The Function of Valves Pressure Bypass Valves
A natural occurring object or manmade device, valves are simple structures that control or direct the flow of a fluid. In order to manage gases, liquids, fluidized solids, and slurries, valves can open, close, and partially obstruct flow. This allows a fluid to flow in the direction from higher pressure to lower pressure when necessary. A simple yet ancient fitting utilized by man, valves have evolved to suit numerous applications with their wide array of variations and types. Used in residential, commercial, and industrial settings, modern valves are an essential tool that vary in design to cater towards an individual purpose.
Found in almost all industrial settings aiding in their respective fields, valves typically come in 0.1 mm to 60 cm sizes. With the exception of some valves exceeding 5 meters in diameter, most are generally smaller in size and inexpensive to manufacture. That being said, as valves are diverse in implementation, they are generally classified by their process of actuation: hydraulic, pneumatic, manual, solenoid, and motor. As such, they are commonly constructed with a body and bonnet made from plastic, brass, bronze, gunmetal, cast iron, steel, alloy steel, and stainless steel. These components then serve as the primary housing units for all internal parts of a valve and their fluids.
Through regulating the passage of fluids, in regard to actuating a valve for the purpose of obstructing or permitting flow, the control mechanism for this device can either be manual or automatic. Conventionally known as the “handle” for manually actuated valves, these devices are located outside of the valve body. Some valves may also come without actuators constructed within the valve body, allowing the fitting to automatically control the flow of fluids from within. Other common components within differing valve types include ports, discs (or valve member), seats, stems, gaskets, and springs.
Pressure bypass valves, in particular, are installed to control inlet or upstream pressure along a bypass line of piping. Essentially acting as a relief valve to support excessive flow, bypass valves function as backup lines for pressure reducing valves and steam traps. Essential for their robust maneuvering of fluids, bypass valves incorporate fluid control dynamics to allow the continual flow of a fluid when replacing or supplementing the performance of equipment. This provides ample time for fine-tuning any equipment while isolating parts of the piping that can interfere with any processes at hand. Depending on the performance of the piping and the specific substance flowing within, these components are capable of overseeing a range of pressure, flow, and resistance types. Some steam trap systems also utilize built-in bypass parts, although they are not automatic as compared to the aforementioned valve actuators. Needing to be actuated by a handle, built-in bypass valves are unable to function unless physically activated and cannot operate when being replaced.
