Overview for Angle Seat Piston Valve ASV200

1. With the display opening or closing position of valve.
2. External pneumatic pilot, can increase the service life, 5 million times without leakage, maintenance-free.
3. There is a self-adjusting sealing gland between the overflow port and the slider, can improve the sealing performance.
4. ASV200 Angle Seat Valve body is angle seat structure, can achieve large flow (especially compared with ordinary stop valve), compact structure and fast response.
5. Angle Seat Valve Sealing material: Use long life German packer seals.
6. Angle Seat Valve body material: Stainless steel.
7. Control gas source: Air.
8. Control medium: High temperature steam.

Advantage for Angle Seat Piston Valve

1. The pneumatic device is simple in structure, light in weight and simple in installation and maintenance. The medium is air, which is not easy to burn compared with the hydraulic medium, so it is safe to use.
2. The working medium is air. The exhaust treatment is simple, does not pollute the environment, and has low cost.
3. The adjustment of output force and working speed is very easy. The operating speed of the cylinder is generally less than 1M/S, which is faster than the hydraulic and electrical modes.
4. High reliability and long service life. The number of effective actions of electrical components is about millions of times, while the life of general solenoid valves is more than 30 million times, and some good quality valves exceed 200 million times.
5. Using the compressibility of air, energy can be stored to achieve centralized gas supply. Energy can be released in a short time to achieve high speed response in intermittent motion. Buffer can be achieved. It has strong adaptability to impact load and overload. Under certain conditions, the pneumatic device can be self-retaining.
6. Full pneumatic control has the ability of fireproof, explosion-proof and moisture-proof. Compared with hydraulic mode, pneumatic mode can be used at high temperature.
7. Compressed air can be supplied centrally, long distance transportation.

Disadvantage for Angle Seat Piston Valve

1. Because of the compressibility of the air, the speed of the cylinder is easily changed by the load. This problem can be overcome by using gas-liquid linkage type.
2. When the Pneumatic Solenoid Valve is moving at low speed, the frictional force accounts for a large proportion of the thrust, and the low-speed stability of the cylinder is not as good as that of the hydraulic cylinder.
3. Although in many applications, the output force of the cylinder can meet the working requirements, its output force is smaller than that of the hydraulic cylinder.
Pneumatic technology is a specialized technology that uses compressed air as a medium to drive and control machinery. Because it has the advantages of energy saving, pollution-free, high efficiency, low cost, safety and reliability, and simple structure, it is widely used in various machinery and production lines. In the past, pneumatic systems and components on production lines such as automobiles and tractors were designed, manufactured and repaired by each factory.

Troubleshooting for Angle Seat Piston Valve

The Angle Seat Piston Valve will also malfunction due to improper installation and use.
Fault Cause analysis Troubleshooting
External leakage Piston rod end leak Piston rod installation is eccentric
Insufficient supply of lubricant
Piston seal is worn
Piston rod bearing mating surface has impurities
Piston rod has scratch
Re-install the adjust the piston rod free from eccentric lateral loads.
Check if the lubricator works normally
Replace the seal.
Clean and remove impurities, install the replace dust cover.
Replace the piston rod.
  Air leak between the cylinder and the cylinder head    
  Air leakage at the buffer adjustment    
Internal leakage Piston gas at both ends of the piston Piston seal is damaged
Poor lubrication
The piston is stuck and the piston surface is defective.
Impurities squeeze into the sealing surface
Replace seal
Check if the lubricator works normally
Re-install the adjust the piston rod free from eccentric lateral loads.
Remove impurities and purify compressed air.
Insufficient output
Unstable action
Poor lubrication
Piston or piston rod is jammed
Insufficient air supply flow
Have condensed water impurities
Check if the lubricator works normally
Reinstall the adjustment to eliminate eccentric lateral loads.
Increase the connection or pipe size
Pay attention to purify and dry the compressed air to prevent condensation.
Poor buffering effect Cushion seal is worn
Adjusting screw is damaged
Cylinder speed is too fast
Replace the seal
Replace the adjusting screw
Notice whether the buffer mechanism is suitable
Damage Piston rod damage Have eccentric lateral load
Piston rod subjected to impact load
The speed of the cylinder is too fast
Eliminate eccentric lateral load
Impact cannot be added to the piston rod
Setting up buffer device
  Cylinder cover damage Buffer mechanism does not work Buffer mechanism is set in the external or loop
