A new range of ball valves is claimed to offer important advances in renewable energy applications, including more accurate flow control that translates into better performance with solar thermal plants and wind turbines using hydraulic controls.
The new components, from Aalberts integrated piping systems (IPS), a specialist in advanced integrated piping systems for the distribution and control of liquids and gasses, include the “Apollo”® v-port series control valve (pictured, opposite).
In the renewable energy industry, these v-port ball valves are used to regulate the flow of fluids in systems such as solar thermal plant. They ensure precise management of heat transfer fluids or hydraulic oils, optimizing system performance and efficiency. Their accurate flow control capabilities help maintain consistent operation and reliability, contributing to more effective and stable energy generation.
The “Apollo”® v-port is said to provide improved control over fluid dynamics, reducing operational costs and enhancing system performance. Additionally, it offers significant energy savings, contributing to cost-efficient operations, says the firm.
Key features include a three-piece construction with enclosed fasteners for easy maintenance and repair, standard port and full port options for versatility, and stainless steel trim and hardware for corrosion resistance. The pressure-balanced solid ball reduces operating torque and ensures smoother operation, while compression-controlled spiral wound gaskets improve sealing and reduce leakage. The anti-blowout one-piece bottom entry stem enhances safety by preventing stem ejection under pressure, and the statically grounded ball, stem, and body reduce the risk of static electricity buildup.
The valve features live-loaded stem packing, which maintains seal integrity and reduces maintenance frequency. It also includes adjustable graphite stem packing for in-situ adjustments and a fully machined ISO 5211 mounting pad for standardized actuator mounting. Additional features include fire safety compliance with API 607 standards, CE marking for adherence to European regulations, and a 250 psig saturated steam rating for high-temperature applications.
The parts are manufactured at Aalberts IPS’s facility in Conway, South Carolina.
