Low Pumping Volume

Because the internal capacity of the valve holds
20μℓ or less, its “pumping volume”（i.e. theexcess fluid displaced by the diaphragm whenthe valve closes）is significantly less than thatof other valves.

Barbed Tube Fitting

Designed to be able to withstand －75 〜 250 kPa,so tubing will not be detached under high−pressure loads.（Compatible with tubes of diameter
φ2 mm）INSTA LLA T I ON VA RI ATION S67（mm）

At startup: 3 W
Regular operation: 1 W

34No Screws Required for Assembly
Can be attached and detached to and from a
DIN rail with one touch. Also incorporates aframe ground（FG）structure, which cuts down
on noise.

Independent Control
Since the coil is housed in a single unit, andeach unit can be operated individually, you canuse our valves for many possible applications.
