The WAL Limited Edition series are electron-beam-welded maintenance-free diaphragm accumulators in the WA range. Two high-strength steel caps are welded together enclosing a U-shaped diaphragm. The nearly spherical body shape provides a higher energy density (energy content per mass) compared to cylindrical designs. Gas valve is M28x1.5. Fluid connections available in standard threaded versions including double-thread variants for quick and secure anchoring with external threading and locking nut. Can be installed in any position. Non-repairable construction. Manufactured in accordance with PED 2014/68/EU.
