- Page 2 Introduction The following instructions are to provide information on the Installation, operation and maintenance of ECO Valve, diaphragm style valves, manufactured by Primary Fluid Systems Inc. The valves are designed to help improve the performance and safe operation of most positive displacement pumps.
- Page 3 Back Pressure /Pressure Sustaining Valve: Reason for Selection and Use Metering pumps having an atmospheric discharge system pressure or less than 20 psi will benefit from the installation of a back pressure control valve. Metering pumps in general require downstream back pressure to ensure smoother function of the discharge check assemblies, which enhances the accuracy of the discharge flow.
- Page 4 The valve is supplied from the factory pre-set at 50 psig. To increase the pressure setting, back off the lock nut located beneath the colour coded bonnet cap. Turn the Allan bolt using a 5/16” or #8 hex key clockwise to increase pressure setting or counter clockwise to reduce pressure setting.
- Page 5 Manual Air Release The valve is shipped with a factory set pressure of 50 psig. The diagram to the left shows a cut away view of the position of the diaphragm on the seat. To adjust the valve to relieve air or gas downstream: 1.
