Single-seat globe valve with stainless steel construction and extended bonnet. ET-C and EWT-C valves feature pressure-balanced design, while EZ-C valves use an unbalanced design. These cryogenic valves are suitable for throttling or on/off control of liquids and gases at temperatures as low as -198°C (-325°F).
Simple structure,easy maintenance. Top-entry designs allows for in-line maintenance, enabling quick removal of the trims such as cage, plug and seat ring from the top without removing the valve body from the pipeline. The packing box design allows for actuator replacement without depressurization.
Hardened stainless steel trim improves wear resistance and extends service life. Precision-machined trim ensures smooth operation. ET-C and EWT-C's rugged Cage guidance ensures smooth travel of the plug throughout its entire stroke, reducing vibration and mechanical noise.
High flow capacity. Streamlined flow passages provide approximately 30-40% higher flow capacity compared to single-seat globe valves of the same size. For the same flow capacity, a smaller valve can be used, saving valve investment.
Multiple trim options available, such as noise reduction and anti-cavitation trims.Interchangeable trim with other easy-e series models allows for easy modification of flow characteristics and capacity, reducing spare parts inventory and investment.
ENVIRO-SEAL™ packing systems improve stem sealing performance and help prevent process fluid leakage. These packing systems utilize dynamically loaded PTFE or graphite ULF packing, reducing packing maintenance.
These valves underwent extensive cryogenic testing during design development, eliminating the need for costly cryogenic testing for most applications, resulting in faster delivery and lower costs.
Rugged metal seats. Metal-to-metal seats are designed and manufactured to provide long-lasting, reliable, tight shutoff at both ambient and cryogenic temperatures without the need for periodic lapping. This reduces the need for soft seats, even in applications with stringent shutoff requirements.
