The No-Feed Detector is an optional part.

The valve arm and the valve disk form the counterweight.

Installation positions of the by-pass valve and the No-Feed Detector are on the right side when viewed from the inlet side.

May be used in vertical piping, but please pay attention to installation, maintenance and inspection.

The coil sleeve can be attached as an option.

Flange dimensions are based on JIS 10K or waterworks standard (equivalent to JIS B2062).

Applicable liquid temperature : 0-70 degree C
Please contact us if liquid temperature is more than 70 degree C.

Please contact us if flange standard is higher than JIS 16K.
