Assembly of a typical remote electrically modulated relief valve is shown in Figure 1. In general, the valve consists of three basic parts, a main stage, an intermediate body and the electrically modulated pilot. The main stage is similar to the stand relief valve. The intermediate body contains standard relief valve pilot parts to provide manual adjustment and has a mounting pad which accepts CETOP 3 components. The electrically modulated pilot is machined to fit the CETOP 3pad and contains a flapper valve assembly, a blocking valve, and a ball type check valve.
Product Description
The new valve series provides a self-contained unit that modulates system pressure electrically over a wide range without external feedback devices.
The valve has the ability to control system pressure from any distance or location. Modulating signals may be derived from potentiometers, analog computers, power supplies or any other source that will provide the necessary drive current for the pilot stage. A current of 0-500 milliamperes (mA) is required to modulate the valve.
Power supply EMCS-*-30 was specifically designed for control of this type valve. The EMCS is not limited to potentiometer command only but can easily be adapted to remote control devices. For information on EMCS, refer to installation drawing 521557, from Technical Publications, Troy, MI 48084.
