Which is a good supplier of BURKERT globe valves

German Baode solenoid valve BURKERT globe valve
Burkert, GermanySpecialized fluid control system products have been widely used in various industries, especially in water/wastewater treatment, beer and beverage, food processing, pharmaceuticals and medical equipment, disinfection and cleaning, and textile and chemical industries, which have great advantages and broad market prospects. And in some harsh working conditions, such as satellites, space laboratories, nuclear reactors, and deep-sea exploration devices, the "Burkert" product has also demonstrated its accuracy and reliability
BURKERT specializes in process products such as solenoid valves, butterfly valves, ball valves, angle valves, check valves, filters, pneumatic drives, sensors, and controllers. Burkert has been committed to the research and manufacturing of products and systems in the field of fluid control. Nowadays, Burkert has developed into a company with over 3000 employees and five production plants in Germany and France. A multinational corporation with subsidiaries established in over forty countries and regions, becoming a leader in the field of fluid control systems. Direct acting medium isolation solenoid valve, with the largest diameter DN 8

German Baode solenoid valve BURKERT globe valve
Baode BURKERT pneumatic globe valve belongs to the forced sealing type 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. In recent years, with the emergence of self sealing valves, the flow of medium in shut-off valves has shifted from above the valve disc into the valve chamber. Under the pressure of the medium, the force required to close the valve is small, while the force required to open the valve is large, resulting in a corresponding reduction in the diameter of the valve stem. Meanwhile, under the influence of the medium, this type of valve is also relatively tight. The "Three Modernizations" of valves in our country once stipulated that the flow direction of globe valves should be from top to bottom.

When the shut-off valve is opened and the opening height of the valve disc is 25% to 30% of the nominal diameter, the flow rate has reached, indicating that the valve has reached the fully open position. So the fully open position of the shut-off valve should be determined by the stroke of the valve disc. Globe 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.

The disadvantages of globe valves are as follows:
1. The fluid resistance is high, requiring a large amount of force to open and close.
2. Not suitable for media with particles, high viscosity, and easy coking.
3. Poor regulation performance.

The types of globe valves are divided into external thread type and internal thread type according to the position of the valve stem thread. According to the flow direction of the medium, there are straight through, direct current, and angular types. Globe valves are divided into packing sealed globe valves and bellows sealed globe valves according to their sealing forms.

The installation and maintenance of globe valves 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 in the direction indicated by the arrow * on the valve body.

Baode BURKERT Pneumatic Stop ValveAdopting a double acting cylinder, the valve can be remotely controlled using upper or lower chamber intake, making it easy and flexible to operate. 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 combined with the sealing surface material of the closing element to meet the working conditions and extend the service life
