1 7P 7P DIRECTIONAL CONTROL VALVE WAY POPPET litres/min (8 U GPM) bar ( psi) PILOT OLENOID CAVITY OMITTED FOR CLARITY NORMALLY OPEN NORMALLY CLOED INLET OUTLET APPLICATION To give on-off control of flows of litres/min (8 U GPM) and pressures up to bar ( psi) in any hydraulic system. Can also be used as a high capacity, fast acting, dump valve. PECIFICATION Figures based on: Oil Temp = 4 C Viscosity = 4 ct Rated Flow litres/min (8 U GPM) Working Pressure bar ( psi) OPERATION The normally open or normally closed pilot cartridge controls the vent flow through the main poppet. When in the open mode, pilot flow passes through the orifice in the poppet and the resultant pressure imbalance causes the main section to open. As the movement of the main poppet or spool is not limited by the solenoid stroke, the valves have a flow capacity of litres/min (8 U GPM) with a low pressure drop. Cartridge Material Mounting Position Weight (exc. coil) Working parts hardened and ground steel. External surfaces electroless nickel plated. Aluminium Line mounted.9 kg (4.8 lbs) REVERE PREURE The valves are normally used for the bidirectional control of flow and the integral check valve ensures that the main section will open and pass reverse flow regardless of the pilot mode. The normally closed valve is typically used in line to an actuator to allow free flow in and control the flow out. FEATURE Through port line body construction for ready installation into hydraulic lines. Fast resposne, high flow capacity. Cartridge pilot section for easy maintenance.

3 PUL PUL PRIORITY UNLOADING VALVE PILOT OPERATED - LIDING POOL TYPE OUTLET () DRAIN () PILOT (4) 4 INLET () APPLICATION These unloader valves are used to divert pump flow to a secondary circuit when pressure in the priority line reaches a pre-set level. The valves will close, causing the circuit to reload, when the pressure drops to approximately 85% of the unload pressure. The most common application is to maintain a pressure in an accumulator which may be used in an emergency to operate an essential hydraulic function (eg, a brake circuit). This valve has a drain port to ensure correct valve function while allowing the bypassed oil to be used for a secondary circuit requirement.

External surfaces zinc plated OPERATION Inlet pressure is seen on the nose of the valve and system pressure (downstream of the system check valve) operates on the system pilot port. When pressure rises to the valve setting, the relief section opens and the system pressure acts on the pilot piston to hold the valve in the open position. The ratio between the pilot piston diameter and the seat diameter of the relief valve pilot section ensures that the valve will be maintained in the fully open position until the system pressure drops to approximately 85% of the unload pressure.

5 UL55 TWO PUMP UNLOADING VALVE UL55 YTEM P T P APPLICATION Two-pump unloader valves are used in systems with combinations of two (or more) pumps to give high flow at low pressure and high pressure at low flow. The valves bypass the flow from the low pressure pump(s) to tank at a pre-set pressure. This allows pump selection to give, for example, rapid advance and high power compaction with the most economic usage of system components and energy requirements. OPERATION Pump inlet to P and P is combined to give maximum flow at low pressure. When the load pressure increases to the valve setting the high flow (low pressure) pump is bypassed from P to tank allowing nearly all system power to be used for the high pressure pump. (ee graph for the pressure drop of the dumped flow). The system relief valve provides protection by limiting the maximum pressure in the system line. FEATURE This is a self contained system including two replaceable cartridges with full adjustment through their respective ranges. Hardened working components give long, trouble-free life and single body reduces plumbing to a minimum.

7 CETOP OVERCENTRE TACKING LICE PILOT AITED RELIEF WITH CHECK *CE/ *CER/ *CEB 4 APPLICATION Overcentre valves give static and dynamic control of loads by regulating the flow into and out of hydraulic actuators. When installed close to or within an actuator, the overcentre valve will stop runaway in the event of hose burst and if open centre directional control valves are used, will allow thermal expansion relief of the hydraulic fluid. ingle overcentre valves are normally used when the load is unidirectional, for example an aerial platform or crane and dual overcentre valves are used for controlling loads in both directions for motor applications or for cylinders going over centre. The CER series overcentre valve performs all duties of a regular overcentre but is able to relieve and stay open irrespective of downstream pressure. This enables the valve to operate when used with a closed centre directional valve which has service line reliefs. The poppet is pressure balanced, preventing relief setting increase due to back pressure.-- In the CEB series pressure balanced overcentre relief setting is unaffected by back pressure, enabling the valve to stay open when the valve port pressure rises. This will allow the control of regenerative or meter out proportional systems. OPERATION The check section allows free flow into the actuator then holds and locks the load against movement. The pilot assisted relief valve section will give controlled movement when pliot pressure is applied. The relief section is normally set to open at a pressure at least. times the maximum load induced pressure but the pressure required to open the valve and allow movement depends on the pilot ratio of the valve. For optimisation of load control and energy usage, a choice of pilot ratios is available. The pressure required to open the valve and start actuator movement can be calculated as follows: Pilot Pressure = (Relief etting) - (Load Pressure) Pilot Ratio FEATURE Integrated Hydraulics Ltd ATMOPHERIC VENT *CE *CER *CEB Cartridge is economical and fits simple cavity. Allows quick, easy field service - reduces down time.

Ideal for use in two pressure systems or to protect low pressure actuators such as brake cylinders. Note: where reverse flow is required, see PAA95, page number 5-6. OPERATION This valve is normally open, allowing oil from the inlet to pass through to the regulated port of the cartridge. When the regulated pressure reaches the valve setting, the pilot section opens causing a pressure imbalance across the main spool which moves, throttling the inlet flow, preventing any further pressure rise in the regulated line.

24 CE ERIE OVERCENTRE VALVE PILOT AITED RELIEF WITH CHECK CE VALVE () PILOT () CYL () 6 APPLICATION Overcentre valves give static and dynamic control of loads by regulating the flow into and out of hydraulic actuators. When installed close to or within an actuator, the overcentre valve will stop runaway in the event of hose burst and if open centre directional control valves are used, will allow thermal expansion relief of the hydraulic fluid. The overcentre cartridge is ideal for mounting directly into a cavity machined in the body of the cylinder, motor or rotary actuator. The cartridge can also be mounted directly to the ports via a specifically machined body as part of a Hydraulic Integrated Circuit or single unit, or contained within one of our standard line bodies. ingle overcentre valves are normally used when the load is unidirectional, for example an aerial platform or crane and dual overcentre valves are used for controlling loads in both directions for motor applications or for cylinders going over centre. OPERATION The check section allows free flow into the actuator then holds and locks the load against movement. The pilot assisted relief valve section will give controlled movement when pilot pressure is applied. The relief section is normally set to open at a pressure at least. times the maximum load induced pressure but the pressure required to open the valve and allow movement depends on the pilot ratio of the valve. For optimisation of load control and energy usage, a choice of pilot ratios is available. The pressure required to open the valve and start actuator movement can be calculated as follows: Pilot Pressure = (Relief etting) - (Load Pressure) Pilot Ratio FEATURE Allows quick, easy field service - reduces down time. mooth, sure performance.
