Plunger Valve

Speciality Valve is a trusted Plunger Valve manufacturer in India. A plunger valve is a type of valve used to regulate fluid flow in piping systems. It consists of a cylindrical or conical plunger that moves vertically within a chamber. When the plunger is lowered, it seals against a seat to stop the flow of fluid, and when raised, it allows fluid to pass through. Plunger valves are often operated manually or with actuators and are valued for their precise flow control capabilities, making them suitable for a wide range of industrial applications. They come in various materials, configurations, and sizes to accommodate different operating conditions and fluid types. Plunger valves come in different designs, including straight-through and angle configurations. Straight-through plunger valves have a linear flow path, while angle plunger valves have a 90-degree inlet and outlet, offering easier installation in tight spaces.

Plunger valves are relatively simple in design, making them easy to maintain and repair. They often feature a removable bonnet or access cover for convenient access to internal components. These valves offer excellent throttling capabilities, allowing for precise control over flow rates. The position of the plunger determines the degree of opening, enabling operators to regulate flow according to specific requirements.

How does a Plunger Valve work?

A plunger valve operates by controlling the flow of fluid through a cylindrical or conical plunger that moves within a chamber. When the plunger is lowered, it presses against a seat, blocking the flow of fluid. Conversely, raising the plunger unseats it from the valve body, allowing fluid to pass through. This vertical movement of the plunger, often manually or with an actuator, provides precise control over flow rates. Plunger valves are favored for their simplicity, durability, and versatility, making them suitable for various industrial applications requiring reliable flow regulation.
