    A low-priced plunger valves have a size 1/2" bore and a nominal pressure of 1.6 MPa. This carbon steel plunger valve offers excellent performance and reliability to meet your fluid control needs.


    • Model: ATO-PV-DN15
    • Nominal Pressure: 1.6MPa
    • Material: Carbon Steel
    • Connection Method: Flange connection
    • Medium: Water, steam, oil

    • 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: How does a flanged plunger valve work?

     When the handwheel rotates, the plunger is driven by the valve stem in the middle of the hole frame up and down reciprocating movement to complete the valve opening and closing function. In the valve between the plunger and sealing ring using an interference fit, by adjusting the flange bolts in the gland, so that the lateral force generated by the compression of the sealing ring and the valve body in the hole surface and the plunger outer circle seal, so as to ensure the sealing of the valve, to eliminate internal leakage, while the plunger valve opening torque is small, can achieve rapid opening and closing of the valve.
