Valve Assemblies

Types of Valves

• Valve assemblies are critical components in many industrial applications, including those in the valve and pump assembly plants. Different types of valves are used depending on the specific requirements of the system they are integrated into. The main types include:
• Gate Valves: Gate valves use a gate or wedge that moves up and down to start or stop the flow of fluid. They are designed for fully open or fully closed service. Commonly used in pipelines where a straight-line flow and minimum restriction are desired. They are ideal for isolating sections of a pipeline or system.
• Ball Valves: Ball valves utilize a spherical ball with a hole through the middle. When the hole aligns with the flow direction, the valve is open; when turned 90 degrees, it is closed. Suitable for shut-off and control applications. They are widely used in industries that require tight sealing and reliability.
• Butterfly Valves: Butterfly valves have a disc that rotates to allow or restrict fluid flow. The disc is positioned in the center of the pipe and connected to an actuator on the outside. Ideal for applications that require quick shut-off and are often used in systems where space is limited and large valves are not feasible.
• Check Valves: Check valves allow fluid to flow in one direction only, preventing backflow. They typically have a hinged gate or a ball that moves to block reverse flow. Commonly used in pump systems to prevent reverse flow and protect equipment from damage.
• Globe Valves: Globe valves use a linear motion to throttle flow. The valve seat is parallel to the line of flow, and the disc moves perpendicular to the seat. Used for regulating flow in pipelines, especially where precise control is required.
