When your operation relies upon fast and efficient connection and disconnect solutions, Stucchi keeps your process on schedule with durable and reliable quick connect and poppet valve solutions.

Hydraulic Poppet Valve

The hydraulic poppet valve designed in our threaded poppet couplers is for open or closed center hydraulic systems. The poppet valve provides positive-stop valving to prevent flow checking, with connection under residual pressure allowed on one side. Save time when switching out equipment lines with our threaded poppet couplers that provide high resistance to pressure in a compact design.
Our threaded poppet coupling products include a wide selection of durable and versatile solutions including:

  • VOF Series

    Read more

    The VOF series threaded poppet couplers provide high resistance to pressure impulses, in a compact design. The VOF’s internal parts are designed to reduce turbulence and pressure drop, and its poppet valve with elastomer seal provides maximum sealing of the couplings when disconnected. A wrench flat on the bodies facilitates the fitting assembly, and the retainer is high resistance carbon steel.

  • VOFX

    Read more

    The VOFX series threaded poppet couplers provide high resistance to pressure impulses and are manufactured with corrosion-resistant 316 stainless steel, in a compact design. Like the VOF, the internal parts of the VOFX are designed to reduce turbulence and pressure drop, and its poppet valve with elastomer seal provides maximum sealing of the couplings when disconnected. A wrench flat on the bodies facilitates the fitting assembly.

  • Wing Style Series

    Read more

    The W series rugged wing nut provides reliable service wherever a coupling is required to connect under pressure with minimum spillage and air inclusion.

  • VLS Series

    Read more

    The VLS series heavy duty screw coupler is a durable product using heavy duty poppet style valves for the sealing mechanism and threads as the mechanical connection. The VLS series couplings feature a particularly rugged design, making them particularly well suited for heavy-duty service conditions, including construction equipment used in extreme off-highway conditions.

  • VD Series

    Read more

    The VD series European screw coupler uses a poppet style valve as the sealing mechanism and threads as the mechanical connection, to ensure connection under residual pressure. The highly versatile, rugged design with highly visible O-ring connected marker makes the VD ideally suited for heavy-duty service conditions and hydraulic systems experiencing pressure spikes or impulses.

  • VR Series

    Read more

    The VR German screw coupler uses a low leakage-style valve for the sealing mechanism and threads as the mechanical connection, to ensure connection with some residual pressure. The rugged design makes the VR particularly well suited for heavy-duty service conditions and a variety of hydraulic applications, including the mobile construction and industrial fields.

The hydraulic poppet valves in the treaded poppet couplers ensure reliable connection under residual pressure, ideal in hydraulic systems experiencing pressure impulses or spikes, serving a variety of hydraulic needs in industrial plant applications. The valves provide reliable performance in heavy-duty conditions, wherever impulses must be managed, or turbulence reduced.
