Our Constant Flow Valve is a pre set flow controllers which is simple to fit and ensures constant pre set flow rates. Available with screwed connection, in brass, PVC and stainless steel with NBR control ring. Operating from - 25ºC up to 100ºC, minimal pressure 1.4 bar. Sizes 1/2" to 2".
Flow control valves are for clean liquid applications and provide a flow of liquid at a pre-determined level against a variation of pressure within the system, independent of line pressure changes.
The valve operates by means of a rubber orifice (control ring) housed in a pre-formed tapered housing, that reduces in size as the pressure increases. As the pressure reduces the control ring returns to its original shape thus balancing the flow.
Installation is possible on pipe work in any plane.
VOLT flow controllers can be used to: control backwash flow rate to prevent loss of media in media filters, control of service water flow through delicate filters, control trickle flow of sampling water to analysing instrumentation, chemical dosing flow rate control and to limit peak flow rate through ultraviolet sterilisers to ensure 100% bacteria kill.
