A DIN angle bellows the globe valve is used to control the flow of fluids or gases in a pipeline. It is set up to provide a reliable and leak-free sealing solution in various industries. “DIN” stands for the German Institute for Standardization (Deutsches Institut für Normung). It sets the standards for many industrial products. The DIN angle bellows the globe valve conforms to these specific standards.
The valve installed on the pipeline must have the area for operation and maintenance. For flanged stop valves, users should select bolts according to the temperature and medium. For butt-end valve construction, cast must will weld and heat-treat to given standard requirements. Welding must be performed by skilled personnel only after process qualification. You should check the location arrow while opening and closing the valve. Overusing the “F” twist can show warping of bellows and damage to inner parts.
The working principle of the globe valve is to close the sealing surfaces with the disc. Globe valves are directional during installation and only allow a one-way media flow. The end-to-end and face-to-face dimensions of the globe valve are more than other valves. The fluid resistance is extensive, so valve sealing is not vital for long work. The throttle valve controls fluid flow by changing the choke length or cross-section.
When opening, the globe valves are designed with an inlet low and outlet high to lower the flow and save effort. Conversely, the shut between the valve casing and bonnet is not stressed when the valve is closed. It will not be affected by the temperature and pressure of the medium for a long time. It also reduces the probability of leakage. Also, the stuffing can be added or changed when the valve is closed, which is easy for maintenance.
In heat transfer, oil pipeline transfer often causes corrosion and other problems. The corrosion will affect the bellows differently, shorten life, and even damage. To prevent this damage, you can use the bellow seal valves. We have described why the bellow seal valve is used in heat transfer pipelines. If you have a question, contact us happily.
Here are some other types according to the type of body of globe valves;
● Y types
● Z types
● Angle Types
The globe valve working process from the working floor must be about 1.2m. It should be set to shut off the valve operating platform when the base of the hand wheel is more than 1.8m. Cut-off valve more pipeline help the installation of the valve for easy processing. The average distance between the hand wheel does not exceed 100mm.
You should also consider some below points:
Regular maintenance of the valve should be needed. You should pay attention to check there is no valve leaking.
If the valve is not working regularly, then cycle the valve. It will prevent the disc from bedding itself in the seat.
You can use a grease gun to grease the crossbar on the nipple. If needed, you should lubricate the spindle.
If packing needs adjustment, you should need to tighten the gland bolts slightly. The gland will be damaged if you over-tighten it. You need to replace the packing if leaking through the gland appears.
One of the most common uses for globe valves is bypass lines. Bypass lines reroute fluid around a closed system. Globe valves are installed to control fluid flow in the bypass line. This is because globe valves can easily open and close, offering high precision when controlling fluid flow. As a result, globe valves are an essential component in many types of bypass systems.
Globe valves are smooth or flat motion valves most employed to start, stop, and throttle flow. Their structure looks like a stem that moves up and down to control flow inside the valve. The system includes a disc plug and seat commonly tightened into the valve body. Seats produce in an inclined plane or parallel to the flow line. These control valves are most often used to open or close the flow valve throttle in a system. The disk of a globe valve can be drawn entirely from the flow path, or it can completely close the flow path.
