Manual valves are
mechanical devices
Manual valves are mechanical devices that regulate the flow of fluids or gases in a pipeline or system. They are operated by hand, and their design allows for accurate control of the flow rate and direction. Manual valves are widely used in various industries, including petrochemicals, oil and gas, water treatment, and many others. In this article, we will discuss the types of manual valves , their applications in petrochemicals, and some of the leading brands in the market.
Types of Manual Valves
There are several types of manual valves, each with its unique design and function. The most common types of manual valves include:
Globe Valve
Globe valves are designed to regulate the flow of fluid in a pipeline. They have a spherical body with an internal baffle that controls the flow rate. Globe valves are commonly used in applications where precise flow control is required.
Gate Valve
Gate valves are designed to provide full flow when fully open and complete shutoff when fully closed. They have a flat or wedge-shaped gate that slides into the valve body to control the flow rate.
Ball Valve
Ball valves have a ball-shaped disc that rotates within the valve body to regulate the flow rate. They provide quick opening and closing action and are commonly used in applications where fast flow control is required.
Butterfly Valve
Butterfly valves have a disc-shaped body that rotates within the valve body to regulate the flow rate. They are commonly used in large diameter pipelines and provide quick opening and closing action.
Check Valve
Check valves allow fluid to flow in one direction only and prevent backflow. They are commonly used in applications where backflow prevention is essential, such as in pumps or compressors.
Applications in Petrochemicals
Manual valves are widely used in petrochemicals for various applications, including:
Isolation
Manual valves are used to isolate sections of pipelines or equipment for maintenance or repair. They provide a means of shutting off the flow of fluids in a pipeline or system.
Control of Flow Rate
Manual valves are used to regulate the flow rate of fluids in pipelines. They are commonly used in petrochemical plants to control the flow of chemicals, gases, and other fluids.
Pressure Regulation
Manual valves are used to regulate the pressure of fluids in pipelines.They are commonly used in petrochemical plants to control the pressure of gases, liquids, and other fluids.
Backflow Prevention
Manual valves are used to prevent backflow in pipelines. They are commonly used in pumps and compressors to prevent the reverse flow of fluids.
