Like me, most of you would think of how ‘valves’ make our lives more comfortable. By the end of this article, you will have your answers.
I know many of you are reading this blog with your N95 mask on. But take a moment to examine the valves used in the mask. While exhaling, these valves keep the surface area of your face cooler inside the mask. When we exhale, it releases moist air and closes when we inhale.
We have already adapted to a new normal to deal with COVID 19 pandemics, and these masks are saving millions of lives. Keep your masks on while you’re out. Here are a few other common appliances where these valves perform magic.
In our smart homes, we simply turn a conventional TRV (thermostatic radiator valve) in our rooms to the desired temperature and we experience those cool breezes. As if these cool breezes are relaxing us, we just sit and enjoy them. These smart TRVs can manage from anywhere, no matter where they are install.
As we drive and adjust our seats to our comfort, these solenoid valves fill in, hold, and release the air from air cushions in seat backs to provide lumbar support. These valves help us to get into a driving position or to relax while driving.
As a result, we are enjoying the magic of these valves almost everywhere we go in our daily lives. By providing comfort in our workplaces, these valves are not just use in household appliances. But also in offices and industries.
Pharmaceutical facilities use these valves to control airflow in air handling units. Water flow in chill water piping, and refrigerant flow in copper piping. To maintain temperature and humidity in offices, comfort rooms, and classified areas, these valves release the refrigerant. Butterfly valves, control valves, check valves, gate valves, globe valves, ball valves, pressure relief valves, and diaphragm valves are commonly use in HVAC systems.
It is pretty self-explanatory what these parts of a valve do.
Classification of Valves
Based on their mechanical motion, valves are classified as follows:
Linear Motion Valves: As in gate, globe, diaphragm, pinch, and lift Check Valves, the closure member moves in a straight line to allow, stop, or throttle the flow.
Rotary Motion Valves: Rotary motion valves are those whose closure member travels along an angular or circular path, such as butterfly, ball, plug, eccentric, and swing check valves.
Quarter Turn Valves: It requires approximately a quarter turn, 0° through 90°, of the stem motion to go from fully closed to fully open on some rotary motion valves, such as a butterfly, plug, and ball valve.
Globe Valve: A globe valve is one of the most commonly used valves in the industry. You must have seen these valves in various applications. They are use to start, top, and regulate the flow of fluid in cooling tower discharge pumps.
Plug Valve: In addition to handling liquids and gases, plug valves are also ideal for handling sludges, slurries, and sludge-like substances. For diverting and throttling applications, 3-way and 4-way plug valves have rotary motions.
Ball valves: Almost anywhere a fluid flow must be shut off, from a compressed-air line to a high-pressure, hydraulic system, ball valves are used. Quarterly turn valves are specifically design to regulate flow in certain situations.
Butterfly valves: A butterfly valve is a quarter-turn valve with circular flaps that swing into and out of the flow stream. Fluids are regulating and isolated in cooling towers, process plants, and wastewater plants using these devices.
Check Valves: Check valves are generally used for controlling fluid flow in one direction only. In gas lines, for air service, and with pumps, they are use wherever fluids must move in one direction.
Diaphragm Valves: Flexible membrane diaphragm valves for managing flow in pipes. Pharma, food, cosmetics, and semiconductor industries mostly use them.
