  • S-Class 3-Way Diverter Valves

    3-Way Diverter

    S-Class 3-Way Diverter Valves offer superior reliability in an affordable and readily available package. Our quarter-turn 3-Way Diverter Valves are bottom entry with flow to the left or right ports. We offer a "Single L Port" ball for 180° applications, and a "Double-L Port" ball for 90° applications. The seats are live-loaded so that they seal in both directions, and don't rely on the process pressure to assist with sealing the ball and seats.

  • 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.

  • Shaft Sealing System

    Shaft Sealing System

    The core of our patented shaft sealing system is the dual live-loaded packing. To eliminate side loading on the packing, we've added two shaft guides to support the shaft at the bottom and the top. For a third layer of protection, a fugitive emissions port can be drilled to monitor the areas between the packing sets. Our shaft sealing system has been tested by TUV, and exceeds all current and projected fugitive emission standards.

  • Encapsulated Seats

    Encapsulated Seats

    The S-Class Valve encapsulated soft seats are used for high cycle, abrasive, high pressure, cryogenic and high temperature applications. Our proprietary live-loaded design allows us to completely encapsulate the "Soft" insert on all four sides, leaving only a small section of the "Soft" material exposed for sealing. The soft insert is held in place with “barbs” that preventIt 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. For abrasive applications, it can be used with a boronized, arcuate cut ball.

  • Exotic Alloys

    Exotic Alloys

    Cast or bar stock, Gosco manufactures ball valves out of any metal, even metals that require vacuum casting (like titanium). We are not restricted to creating just the body from exotic alloys, as we can manufacture all components to suit your needs, right down to the bolting. Our engineering team at Gosco Valves has extensive experience in corrosive applications, recommending only the best material to use for your specific application.

  • Extended Bonnet

    Extended Bonnet

    The extended bonnet is perfect for insulated lines as there is at least 2" between the top of the flange and the bottom of the Clearview mounting pad. This allows you to fully insulate the valve and still have access to make packing adjustments, without having to remove the actuator or insulation. The valve shaft flats are also visible, and the actuator is raised away from the elevated process temperatures, preventing damage to the actuator seals.

  • Clearview Mounting Pad

    Clearview Mounting Pad

    Clearview is a combination of a ISO 5211 mounting pad for easy installation of valve accessories, and a CNC machined/cast bracket that guarantees accurate actuator alignment. Packing adjustments can be performed in-line without removing the actuator, and the double "D" shaft gives you a visible indication of the position of the valve. Clearview also raises the actuator from the valve, and acts as a heat sink to protect it from excessive temperatures.
