DV-5 Diaphragm type deluge valve and deluge system DN40 ~ DN200 1.72 Mpa external reset, good fm certified fire valves, vertical or horizontal mounting DV-5 Deluge Valves are diaphragm type structure, valve size DN40- DN200, can be mounted 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. ACC-1 dry-type valve Accelerator has a unique, built-in direct action anti-overflow device and float through a combination of both, Qinghai fm certified fire valves, blocking water and debris from entering the accelerator sensitive operating area. Sealing and locking anti-flooding devices depends directly on the ACC-1 Accelerator own motion, after the middle of the dry valve chamber without waiting to accumulate a certain pressure. Performance gear locking pin to make anti-overflow device at the drainage system can remain sealed. When the dry valve malfunction, such as compressor failure and when the system air pressure due to leakage and gradually decreased, professional certification fm fire valve, the float will seal the control chamber entrance.
