Fixed setting, 2.3:1 pilot ratio, standard capacity counterbalance valve
SERIES 1 / CAPACITY: 60 L/min. / CAVITY: T-11A
3-Port Non-vented, Fixed Setting
Fixed-setting, 3-port counterbalance valves with pilot assist function similarly to the adjustable versions except the
fixed setting is pre-set to a nominal value. These fixed-setting valves are meant to control an overrunning load. The
check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-
assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief
valve at a rate determined by the pilot ratio.
Other names for this valve include motion control valve and over center valve.

The maximum recommended load pressure for the M range is 3600 psi (250 bar). The highest cracking pressure for the M range will be less than 5600 psi (390
bar).
The maximum recommended load pressure for the V range is 2450 psi (170 bar). The highest cracking pressure for the V range will be less than 3800 psi (260 bar).
The maximum recommended load pressure for the X range is 2700 psi (190 bar). The highest cracking pressure for the X range will be less than 4200 psi (290 bar).
The maximum recommended load pressure for the Z range is 3170 psi (220 bar). The highest cracking pressure for the Z range will be less than 4900 psi (340 bar).
Note: The pressures listed under RANGE are approximate, mean values and should not be used for inspection purposes.
Note: The percentage difference between the cracking and reseat values for the fixed and adjustable versions of this valve are identical. However, the cracking
point for the adjustable control can be set via the adjustment mechanism to within +/- 50 psi (3,5 bar) of the specified value. In the case of the fixed-setting version,
