Hand Valves(Connecting Tube Diameter:3/8)

Hand valves are devices used to manually adjust the flow direction, pressure, flow rate or another property of a fluid (liquid, vapor or gas). Hand valve bodies are made of materials such as aluminum, steel, stainless steel, PVC and resin. Hand valves are usually connected for use with pipes containing flowing fluids using fittings made of the same material as the hand valve body. Hand valve controls are often made of a different material from the body. The controls come in forms such as knobs, handles and levers. The standard types are 2-way valves with 2 fluid input/output ports and 3-way valves with 3. They are attached in accordance with the direction of fluid flow. There are many different hand valve models designed to connect to different pipe diameters and support different operating pressure ranges. There are also different fitting types such as screw-in, flange and welded fittings, so each hand valve model should be selected to match the operating environment.

                              FAQ Hand Valves

                              Question: What is a hand valve and its functions?
                              Answer: A hand valve is a manually operated device used to control the flow of fluid (liquids or gases) in a system. It consists of a handle or lever that, when turned, adjusts the position of an internal mechanism to either open or close the valve. Hand valves serve to regulate fluid flow, isolate sections of a pipeline for maintenance, and control pressure. They find application in various industries such as plumbing and industrial processes.
                              Question: When should you use the hand valve?
                              Answer: Use a hand valve when manual control of fluid flow is necessary. It's employed to start, stop, or adjust flow rates in systems requiring human intervention, such as emergencies, maintenance, or precise adjustments. Hand valves are useful when automation isn't feasible, during equipment servicing, or when immediate response to changes is needed. They offer a simple and reliable means of flow regulation in various industries.
                              Question: What are the advantages and disadvatages of hand valves / manual valves?
                              Answer: Advantages of hand valves (manual valves) include simplicity, reliability, and cost-effectiveness. They offer precise control and immediate response during emergencies or maintenance, making them suitable for small-scale applications. However, they can be slower to operate compared to automated valves, require physical presence for adjustments, and might not be suitable for large-scale or continuous processes. Additionally, potential human error in operation and limited remote control are notable disadvantages.
                              Question: What are the common materials used for valves?
                              Answer: Hand valves are commonly constructed from materials such as brass, stainless steel, cast iron, bronze, and plastic (such as PVC or CPVC). The choice of material depends on factors like the type of fluid being handled, pressure requirements, temperature conditions, and corrosion resistance. These materials ensure durability and compatibility with various applications across industries like plumbing, industrial processes, and water treatment.
