	Flow Controls
	FLOW RESTRICTOR VALVES TO CETOP 3, 5 & 7
	MERS & ERS Flows to 250 l/min   Pressures up to 350bar Duplomatic restrictor type flow controls are manually operated orifices which increase the pressure drop for any given flow rate thereby restricting & reducing the flow. They are ideal for limiting the speed of a system but they will allow different flow rates at different differential pressures. Typical applications are where a small amount of flow control or flow trimming are necessary.       ADVANTAGES VARIABLE RESTRICTIVE FLOW CONTROL Flow restriction by manual adjustment to 'meter out' or 'meter in' on ports A or B. CHECK VALVE FOR REVERSE FREE FLOW Reverse free flow non return valve facility. SUBPLATE MOUNTINGS TO CETOP 3, 5 & 7 Units supplied with mounting flanges to the latest CETOP 3, 5 & 7 standard. Ordering D-MERS D-ERS4M D-ERS07M Description Flow restrictor to CETOP 3. 350 bar & 75 lpm. Define meter in or out. Define P, A or B port control. Flow restrictor to CETOP 5. 320 bar & 100 lpm. Define meter in or out. Define P, A or B port control. Flow restrictor to CETOP 7. 320 bar & 250 lpm. Define meter in or out. Define P, A or B port control. Temperature Oil temperature should be between +30ºC & +60ºC during normal operation. Oil life is greatly reduced if temperature exceeds 60ºC. As a general rule, oil life is halved for each 8ºC temperature exceeds 60ºC. Filtering It is necessary to keep the level of contamination within a hydraulic system at an acceptable level to ensure trouble free operation. Filtration should always be specified at a level that protects the most sensitive item or component in the system.
