ABVS air x spring actuated ball valve solves fertigation challenge
A southern grow operation needed an automatic valve for remote fertigation pipelines where compressed air and electricity were unavailable . The valve had to close when water supply pressure dropped below operational levels to prevent excessive nutrient concentrations from harming the crop .
The grower used a Series ABVS Air x Spring Actuated Ball Valve with common tubing lines , substituting water pressure for compressed air on the “ air to open ” side of the actuator . When water flow is diverted from the central control system , the 40 PSI line pressure automatically opens the valve ,
allowing nutrients to flow to the eductors . When water is diverted elsewhere or the pump is turned off , the line pressure drops below 40 PSI , and an isolated spring on the “ spring to close ” side of the actuator automatically moves the valve to a fully closed position , protecting the plants .
Bosch Rexroth and Petrolvalves collaborate on subsea valve electrification
Bosch Rexroth AG and PetrolValves S . p . A . have signed a Memorandum
of Understanding to collaborate on the electrification of subsea
process valves with high Safety Integrity Level requirements , such as Subsea Safety Isolation Valves ( SSIV ). They are working on a solution that connects PetrolValves subsea valves with the Rexroth actuator eSEA Drive , which operates via a simple 24 V DC electric power supply . This development aims to reduce the investment and operating costs of subsea systems for captured carbon storage ( CCS / CCUS ) and safe transport of offshoreproduced green hydrogen ( H2 ).
The eSEA actuators developed by Bosch Rexroth cover all safetyrelevant movements at water depths of up to 4,000 meters and are an economical alternative to traditionally used hydraulically driven actuators . The companies have already implemented this solution using an eSEA Drive to electrify a subsea 5 ’’ gate valve , with a full-scale prototype currently in the final phase of qualification tests to reach Technology Readiness Level ( TRL ) 4 by mid-2024 .
Kent secures FEED contract from INEOS
W & O signs three-year valve supply agreement with Vard
Kent has been awarded a key Front- End Engineering Design ( FEED ) contract for the INEOS Hejre project in Denmark . This prestigious award was won in a competitive bid . According to Kent , the company was chosen because of its extensive expertise and capabilities in the subsea and offshore sectors . The Hejre project , an offshore High Pressure High Temperature ( HPHT ) development , is in the Danish portion of the North Sea . It is planned as a tie-back to the South Arne field , utilizing the existing Hejre jacket structure . Kent ’ s responsibilities under this contract include the complete FEED design for the pipeline , tie-in
spools , retrofit risers , and subsea power & fiber optics cable . Usman Darr , Engineering and Consulting Managing Director for the UK at Kent , expressed his enthusiasm about the project , stating , “ We are thrilled to continue our partnership with INEOS Energy Denmark on the Hejre project . Having successfully completed the pre-FEED for the full project scope , this new phase allows us to further demonstrate our robust FEED capabilities and deep understanding of the unique challenges in subsea and offshore engineering , particularly in the challenging conditions of the North Sea .”
W & O has reached a three-year supply agreement with Norwaybased ship designer and builder Vard , a member of the Fincantieri Group . W & O will provide technical support to Vard ’ s design and engineering departments , covering valve challenges on newly built vessels and delivering valves , actuationand instrumentation packages to Vard in Norway , Romania and Vietnam . Vidar Hoel , W & O ’ s technical project manager based in Ålesund ,
Norway , will lead the technical support , coordinating a W & O project team of specialists based in the Netherlands , Romania and Singapore . W & O ’ s international network will support Vard with an efficient valve supply chain . Vard will also be able to utilize W & O ’ s data management and radio frequency identification ( RFID ) tagging systems , which create an easily accessible history for each critical valve installed on a vessel .
