  • M-Class Cryogenic Valves

    M-Class Cryogenic Valves

    M-Class Cryogenic Valves are designed to withstand temperatures of -270 °C/-454 °F and have a minimum 12" bonnet extension to protect the actuator and handle from the ice ball. The valve features the patented M-Class Stem Sealing System, a detachable bonnet, and metal seats. If safety is a concern, every M-Class Cryogenic Valve has a drilled ball to relieve pressure as well as a fully grounded stem. A bolt-on retrofit kit is available as well.

  • Cryogenic Extension

    Cryogenic Extension

    In cryogenic applications, a large ice ball develops around the valve. On a traditional ball valve, the ice ball is often so large, it completely covers the handle or actuator, making it impossible to open/close the valve. M-Class Cryogenic Valves feature a minimum 12° bonnet extension that keeps the handle and actuator outside the ice ball. This not only allows you to open/close the valve easily, but it also allows you full access to the packing adjustments.

  • Bolt-on Retrofit Kit

    Bolt-on Retrofit Kit

    We not only design the valve for high performance, but we also design M-Class Cryogenic Valves for convenience. The bolt-on retrofit kit is used when the soft goods have to be replaced in the valve. The customer simply has to remove the bolts holding the cryogenic extension to the body, and send the bonnet assembly and cryogenic extension to Gosco Valves. We will return a bolt-on retrofit kit that includes a pre-tested stem, and bonnet assembly with new packing.

  • Oxygen Cleaning

    Oxygen Cleaning

    Oxygen is extremely explosive and even a tiny particle could cause a spark, potentially causing an explosion in the line. Valves in oxygen service must be oxygen cleaned and bagged in order to guarantee that the valve is 100% free of debris. Special facilities and procedures including a positively-charged clean room, approved cleaning solutions, and ultraviolet inspection lighting are available at Gosco Valves if you require oxygen cleaning.

  • Metal Seats

    Metal Seats

    Abrasive applications quickly wear the trim on regular ball valves, so using the right custom configurations can extend the life of your ball valve by years. We offer several custom trim options, including coatings (e.g. chrome carbide/tungsten carbide on 410SS), diffusion processes (e.g. boronized Inconel/Hastelloy) and ceramics (e.g. silicon nitride, aluminum zirconia). Every trim option has its advantages and disadvantages, so knowing which configuration to use is the key to our success.

  • Exotic Trim

    Exotic Trim

    An M-Class Cryogenic Valve can be custom fitted with several exotic trim options. Monel trim is a popular option because it is a non sparking metal, making it perfect for oxygen service. In addition to machining the ball out of Monel, we design the ball so that all edges in the ball opening are rounded. This reduces velocities that can cause explosions in an oxygen line as well.

  • 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. The fee is based on accelerated engineering and design, supplier expedite charges, air freight, extra manpower and other associated costs. What does this buy you?
