Normally open modulating element with shuttle

Capacity: 15 gpm60 L/min. | Cavity: T-21A
LPDS : Normally open modulating element with shuttle
Technical Features [ + ]

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.
