DV-5 Diaphragm type deluge valve and deluge system DN40 ~ DN200 1.72 Mpa external reset Qinghai fm certified fire valves, vertical or horizontal mounting deluge valve with external reset function, without opening the valve hand hole fm certification Fire cocks Price, Simple pressure on the diaphragm chamber, you can reset the deluge systems or pre-action system. In addition to the membrane structure, the valve is not connected to the valve and rotating parts. The valve / external anti-corrosion coatings. When the valve is used to authenticate the fire deluge system Hunan fm valve, 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. PS40A series of pressure switches for detecting or drop 10psi (0.69bar) ??of pressure change increases the pressure setpoint 10psi (0.69bar). Typical applications are in the pipeline pressure monitoring system in a dry system, or monitoring compressed air tanks, air and water pressure, PS40-1A containing a pair of SPDT contacts, the pressure drop operation; PS40-2A containing two pairs of SPDT contacts, an increase in the pressure setpoint 10psi (0.69bar) ??or drop 10psi (0.69bar) ??occurred. Pressure adjustment range 10-175psi (0.7bar-12bar), the pressure switch must be installed vertically.
