GreEQ.0 Low Flow 16-600 kPaD Insert

FlowCon GreEQ insert

The latest contribution to FlowCon International’s comprehensive range of inserts is now available with the introduction of the world’s first full stroke equal percentage characterised insert, named the FlowCon GreEQ insert.

More and more PICV specifications are calling for equal-percentage control characteristics of the control seat and pre-setting, without stroke limitation.

Full stroke equal percentage seat control is new and opposed to linear seat control, which is the standard in typical PICVs, including the FlowCon Green insert range.

Equal percentage control characteristics in PICVs have previously been achievable only through compensated actuator movement or stroke limitation, and, in some instances, both.

Global engineering consulting firm Arup acknowledged the above limitation on existing PICVs, but they refused to accept either stroke limitation or actuator compensation, which led Arup, Jones Engineering and FlowCon International to team up and create an insert capable of and without compromise fulfilling the outlined project requirements, resulting in the new FlowCon GreEQ insert.

Given its equal-percentage characteristic, the FlowCon GreEQ insert is the perfect partner for applications requiring accurate control at very low flow rates.
The GreEQ insert is specially designed for low flow rates, focusing on slow seat opening.
The GreEQ has a minimum setting of 17.3 l/hr (0.0763 GPM) but, due to the slow seat opening, can easily maintain constant flow rates down to 2 l/hr (0.0088 GPM) when modulated by the FlowCon FNQ actuator.
In Fact, the seat opening is limited by the actuator resolution, which defines the minimum flow rate, not by the seat.

The FlowCon GreEQ range naturally fits in the standard FlowCon valve housings, and its launch is supported by its own dedicated actuator range, FlowCon FNQ, available with analogue control, including feedback and optional capacitor failsafe function.
