The GULDE 5400 series globe control valves employ advanced valve design technology, offering a diverse range of types and comprehensive specifications, with exceptional control performance. They are widely utilized across various industries for fluid control, providing customers with superior performance and reliability.
A variety of valve body styles are available for selection, with size ranges from NPS1 to NPS12, capable of meeting the diverse requirements of both standard and high-pressure conditions. The temperature range spans from a minimum of -101°C to a maximum of 593°C, enabling customers to effortlessly select the configuration that best suits their process requirements and perfectly addresses pipeline layout demands.
The excellent flow path design and optimization of the 5400 series control valves provides you with sufficient flow capacity. This series of control valves has been extensively flow tested and evaluated for reliability and durability.
Balanced and unbalanced spools can be selected to meet the needs of different clean media conditions. A variety of sealing forms to adapt to different working medium temperature. A variety of valve body and internal materials can be selected, corresponding to different chemical properties of the media.
A variety of spool sealing structure, in order to ensure the sealing at the same time to meet the needs of different temperatures; multi-stage graphite sealing ring, in the 593 ° C working temperature to achieve class IV sealing; special sealing structure can be in the 593C working temperature to achieve class V sealing.
The standard stem packing for the 5400 series is PTFE V-ring packing, which is suitable for valve internal temperatures up to 450°F (232°C). For higher temperatures, graphite packing is available. In addition, Fisher's patented ENVIRO-SEAL packing system is available for improved stem sealing, with a wide selection of packing materials to provide excellent sealing performance in virtually any application. Complies with stringent emission control requirements.
Strict quality control and performance testing ensure the high reliability and durability of Gulde 5400 control valves. Gulde 5400 control valves have passed ISO9000, TS and SIL certificates.
The 5400 series control valves offer a variety of sizes, end connection styles, and valve body styles to choose from, capable of meeting the majority of piping requirements. Featuring a quick-change cage trim design, the flow characteristics of the valve can be altered by simply replacing the valve cage without the need to change the plug and seat. Additionally, the balanced plug structure allows for the smallest possible actuator selection and the lowest cost; standardized trim sizes enable the disassembly and replacement of internal components without the need to replace the valve body, significantly reducing maintenance and upgrade costs for the internals, and increasing the valve's operating time.
For NPS 12 valves, a suspended valve cage design structure is adopted to eliminate the impact of medium temperature on the thermal expansion of the valve cage, thereby removing the influence of thermal expansion on the valve seat and sealing, and better ensuring the internal sealing performance of the valve.
