The Argo Hytos RPEK series sandwich valves, available from PT Hydraulics Australia , are acclaimed for their compact size and versatility, they offer for low flow power pack system applications. The valve series is set above the competition due to its being a stackable valve only 31mm wide per section.
Normally valves can only be stacked up to a maximum of eight sections. The limitation is decided by the assembly bolts which will stretch too far in proportion to their length when the valve is pressurised, thus causing the valve to leak. However, by including an immediate mounting block allowing section to be mounted either side this problem is easily overcome.
With the pressure and tank galleries included, flow through the block to feed the second bank of valves is achieved. Six sections on either side build a 12 bank assembly, however a 16-section valve can be made (2 x 8 sections) with no sub-plate required.
