  • M-Class 3-Way Diverter Valves

    3-Way Diverter

    The 3-Way Diverter offers superior reliability in a metal-seated package. Configurations include a "Single L Port" ball for 180° applications, specifically for when there is no mix of the media between the two ports, and a "Double-L Port" ball for 90° applications in which mixing is expected to occur between the ports. Whatever the application, the 3-Way Diverter Valve is guaranteed to outperform its competitors and surpass all expectations.

  • Ball Configurations

    3-Way Diverter

    Single "L" (Looking at the ball from the top) Flow direction is bottom entry to the left. Turn 180° and flow direction is bottom entry to the right. A single "L" configuration allows you to have a shut off position at 90°.

    Double "L" (Looking at the ball from the top) Flow direction is bottom entry to the left. Turn 90° and flow direction is bottom entry to the right. With a double "L" configuration, there is always flow going to one side or the other with a mix between.

  • Exotic Alloys

    Exotic Alloys

    If you can cast it, or it is available in bar stock, Gosco can make it in to an M-Class 3-Way Diverter Valve, even with metals that require vacuum casting (like titanium). We are not restricted to making merely the body from exotic alloys, as we can create all components to suit your needs, right down to the bolting. Our engineering team at Gosco Valves have extensive experience in corrosive applications, and we can recommend the best material to use for your specific application.

  • Tripod Mounting Pad

    Tripod Mount

    The patented M-Class Tripod Mount allows you to install the valve at any angle without supporting the actuator, while eliminating actuator misalignment. The three evenly-spaced prongs create a plane, preventing the actuator from rocking. When paired with a CNC machined mounting plate that cannot move left to right or back and forth, the actuator is guaranteed to be aligned correctly. Additionally, the packing can be adjusted without having to remove the actuator.

  • Metal Seats

    Metal Seats

    Abrasive and high temperature applications quickly wear out the trim on Regular ball valves, so using the right custom metal seated configuration can extend the life of your valve by years. We offer all the traditional trim options, such as HVOF coatings (e.g. chrome/tungsten carbide on 410 SS), but our preferred trim material is boronized Inconel 718. It is considerably harder, more wear resistant, can handle temperature shocks better, and is more corrosion resistant than any coating on the market.

  • Encapsulated "Soft" Seats

    Hot Seats

    The M-Class encapsulated soft seats are used for high cycle, cryogenic and medium temperature applications. What makes the our “soft” seats unique, is they are live loaded and the “Soft” material is fully encapsulated on all three sides. It is then compressed to 3-4 times the maximum pressure rating of the valve so that it takes a compression set. Afterwards, the seat profile is machined and match lapped to the ball.

  • Fast Track Service

    Fast Track Service

    What good is an elite custom ball valve if it can't be delivered when you need it? Fast Track, our expedited delivery service is designed to help you meet near-impossible deadlines.
