A plunger valve is a type of valve that uses a plunger or rod to control the flow of fluids or gases through a piping system. The plunger is typically mounted on a stem and is moved up or down to open or close the valve. Plunger valves are often used in high-pressure or high-temperature applications where precise control of the flow is important.
Plunger valves operate using a simple mechanism. When the plunger is in the down position, it blocks the flow of fluid or gas through the valve. When the plunger is raised, the flow is allowed to pass through the valve. The flow can be precisely controlled by adjusting the position of the plunger.
Plunger valves are typically actuated using a manual handle or lever, but they can also be automated using a variety of actuators, such as pneumatic or electric motors. Some plunger valves also incorporate additional features, such as seals or packing, to help prevent leakage and ensure a tight seal.
In summary, a plunger valve is a type of valve that uses a plunger to control the flow of fluids or gases through a piping system. It operates by raising or lowering the plunger to open or close the flow and can be actuated manually or using an actuator. Plunger valves are often used in high-pressure or high-temperature applications where precise control of the flow is important.
