2021-7-1 · Constant Flow Valve Principle Constant Flow Valve keep flow rate of gases or liquids at constant value even when the supply or load pressure changes. Control valve with diaphragm automatically acts following the change of pressure. They are normally delivered together with flowmeter as a "Purge set".
CONSTANT FLOW CONTROL VALVES. and have expanded flow ranges from 0.25 to 30 GPM. Flo-Trol® automatic flow control valves are designed to give constant flow over a wide pressure ranges. The internal controlling mechanism has no moving part consisting only of a flexible orifice that varies with applied pressure maintaining a constant flow rate.
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.
2021-7-20 · Designed to give constant flow over a wide pressure range. The valve is designed in a stainless steel construction and has no moving parts rather a self-cleaning flexible orifice that varies in size with applied pressure so that a constant flow rate is maintained NSF/ANSI 61 Certified.
2021-3-12 · 80-600mm. Rated pressure. 1MPa. 1. An orifice is provided at the inlet side of the valve and differential pressure (P 1 -P 1 ) that arises between the front and the rear of the orifice due to the flow rate fluctuation drives the pilot valve thereby opening and closing the main valve and maintaining the set flow
2021-6-10 · Constant pressure valve range. Alfa Laval offers three types of CPM valves. Modular design enables the use of different plug sizes and different flow rates between 0.5 and 110 m3/h provide great operational flexibility. Upon request some CPM valves can be provided as ATEX-approved valves (group 2 category 3 D G applications) for use in
The FlowCon Wafer Constant Flow Valve range is designed to meet the higher capacity flow limiting requirements in 50mm -1000mm. Applications include air handling units boiler flow control multiple chillers or pump system balancing in high-rise building as well as industrial applications.
