  • S-Class Cryogenic Valves

    S-Class Cryogenic Valves

    S-Class Cryogenic Valves can withstand temperatures of -200 °C/ -328 °F and have a minimum 12" bonnet extension to protect the actuator and handle from the ice ball. The valve features the patented S-Class Shaft Sealing System, a detachable bonnet, and TFM-1600 seats (-200 °C/-328 °F.) If safety is a concern, every S-Class Cryogenic Valve has a fully grounded shaft, and a drilled ball to relieve pressure. A bolt-on retrofit kit is available.

  • Cryogenic Extension

    Cryogenic Extension

    In cryogenic applications, an ice ball develops around the valve. It is often so large, it covers the handle, making it impossible to open/close the valve. S-Class Cryogenic Valves feature a minimum 12” bonnet extension that extends the handle/actuator outside the ice ball. As well, the extension naturally creates a gas pad that prevents the cold media from shrinking the packing. This is why cryogenic valves should be installed at 45° or more.

  • Bolt-on Retrofit Kit

    Bolt-on Retrofit Kit

    Not only is an S-Class Cryogenic Valve designed for high performance, but for convenience as well. A 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 shaft, and bonnet assembly with new packing.

  • Exotic Trim

    Exotic Trim

    An S-Class Cryogenic Valve can be custom fitted with several exotic trim options. Monel is a non-sparking metal, making it perfect for oxygen service. In addition to machining the ball out of Monel, we design it so that all edges in the process flow are rounded. This reduces velocities that can cause explosions in an oxygen line. A Niton analyzer is used to do full Positive Material Identification (PMI) on all exotic trim options.

  • 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.

  • Arcuate Cut Ball

    Arcuate Cut Ball

    An arcuate cut is a profile in the ball that reduces velocity as the valve opens and closes. When a standard ball valve is in the first and last 10° of opening/closing, velocities are very high (especially in the corners), and erosion occurs. With an arcuate cut, the opening on the ball is almost three times as large. This reduces the velocity by spreading out the flow through a larger opening, which reduces wear on the ball and seats. BORONIZING must be used to harden arcuate cut profiles because HVOF coatings are line of sight and can not evenly coat the ball.

  • Encapsulated Seats

    Encapsulated Seats

    S-Class Valve encapsulated “Soft" seats are used for high cycle, abrasive, high pressure, cryogenic and high temperature applications. Our live-loaded design completely encapsulates the "Soft" insert on all four sides, to minimize its exposure to the process. The “Soft” inserts are held in place by “barbs” on the metal outer carrier, to prevent cold flow. The assembly is then compressed to 3-4 times the maximum pressure rating of the valve, so that the insert takes a compression set. Afterwards, the seat profile is machined and match lapped to the ball. For abrasive/high pressure drop applications, a Devlon insert can be used with a boronized ball.

  • Bi-Directional Sealing

    Bi-Directional Sealing

    The S-Class Cryogenic Valve design has an option for a drilled ball on the upstream side, or a completely bi-directional design that relieves pressure in the body/ball cavity. It doesn’t have a “Preferred Direction” and seals bubble tight in both directions with both a full pressure differential, OR a 1 psig differential. Since the seats are live loaded with wave springs, any pressure build-up in the valve cavity, will collapse the spring on the low pressure side, and relieve the pressure in the ball/body cavity.
