Eaton Corporation has introduced a high-flow proportional pressure relief valve with integrated control electronics. This plug-and-play unit has an industry-standard seven-pin connector hook-up. The new valve, designated KBCG5-3, complements Eaton's KB proportional valve series by extending the flow capability up 40 litres per minute while offering all the same features and functions of the range.Colin Cooper, product manager of industrial controls for the EMEA region, said: 'This new valve is designed to help extend the flow rate options within our KB series and thereby broaden the scope of potential applications. 'It has all the features offered by the other units in the range plus an onboard pre-programmed amplifier to ensure the maximum consistency of functionality,' he added.
Features offered by the new KBCG5-3 valve and common to all units in the KB range as standard include: onboard digital electronics with ramp adjustment; IP65/67 environmental protection; a choice of voltage and current command supply; five different pressure settings; hysteresis and linearity stability; and electrical power-down 'failsafe' protection.
In addition to these features, the KBCG5-3's integral amplifier is pre-programmed with preset pressure ratings to help ensure consistent pressure gain settings and valve-to-valve performance repeatability. Options include voltage or current command supply and an external valve-enable function.
