Mechanical valves are critical components used in piping and fluid systems to control the flow, pressure, and direction of liquids or gases. These devices operate by opening, closing, or partially obstructing passageways to regulate the movement of fluids within mechanical, plumbing, or HVAC systems. Available in various types—including gate valves, globe valves, ball valves, butterfly valves, and check valves—each is designed for specific functions such as isolation, throttling, or backflow prevention. Mechanical valves are constructed from durable materials like brass, stainless steel, cast iron, or PVC, depending on the fluid type and operating environment. Manual, motorized, or pneumatic actuators can be used to control them, allowing for both simple and automated operations. Valves play a crucial role in ensuring system efficiency, safety, and reliability across residential, commercial, and industrial applications.
