Normally open modulating element with shuttle
A normally open modulating element, used as a restrictive compensator, ensures a constant pressure drop across an external orifice to create a pressure compensated flow control. The resulting flow remains constant regardless of variations in upstream or downstream pressure.
A ball shuttle connects the after orifice signal from the higher of port 3 or 4 to the pilot area.
- The shuttle features hardened steel balls and seats for excellent wear characteristics and contamination tolerance.
- The single ball shuttle allows for the decay of the pressure signal when both load ports drop to a lower pressure.
- All ports will accept 5000 psi (350 bar).
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
