The Classification Of A Manual Valve
- Gate valves serve to provide on/off control in piping systems. They have a gate-like structure that goes up and down to control the flow. These valves are best suited for functions that require minimal pressure loss and free non-stop flow.
- Globe valves are perfect for applications that need constant change in flow because they facilitate very precise throttling control. These valves have a spherical body and are equipped with an internal disc that moves sideways concerning the hole through which the fluid flows.
- These valves offer quick operation, durability, and tight sealing, making them ideal for high-pressure and high-temperature applications. Ball valves use a rotating ball with a hole to regulate fluid flow.
- A butterfly valve has a rotating disc for controlling the flow of the liquid. This valve is lightweight, cheap and is preferred in large pipes where space is an issue.
- As the name suggests, a check valve allows the flow in only one direction, stopping the backflow. These valves are popular in water treatment plants, pumps, and other industrial machinery with numerous systems that need direction flow control.
- Using a flexible diaphragm to control fluid flow makes a diaphragm valve. These valves are common in the industries dealing with corrosive, abrasive or high-purity fluids like in pharmaceutical and chemical processing plants.
