3/4-Inch Gravity Feed Direct-Acting Electric Solenoid Valve 24VAC 3/4&quot; BPS INLET/OUTLET PORTS It is very important to understand that BPS thread is NOT common in the USA. (The USA standard is NPT threads.) You will need BPS to NPT adapter fittings at both ends. We recommend using 3/4&quot; Transition Union - BSP x NPT Threads, also sold on this page. To prevent leaks, use 6 to 10 turns of Teflon tape on all threads. These Union Coupler type connectors are recommended for easy inspection and cleaning in case valve becomes clogged. STRAINER INCLUDED ... to prevent clogging by large debris. In installations with no large debris, it may be prudent to remove the strainer. WIRE CRIMP CONNECTORS INCLUDED To connect controller wires, we include  female, 22-16 AWG wire crimp connectors. DIRECT ACTING VALVE The solenoid plunger directly opens/closes the orifice inside the valve. Unlike normal irrigation valves which require ~5 psi, these valves can operate with zero pressure. Model:  NicheNOVA&nbsp; B0074AJXAW Voltage: 24 Volt AC (Suitable for use with most types of irrigation timers.) Watts: 7 Operation Mode: Normally Closed. Valve opens when activated &amp; closes with spring pressure. Valve Type: Direct Acting (Gravity Feed) Inlet/Outlet Ports: 3/4&quot; BPS (requires BPS to NPT adaptors.) &nbsp;OD: 1&quot; &nbsp;ID: 0.8&quot; &nbsp;Orifice: 0.4&quot; Pressure Rating: Min pressure: 0 psi; Max pressure: 116 psi Rain Cap: Rain cap included for outdoor usage. The solenoid valve is not submersible. Suitable Media: Water &amp; low viscosity fluids compatible with silicone, nylon and stainless steel. Temperature Limits: Max. Temperature 195F (90C). Min. Temperature 33F (0.5C). Liquid must remain fluid &amp; NOT freeze. Response Time: Fast Acting Materials: Nylon Body; Stainless Steel Spring and Plunger; Silicon Rubber Plunger Tip Estimated Life: More than 250,000 Cycles
