Manufacturer: Fushiman Co.,LTD.
Model: P100-3Y

Model	Nominal Diameter	Primary Pressure	Secondary Side Setting Range	Maximum Operating Temperature	Body Material	Connection
P100-3Y	15〜150	MAX. 1.6MPa	0.03～1.0MPa	90℃	CAC	Threaded, Flange

Certified by the Japan Waterworks Association Certification Center (Items listed in bold blue font)

Since it is a low-noise type, there is no concern about water flow noise.
The connection parts are made of CAC and SUS, so no special consideration for piping is required.
The strainer is housed inside (nominal diameter 15-100), so a strainer on the inlet side is not required.
The installation posture can be either horizontal or vertical piping.
As it is a balanced structure, it is hardly affected by variations in the secondary side pressure.
Since the body uses synthetic rubber, the valve closure is good.
The valve box inlet has a pressure measurement tap hole for connection to the piping (for nominal diameters 15–25).

Noise Characteristics

With a primary side pressure of 0.6 MPa and a set pressure of 0.2 MPa, the actual measured value for a sound level of 30 dB(A) at a distance of 15 cm is shown.
The noise value at pressures other than 0.6 MPa (primary side) and 0.2 MPa (set pressure) will differ from this graph.
