CLOSED CENRE HYDRULIC SYSEM WIH VRILE DISLCEMEN UM UOMIC ROION SEED CONROL VLVE S M G HMG HWG valve It is recommended to install DYNSE hydraulic generator to a closed centre hydraulic system of an excavator (see diagram above) without pressure compensator, using only a -valve of required capacity. Installed to a closed centre hydraulic system of a modern excavator, pressure compensator may cause certain deceleration of machine s movements and functions when the priorised flow to the generator is on - pls. consult DYNSE s experts! For all other carriers with closed centre hydraulics (fire trucks etc.) an installation of DYNSE hydraulic generator can be made using a complete V SE valve. 2 DYNSE OY, Menotie 3 el.: DYNSE RIORIY VLVE V-SE 3/4 - /4 INSLLION ND USE GE 8 / 4

9 When an excavator s engine is on without any executor being used, a hydraulic pump levels to the idle mode, producing the flow conditioned by the hydraulic system of a machine. OERION Q2 2/24 VDC Q DYNSE hydraulic generator is started by activating a solenoid valve of -valve, when hydraulic fluid flows in circuit Q through pressure compensator and -valve. Flow limiting valve permits only the pre-adjusted throughflow when an excessive fluid goes to the main pressure line (Q-Q2). ressure compensator changes it s throughput capacity being controlled by -signal. Hydraulic pump adjusts it s output capacity in accordance with the mentioned -signal as well as with the -signal of the machine s hydraulic system. ressure relief valve of -valve protects the hydraulic generator against damaging by directing the hydraulic fluid to the tank () if pressure rises over the limit. When any other hydraulic operating unit (cylinder, motor, O etc.) is being actuated, C-SE, having ensured demanded and RIORISED hydraulic flow to the DYNSE unit (), opens main supply line directing requested hydraulic flow for the corresponding function. Operation of a pressure compensator is controlled by a -signal according to a current capacity request. If controlled flow () for DYNSE-unit is not requested, solenoid valve closes corresponding circuit and all the hydraulic flow is at system s disposal. Q2 CONROL VOLGE = 0 l/min Q = 0 l/min When the compressive force of hydraulic flow in main supply line exceeds the spring force of C SE, the incorporated valve of pressure compensator closes tightly excluding leakage flow.

When fitting a pressure compensator is ESSENIL that the bolts are tightened to the recommended torque value and in the correct sequence. Neglecting this may cause the risk of either the bolts working loose resulting in oil leakage (not tight enough), or damage to and possible shearing of the bolt (over tightened). he tightening is to be made in two steps according to the sequence sketched below. First tighten all bolts app. to /2 of rated torque and then carry out the tightening up to necessary. 4 ightening torque values can be found from an engineering handbook according to the bolt s size, 3 2 thread type and strength class.

Depending on the operating temperature, following mineral hydraulic oils are recommended: ISO VG 32S for oil s operation temperature up to 70 C; ISO VG 4S for oil s operation temperature up to 80 C; ISO VG 8S for oil s operation temperature up to 90 C. Synthetic and bio-oils can be used as well if their viscosity characteristics and lubricating efficiency are corresponding to above mineral oils. utomatic transmission fluids and even engine oils can be used, provided that they are allowed to be used in hydraulic system of your carrier machine. o use special hydraulic fluids a with DYNSE equipment, please be kindly requested to contact nearest DYNSE representative for an advice. SFEY RECUIONS he pressure in hydraulic fluid circuit is considerably high. hereat the technical condition of your equipment should be under constant scrutiny. Especially couplings, valves and hoses should be maintained tight and clean as well as kept under constant observation. Hydraulic leakages must be rectified immediately to avoid injuries caused by pressure and hot oil blowouts. Follow all your local safety instructions related to the high pressure hydraulics. Hydraulic system of a carrier machine should be maintained according to the service program. In order to exclude possible accidents, it is not allowed to clean or inspect V SE valve when hydraulic fluid circuit is pressurised. rior to any cleaning, inspection and service hydraulic system of your carrier machine must be stopped and all hydraulic fluid circuits dissipated. lways wear appropriate clothing and safety equipment such as goggles, ear protection and safety shoes at all times when maintaining the V SE valve. eware of machinery parts warmed by hot hydraulic oil.
