Description

AVC check valve is designed for being used with the Iwaki HRP Metering Pump and works for both back-flow check and bleeding.

• Set Pressure: 0.1 +/- 0.03 MPa*
• Function change between checking and bleeding: Checking or bleeding can be selected by rotating the air vent valve (knob) 270°.  The rotation limit is determined by stoppers **.
• Checking: Rotate the air vent valve clockwise as far as it will go.
• Bleeding: Rotate the air vent valve counter clockwise as far as it will go (limited by a stopper).
• Applicable pump: HRP

The HRP series is a diaphragm metering pump which consists of a pump head, drive unit and control unit. A diaphragm is directly driven by electromagnetic force.  The use of a check valve prevents a back flow, siphon and overfeeding. In the following cases install a check valve to assure back pressure and a constant flow rate.
