DV-5 with a single interlock preaction pressure monitoring system (power-up or a wet or dry start to start) DN40 ~ DN200 preaction valve from the DV-5 Deluge valve and lift check valve composed of the check valve airtight when closed, so that the valve does not require pre-injection. When using electric start pre-action system, motion detection system after power is turned preaction valve diaphragm chamber drain valve solenoid valve Chengdu signal, the pre-action valve is open. DV-5 Diaphragm type deluge valve and deluge system DN40 ~ DN200 1.72 Mpa Anhui external reset signal valve, mounted vertically or horizontally DV-5 Deluge Valves are diaphragm type structure, valve size DN40-DN200, vertically or horizontally. Automatic control valve used to supply water systems and other fire protection systems - in the deluge system, pre-action system, foam. Matching the appropriate valve piping components in the system operation, the deluge valve to provide a fire alarm signal. Deluge valve with external reset function, without opening the valve hand hole, simply for the diaphragm chamber pressure, you can reset the deluge systems or pre-action system. In addition to the diaphragm structure Shenyang signal valve, the valve is not connected to the valve and rotating parts. The valve / external anti-corrosion coatings. When the valve is used for the deluge system, internal anti-corrosion coating can be resistant to seawater and salt corrosion. External anti-corrosion coating so that the valve can be used in a corrosive environment, industrial and outdoor installation.
