Application, characteristics, and working principle of FESTO solenoid valve in Germany

The German FESTO solenoid valve is a valve driven by compressed air. The practice of only specifying specifications, categories, and working pressures when purchasing pneumatic valves to meet procurement requirements can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.

There are many common types of valves, and pneumatic valves are one of them. The performance of pneumatic valves is excellent, and they are widely used in the industrial industry with great value. At present, there are many types of pneumatic valves on the market, and different specifications of valves may have differences in appearance and performance, which can meet the needs of different industries.

The FESTO solenoid valve from Germany is a right angle rotary structure that can be used in conjunction with a valve positioner to achieve proportional adjustment; The V-shaped valve core is suitable for various regulating occasions, with a large rated flow coefficient, adjustable ratio, sealing effect, zero sensitivity regulating performance, small volume, and can be installed vertically and horizontally. Suitable for controlling media such as gases, vapors, liquids, etc.

Application, characteristics, and working principle of FESTO solenoid valve in Germany

A、 Purpose: It is a right angle rotating structure that can be used in conjunction with valve positioners to achieve proportional adjustment; The V-shaped valve core has a large rated flow coefficient, adjustable ratio, sealing effect, zero sensitivity to adjustment performance, small volume, and can be installed vertically and horizontally in various regulating occasions. Suitable for controlling media such as gases, vapors, liquids, etc.

B、 Features: It is a right angle rotating structure composed of a V-shaped valve body, pneumatic actuator, locator, and other accessories; There is an inherent flow characteristic that is approximately equal in percentage; Adopting a dual bearing structure, the starting torque is small, and it has sensitivity and sensing speed; The cutting ability.

C、 The pneumatic piston actuator uses compressed air as the power source, which drives the crank arm to rotate 90 degrees through the movement of the piston, achieving automatic opening and closing of the valve. Its components include: adjusting bolts, actuator housing, crank arm, cylinder block, cylinder shaft, piston, connecting rod, and universal joint.

D、 The working principle of FESTO solenoid valve in Germany: Pneumatic control valve consists of an actuator and a regulating mechanism. The actuator is the thrust component of the regulating valve, which generates corresponding thrust according to the magnitude of the control signal pressure, and drives the action of the regulating mechanism. The valve body is the regulating component of a pneumatic control valve, which directly contacts the regulating medium and regulates the flow rate of the fluid.

It is a type of valve that belongs to the same category, with the difference being that its closing element is a sphere that rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. Two piece ball valve and three piece ball valve are a new type of valve widely used in recent years. So what special precautions should be taken when using and repairing eccentric hemispherical valves? Let me introduce Tianjin Yibiao Valve in detail below!

Precautions for maintenance methods of FESTO solenoid valves in Germany:

1. When the eccentric hemispherical valve is closed, there is still pressurized fluid inside the valve body.

2. Before maintenance, release the pipeline pressure and keep the valve in the open position.

3. New parts also need to be cleaned thoroughly before assembly.

4. Before maintenance, detach the actuator from the bracket.

5. Non metallic parts should be immediately removed from the cleaning agent after cleaning and should not be soaked for a long time.

6. After cleaning, it is necessary to wait for the wall cleaning agent to evaporate (which can be wiped with a silk cloth that has not been soaked in cleaning agent) before assembly, but it should not be left for a long time, otherwise it will rust and be contaminated by dust.

7. It is necessary to confirm that the pressure in the upstream and downstream pipelines of the ball valve has been relieved before proceeding with disassembly and assembly operations.

8. When disassembling and reassembling, care must be taken to prevent damage to the sealing surface of the parts, especially non-metallic parts. Special tools should be used when removing the O-ring.

9. Lubricate with grease. Lubricating grease should be compatible with the metal material, rubber parts, plastic parts, and working medium of the eccentric hemispherical valve. When the working medium is gas, special 221 lubricating grease can be used, for example. Apply a thin layer of grease on the surface of the seal installation groove, a thin layer of grease on the rubber seal, and a thin layer of grease on the sealing and friction surfaces of the valve stem.

10. Before maintenance, disconnect the power or gas source.

11. The bolts on the flange must be tightened symmetrically, gradually, and evenly during assembly.

12. The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts, and working media (such as gas) in the ball valve. When the working medium is gas, gasoline (GB484-89) can be used to clean metal parts. Non metallic parts should be cleaned with purified water or alcohol.

13. The decomposed individual parts can be cleaned by immersion washing. Metal parts that have not yet decomposed can be cleaned with a clean and fine silk cloth soaked in cleaning agent (to prevent fibers from falling off and adhering to the parts). During cleaning, all grease, dirt, adhesive buildup, dust, and other substances adhering to the wall surface must be removed.

The characteristics of the German FESTO solenoid valve are as follows:

1. Direct flow channel, with minimal pressure loss and energy efficiency.

2. The hardness of the sealing surface can cut through soft or hard debris such as steel bars and fabrics, and has a long service life.

3. The metal sealing performance is reliable, and the eccentric structure is reasonable.

4. Rotate 90 °, quickly open and close, low torque, easy to operate.
