DPV1 Proportional Valve Proportional solenoid valves allow the flow rate of fluid passing through the valve to be adjusted anywhere between fully off to fully open. To accomplish this, the power to the solenoid coil is adjusted to open the valve more or less. Devices such as flowmeters, thermistors, or pressure sensors are commonly used to provide the feedback necessary to determine the power input to the solenoid coil to achieve the desired output. Features. Adjustable flow rates between 0% and 100%. Up to 1.7... (read more)Browse Solenoid Valves Datasheets for Deltrol Controls/Division of Deltrol Corp.

Also, if the press’s motor is not producing sufficient RPMs, a drop in pressure could occur. Users should be tuned into various processes on their hydraulic presses to ensure good operations. For example, the valve shifts should be smooth from one speed change to the next - operators should not hear...
