Comatrol introduces the HLE10-CPC and HLE10-OPO high power logic elements. Responding to the market demand for higher flow and pressure capability in smaller valves, Comatrol designed the HLE10 models with the focus on delivering high performance in cost-effective valve designs with small space claims. These logic elements use a 10-3S cavity, which allows for higher flow than a standard 10-3 cavity, and were designed for high pressure of 350 bar (5075 psi).
The HLE10-CPC is high-pressure logic element, normally closed, pilot to close and features a rated flow of 80 LPM (21.1 US gal/min). This valve can be applied as a load-sensing bypass compensator for a fixed displacement pump with single or multiple actuators. Designers can also apply this logic element as a bypass-type pressure-compensated flow control.
The HLE10-OPO is high-pressure logic element, normally open, pilot to open and offers a flow rating of 60 LPM (15.8 US gal/min). This logic element can be used as a pre-compensator for proportional directional control or flow controls. This valve is the perfect fit when used in combination with Comatrol’s new PSV-12-34 proportional directional control valve for compensated flow control. Use of this logic element as a compensator ensures that flow rate, and subsequent actuator speed are maintained regardless of the load pressure.
The addition of these 10-3S cavity valves allows Comatrol to offer circuit designers a full range of sizes for these two popular schematics – 10-3, 10-3S, 12-3S, 16-3S and 20-3S size options. The family of valves provides flows ranging from 50 LPM (13 GPM) to 320 LPM (85 GPM) for the CPC schematic and from 40 LPM (11 GPM) to 200 LPM (53 GPM) for the OPO schematic – at 7 bar (100 psi) pressure drop. With the flexibility Comatrol’s logic elements offer, the range of possibilities is only limited by the designer’s imagination.
