Valves are essential components in fluid control systems, and they come in various types designed for specific applications. Common valve categories include Air Valves, Angle Valves, Angle Throttle Valves, and Angle Type Globe Valves, each serving different purposes such as regulating flow or providing shut-off functions. There are also specialized valves like Ash Discharge Valves, Suction Valves, and Auxiliary Valves used in industrial and mechanical systems.
Other common types include Butterfly Valves, which can be non-slam or equipped with gear actuators, and Gate Valves, available in double disc or single disc configurations. Exhaust Valves, Drainage Valves, and Safety Valves are crucial for pressure relief and system protection. Electric Actuated Valves, Diaphragm Valves, and Check Valves are widely used in automated and precision-controlled environments.
Additional valve types include Plug Valves, Ball Valves, and Globe Valves, often made from materials like stainless steel, cast iron, or specialized alloys. Components such as the body, bonnet, disc, seat, stem, and seals are critical to the functionality and durability of these devices.
In terms of specifications, valves are rated based on factors like pressure, temperature, material compatibility, and connection types. Standards such as flange, socket, and threaded connections define how valves integrate into piping systems. Materials used range from metals like nickel-chromium steel and Monel to elastomers like NBR rubber and PTFE, ensuring suitability for diverse operating conditions.
Testing parameters like maximum allowable pressure, temperature limits, and performance standards ensure valves meet safety and operational requirements. Whether used in power plants, chemical processing, or water treatment, valves play a vital role in maintaining system efficiency and reliability.
