Then valve element B y connected to the valve element A t is open. When the pilot operated solenoid valve !2 is energized, the pilot air supplied to the bottom of the piston u moves upward to open the valve element A t and closes the valve element B y. Because rod !0 is connected to valve element A t by parallel pin !1.

The HRW series thermo-chiller is a high-performance device for circulating a fluid at a constant temperature (Water-cooled type).  Energy saving is substantially increased by exchanging cooling water and heat directly.  The HRW can achieve reduction in power consumption as it does not have a compressor, and reduction in the amount of facility water used because heat is exchanged directly
