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
