Akro water saving valves maintain a fixed constant flow rate and are used in many hotels and homes to save water and money. They are fitted with the high performance Maric flow control rubber.. As the UK Government and building standards recommends 6 Litres per Minute for hand washing and 9 Litres per Minute for showers these valves are a perfect retro-fit to washbasins kitchen taps
1991-12-5 · Pressure differential across the valve moves the cup member against a resilient spring to expose that side port area appropriate for a constant flow rate at that pressure differential. There is always a minimum pressure differential required to establish the desired flow rate for the Golestaneh and other prior art control valves.
2021-7-22 · In short pressure compensated flow control valve will provide the constant flow to the actuator by changing the size of orifice in proportion with change in the system pressure. In order to provide the constant flow to a hydraulic actuator spring loaded compensator will maintain the constant pressure difference across the valve.
