Claim 3:
4. A system as claimed in claim 1, wherein the control valve further comprises:
a housing within which the spool moves;
a first member located at a first end of the spool and axially movable with the spool; and
a first resilient member biased between the first member and a first stationary member or portion of the control valve,
wherein in the mechanical neutral position of the spool a gap (G) exists between the first member and the housing, and upon pressurisation of the control valve the first member is configured to move towards and abut the housing so as to close the gap (G), wherein upon contact of the first member and the housing the gap (G) is closed and the spool is in the hydraulic neutral position.
