    The 1" (DN 25) plunger valve is designed for precise fluid control and offers excellent performance. Flanged plunger valves are widely used in water treatment plants, industrial processes and irrigation systems.


    • Model: ATO-PV-DN25
    • Nominal Pressure: 1.6MPa
    • Material: Carbon Steel
    • Connection Method: Flange connection
    • Medium: Water, steam, oil
    • Applicable Temperature: ≤425℃
    • Weight: 11kg


    • When switching on and off the plunger valve, the plunger moves slowly in the sealing ring and the contact surface is hardly worn.
    • The sealing ring adopts new non-toxic sealing material with strong elasticity and high wear resistance, which is reliable and durable.
    • In the valve between the plunger and the sealing ring using interference fit, thus ensuring the sealing of the valve and eliminating internal and external leakage.
    • When closed, the plunger is inserted into the lower sealing ring to cut off the flow channel.
    • When opened, the plunger is detached from the lower seal ring but remains hidden in the upper seal ring, keeping it isolated from the outside world and preventing leakage.

    Plunger valve application

    Tips: What is a plunger valve?

    A plunger valve is a type of valve that uses a plunger, also known as a piston, to control the flow of fluid through a pipe or channel. The plunger is typically made of a rubber or elastomeric material that creates a tight seal against the valve seat when it is pressed against it.

    When the plunger is in the open position, fluid can flow freely through the valve. When the plunger is moved into the closed position, it creates a seal against the valve seat, stopping the flow of fluid.

    Plunger valves are commonly used in applications where a tight shut-off is required, such as in water treatment plants, industrial processes, and irrigation systems. They are also frequently used in toilet tanks to control the flow of water into the bowl.
