Stainless steel gate valves and globe valves are the most used valves in the industry, and that’s the reason one, who are associated with industries, factories, and organizations where these two valves are used, should know about both valves. Check out valuable and must-known information about stainless steel gate valves and globe valve.
Stainless Steel Gate Valves and the Regulation of the Liquid Flow
Being the flowing matter state, liquids are harder to control when it comes to maintaining their pressures, fluidity, and flow. The liquid properties include viscosity, pressure, stress, strain, and gravity factor along with the internal motion of the particles, which make the substance hard to control.
To regulate the liquid flow, the stainless steel gate valve suppliers offer proficient gate valves to the system that includes stainless steel liquid flow paths so that the opening of liquid flow can be shut off or opened, respectively. The structure of the gate valves is extremely compatible with the systems in which they are utilized. Since they occupy a very little space in the axis of pipes or tube which prevails lesser or not at all resistance to the liquid flow when the valve is opened.
The structure of a stainless steel gate valve includes a wheel-like rotating knob which tightens the gate opening when rotated clockwise and opens the pipe passage for the flow when rotated in the opposite direction. The two-way opening that serves as the entrance and exists to the liquid are the design specifications that make the apparatus totally compatible with the fluid substances.
Types of the Gate Valve
Depending upon the practical use of the stainless steel gate valves in the fluid controlling systems, their usability and implementation are different in distinctive situations. To satisfy the need of a gate valve in all kinds of situation, the gate valves are distinguished in different types that include:
· Wedge gate-valve: these valves are utilized in the piping and tubing purposes of the industrial structures. The main task of the design is to open and close the passage of the liquid flow.
· Knife gate-valve: they are effective in situations that require applications of the liquid flow in large-sized pipe works. Unlike the conventional gate valve that only provides the facility of opening and closing the passage of the liquid, these valves provide partially open passage for the liquid to pass through.
· Parallel side gate valve: they are mostly used in designs that have the factor of thermal expansion and has to deal with the steam. They are highly recommended in the super hated and saturated systems.
Flow Regulation with Globe Valves
The globe valves are designed on the basic principle of liner or translator motion, which is assigned to perform two complementary movements of the fluid that are passing through the piping system. These movements include the stopping and starting of the flow by completely removing or entirely spreading the disc in the passage of the flow.
Typically, the use of a conventional globe valve is to isolate and throttle the substance that is flowing through it in the pipelines. Even though it is also recognized that these valves have a slightly higher pressure drop as compared to other gate valves, yet, they are effective in the majority of the applications. In particular, the globe valves are more applicable and highly recommended in regulating the flow of fluids when the factor of pressure drop is not considered as a controlling feature.
The globe valve manufacturers offer the regulatory component of the piping system to control the throttling flow of liquids in the system. The design has a shutter like structure which shuts or removes the disc in the opposite direction to the flow by placing the disc in the fluid stream. This changing in direction when an action is accomplished results in higher resistance to the liquid flow, which results in a higher pressure drop. Therefore, in the case when a higher pressure drop is considered to be a compatible factor, globe valves have their particular importance in the system.
Advantages of Using Globe Valve
As mentioned above, the globe valve is considered to be most effective in the majority of the cases where the flow of liquids are meant to be regulated. In the same manner, there are certain specific advantages of using globe valves to control the fluid flow, counting in:
· The globe valves have a better capability to shut off.
· They are efficient in throttling capability.
· They have shorter stokes in comparison to the gate valve.
· They are available in Tee, Wye, and other angular structures.
· Maintenance is easy.
· The usability of the valve is not dependent on the attachment of the disc, which means that whether the disc is attached or not, the valve will work efficiently.
