irrigation system Z&w zanchen Series Electric plastic Valve with DC Latching Solenoid, 3″

We specialize in producing irrigation solenoid valve 300PH-DC solenoid valve (3-inch) Product Application Solenoid valve in accordance with the commercial standard design 300PH products, durable, high performance, can meet a variety of system environments. Product Features Model: 300PH Size: 3 inches Maximum working pressure: 1400KPa, Manual internal and external drainage function Flow control for accurate flow regulation, and switching valve Body glass fiber reinforced nylon, high temperature Excellent performance nylon reinforcing rubber diaphragm member Built-in bolts, nuts easy installation Brass flow adjustment lever There are slow-off function to prevent water hammer damage the system. Turn the solenoid can be achieved manually open and close within the drain. Double filter to prevent clogging solenoid coils. Closed solenoid coil, core spring as a whole. Optional AC head Pressure regulator Electric or manual operation Downstream pressure range :35-700KPa or 35-210KPa Pressure difference between the upstream and downstream pressure should be maintained at 70KPa Performance parameters: Flow range :1.14-72m/H ³ Pressure range :70-1400KPa VALVE COIL / ELECTRICAL The valve coil is epoxy encapsulated and is water resistant The valve opens when it receives a 50 millisecond (ms) pulse with normal polarity (“positive” connected to red wire and “negative” connected to black wire). The valve closes when it receives a 50 ms pulse with reverse polarity (“positive” connected to black wire and “negative” connected to red wire). NOTE: The length of the pulse is not critical as long as it is at least 50 ms long. General Coil / Electrical · Design voltage: 9-20Volt DC · Amperage draw: 500mA at 9-volts · Max voltage:9-20v DC · Min. 50 ms pulse opens valve · Min. 50 ms reverse pulse closes
