For hydraulics systems with high flow rates, which 03 series valves (Maximum Flow rate of 70 L/min.) are not capable of handling, 06 series modular valves (may flow rates of 500 L/min.) have been conventionally used. In such cases, the use of 04 series valves for hydraulic systems with flow rates up to 300 L/min. will help to reduce both cost and system size. modular valve function yuken india yuken hydraulic valves pdf yuken modular valve pdf yuken directional valve yuken flow control valve yuken valves catalogue pdf yuken make hydraulic valve
