2875 series German Baode direct acting proportional BURKERT solenoid valve

2875 series German Baode direct acting proportional BURKERT solenoid valve

The direct acting electromagnetic control valve 2875 is used as a regulating unit in the control circuit. Due to the use of elastic valve seat seals, the valve has good sealing performance (with built-in shut-off function) and can achieve rated pressure equivalent to the diameter. The plunger of the valve has no friction, therefore it hasVery good regulation performance. This valve is particularly suitable for applications with high control requirements (wide control range, dry gas, etc.).

German BURKERT electromagnetic valveIt belongs to a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve disc from below, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it, so the diameter of the valve stem should be larger, otherwise the valve stem bending fault may occur. The "Three Modernizations" of valves in our country once stipulated that the flow direction of globe valves should be from top to bottom. So the fully open position of the shut-off valve should be determined by the stroke of the valve disc.

Proportional valves have the following advantages:
1. The structure is simple and easy to manufacture and maintain.
2. Small work schedule and short opening and closing time.
3. Good sealing performance, low friction between sealing surfaces, and long service life.

German BURKERT electromagnetic valveThe installation and maintenance should pay attention to the following matters:

1. The handwheel and handle operated shut-off valve can be installed at any position in the pipeline.
2. Handwheels, handles, and transmission mechanisms are not allowed for lifting purposes.
3. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
Baode BURKERT pneumatic globe valve adopts a double acting cylinder, which uses upper chamber intake or lower chamber intake to remotely control the valve, making operation convenient and flexible. Cylinder media: compressed air, nitrogen. Simple structure, easy to manufacture and maintain; Small work schedule and short opening and closing time; The sealing surface between the closing body (valve disc) and the valve seat adopts conical sealing, which has low closing force, erosion resistance, and reliable sealing. The valve seat can be a replaceable valve seat, which can be freely combined with the sealing surface material of the closing element to meet the working conditions and extend the service life.
The standard supplied brass valve body meets the requirements of all European drinking water standards. Featuring anti zinc corrosion brass type, suitable for other applications. The valve body material also includes stainless steel. The electromagnetic coil is encapsulated with chemically resistant epoxy resin. All coils can be equipped with power reducing electronic circuits for energy conservation. Can be equipped with a manual switch for easy debugging and testing.

German BURKERT electromagnetic valveStructural features:
1. Carefully selected materials, in compliance with relevant domestic and international standards, with a reasonable structure and beautiful appearance.
2. The sealing surface of the valve disc and seat is made of iron-based alloy or Stellite cobalt based hard alloy, which is wear-resistant, high-temperature resistant, corrosion-resistant, has good abrasion resistance, and has a long service life.
3. The valve stem has undergone quenching and surface nitriding treatment, providing excellent corrosion resistance and abrasion resistance.
4. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
5. The valve body material variety is complete, and the packing and gasket can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
6. The reverse seal is made by connecting the sealing seat with threads or welding austenitic stainless steel on the body, ensuring reliable sealing. The replacement of the packing can be carried out without stopping the machine, which is convenient and fast, and does not affect the operation of the system.
