"Plumbing System for Comfortable, Enriched Life" Mikuni develops functional devices that control water flow installed in residential plumbing systems serving bathrooms, kitchens, washstands, etc.

Water Control Devices

Small Solenoid Valves

Control gateway of water passages.
Compact and lightweight suited for small spaces.
Low power consumption design makes possible use of PWM control to hold valve open.
Flow control by valve itself allows flexible design for its location (such as at inlet or outlet or in passageway).

Small Solenoid Valves

(Specification)

Item Description
Rated voltage 12V DC (100V AC can also be used with full wave rectification), valve open at ON
Rated power consumption 3.2W for continuous conduction, 0.8 for PWM control
Operating ambient temp. -20 to 60℃
Operating fluid tap water
Operating fluid temp. 0 to 80℃(no freezing)
Operating pressure 0.02 to 1MPa
Pilot Solenoid Valves

Control gateway of water passages.
Suited for use in small spaces because smaller and more lightweight than direct operated type.
Low power consumption design makes possible use of PWM control to hold valve open.
Gateway connecting method allows body design to meet required flow.

Normal Open Water Valves

Perform gateway control of water passageway.
Can be used to open valve at abnormal and emergency condition (when power goes out).

Normally Open Valves

(Specification)

Item Description
Rated voltage 100V AC full wave rectification, valve closed at ON
