Fixed setting, 3:1 pilot ratio, load reactive load control valve
SERIES 2 / CAPACITY: 120 L/min. / CAVITY: T-2A
3-Port Non-vented, Fixed Setting
Fixed setting, load reactive, load control valves with pilot assist combine two valves; a check valve and a relief
valve. 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.

TECHNICAL FEATURES
The maximum recommended load pressure for the K range is 2300 psi (154 bar). The highest cracking pressure for the K range will be less than 3350 psi (210 bar).
The maximum recommended load pressure for the L range is 3075 psi (215 bar). The highest cracking pressure for the L range will be less than 4350 psi (300 bar).
The maximum recommended load pressure for the M range is 3850 psi (270 bar). The highest cracking pressure for the M range will be less than 5350 psi (370
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 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 -version, the setting
tolerance can only be maintained within a +/- 350 psi (20 bar) range. Thus for the 3000 psi (210 bar) fixed-setting model, with a rising pressure the valve will open
below 3350 psi (230 bar) and with a falling pressure will reseat above 2500 psi (170 bar). For the 4000 psi (275 bar) fixed-setting model, with a rising pressure the
valve will open below 4350 psi (300 bar) and with a falling pressure will reseat above 3100 psi (215 bar). For the 5000 psi (350 bar) fixed-setting model, with a
rising pressure the valve will open below 5350 psi (370 bar) and with a falling pressure will reseat above 4000 psi (275 bar).
Fixed-setting load control valves can be used to protect cylinder seals in outrigger circuits from damage due to thermal expansion, however, they probably should
not be applied in circuits in which a matched valve setting may be required such as dual cylinder applications.
