DIRECTIONAL VALVES

LS10-41 Inverted Shuttle Valve

DESCRIPTION

A screw-in, cartridge-style inverted shuttle valve, which can be used to help protect

against brake or steering failure in the event of loss of pressure in either one of two

accumulators.

OPERATION

If one accumulator fails, the LS10-41 will shift over to protect the good one. All ports

are connected in neutral. When pressure at one of the two load ports exceeds the

other, the poppets shuttle to allow bi-directional ﬂ ow between other two ports. Typical

applications include braking and steering circuits.

Note: Port

➀ should be blocked.

FEATURES

• Hardened work surfaces.

• Industry common cavity.
