  • S-Class Block & Bleed Valves

    S-Class Block & Bleed Valves

    The Gosco Block and Bleed Valve stands on top of its class by providing the unique components featured in a standard S-Class valve, combined with cutting edge live-loaded seat technology. Gosco Valves' extended bonnet, S-Class sealing system, Clearview mounting pad, soft seats and exotic alloy options make these block and bleed valves extremely versatile, enabling them to tackle the toughest severe service applications.

  • Configurations


    A single block and bleed configuration is used when the operator wants to check the integrity of the seats in a valve. With the valve in the closed position, you can pressurize each end, and open up the bleed valve to see if the seats are working properly. A double block and bleed with an integral body (one valve, two balls, four seats and a bleed valve) is used for applications where there is limited space, requiring a double block and bleed valve with reduced dimensions.

  • 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.

  • Stem Sealing System

    Stem Sealing System

    The core of our patented stem sealing system is the dual live-loaded packing. To eliminate side loading on the packing, we've added two stem guides to support the stem 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 stem sealing system has been tested by TUV, and exceeds all current and projected fugitive emission standards.

  • 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" stem 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.
