3 S o l e n o i V a l v e Selection of What is a?? A solenoi valve opens/closes by moving a piece of steel calleplungerby magnetic force of solenoi, an is applie to the flow control (on-off control) in the piping for fluis. The solenoi valve opens/closes more quickly than a motor valve. Applications Water supply an rainage for general househols Plant facilities Inustrial machine Air-conitioning facilities Builing facilities Plant facilities Air-conitioning facilities Builing facilities Plant facilities Direct acting type Pilot operate type Directly opens/closes the valve isc by attraction effect of electromagnet. Opens/closes the valve isc by opening/closing its pilot valve by attraction effect of electromagnet. Piston type Diaphragm type Types DD-1 Series DP-10 Series DP-12 Series Major Proucts Piston works as the main valve. Diaphragm works as the main valve. Features wie application for fluis such as air, water, oil, steam, etc. an reliable operation by simple structure. The DP-10 Series meets the emans for high reliability of automatic control evices as the automation of process grows in various inustrial fiels.

When use at less than MPa pressure, the valve shoul be installe horizontally with the coil up. The vertical installation is limite to the conition that the ifferential pressure between the inlet an outlet sies is MPa or more. Warning an caution for installation 1. Before connecting the prouct to piping, remove foreign substances an scales insie the piping. Note that the seal material must not flow into the insie of the prouct. 2. When installation, check the irection of the prouct so that the flui flowing an the arrow marke on the prouct are in the same irection. 3. As shown in the above figure, it is recommene that stop valves, strainers, pressure gauges an bypass line be installe to the piping. For screwe valve, a union joint is recommene to install for easy maintenance an inspection. 4. Make sure to install a strainer with the mesh size -100 at the inlet sie of the prouct. 5. Avoi over-tightening of screw an excessive stress impose from the piping in orer to prevent malfunction ue to the istortion of the boy. 6. Vertical or horizontal installation is possible, however, the coil must be installe above the horizontal level. 7. Secure a space require for isassembly or removal of the prouct at the time of maintenance an inspection. 8. Solenoi valve an motor valve are not explosion-proof.

29 E m e r g e n c y S h u t o f f S y s t e m MD-71KS-5 What is an Emergency Shutoff System? If a piping system is amage by a big earthquake, important water for living store in a water receiving tank or gravity water tank will be lost. It is, therefore, necessary to prevent the interruption of lifelines an reserve water for living after the isaster. Aitionally, national stanars an guielines stress the necessity ofemergency shutoff valvesfor the purpose of preserving water. Yoshitake's emergency shutoff system comprises anemergency shutoff valvean anemergency shutoff valve control consolean is esigne to automatically close the valve when the earthquake sensor insie the control console works. It is capable of supplying water for living reserve in the water receiving tank or gravity water tank even after a isaster.

One Gal is efine as an acceleration of 1 centimeter per secon (1 cm/s) per secon. That is, the gal can also be expresse as 1 centimeter per secon square (1 cm/s 2 ). In the International System of Units (SI), the unit of acceleration is meter per secon square (m/s 2 ), an 1 Gal is equal to 0.01 m/s 2. Although the gal is a non-si unit, Japan's Measurement aw permits the use of Gal an Milligal (mgal) only for the measurement of gravitational acceleration as well as vibration acceleration regaring earthquakes.

An earthquake sensor (acceleration: Gal) is installe insie the control console that automatically works in case of an earthquake (the shutoff valves close in intensity 5 upper). 2. The control console properly works with the backup power source even in case of a power failure. 3. The pump instantly stops when the shutoff valves close (this requires wiring between the interlock terminal of the emergency shutoff valve control console an that of the pump control console). 4. Resetting after a shutoff is easy just by pressing the shutoff valve opening switch. 5. The control console can be manually operate. Emergency Shutoff System
