling process conditions.

2. Excellent regulating characteristics: The V-shaped valve has an approximately equal percentage inherent flow characteristic and an adjustable ratio of up to 300:1. Therefore, V-shaped valves can provide precise control over a wide range of variations.

3. Flow volume: Due to its streamlined shape and full right angle rotation control, the volume value is particularly high, the flow capacity is particularly large, and the flow resistance is small, so smaller and more economical valve sizes can be used.

4. The V-shaped valve adopts a dual bearing structure, which has high mechanical stability and low starting torque, ensuring the sensitivity and sensing speed of the valve.

5. Reliability (safety): The valve body is an integral structure, sturdy and durable, and the operation is not affected by pipeline pressure, which can avoid the valve body

Sealing performance of metal valve seat: The V-shaped valve adopts a movable metal valve seat, which has the function of assisting compensation, and has * sealing performance and ultra long service life. In terms of flow direction, the leakage rate is 10% of the rated flow coefficient.

7. Shear ability: The V-shaped valve adopts a metal hard seal structure. During the rotation process, the V-shaped valve core and metal valve seat generate a strong shear force between the V-shaped notch and the valve seat, which can cut off fibers and other impurities, and has self-cleaning function to avoid valve jamming.

8. The pneumatic V-shaped ball valve has a compact structure, is small and lightweight, easy to install, and easy to maintain.

9. The pneumatic actuator adopts a piston type cylinder and a curved arm conversion structure, with a large output torque and small volume precision. The actuator adopts a fully sealed waterproof design with high protection level. The cylinder block adopts imported mirror cylinder, oil-free lubrication, low friction coefficient, corrosion resistance, good durability and reliability. All transmission bearings adopt boundary self-lubricating bearings without oil lubrication to ensure that the transmission shaft is not worn.

actuator

Adopting a new series of AT or GT pneumatic actuators, with double acting and single acting (spring reset), gear rack transmission, safe and reliable; The large-diameter valve adopts a series of AW type pneumatic actuator fork type transmission, with a reasonable structure and large output torque, and is available in double acting and single acting types.

1. Gear type dual piston, with large output torque and small volume.

2. The cylinder is made of aluminum material, which is lightweight and aesthetically pleasing.

3. Manual operating mechanisms can be installed at the top and bottom.

4. The rack and pinion connection can adjust the opening angle and rated flow rate.

5. The actuator can be equipped with live signal feedback indicators and various accessories to achieve automated operation.
