Teejet 244C Pressure Re-life Valve 12 Volt. The AA244C remote control electric regulation valve has been specifically designed to provide remote pressure control in agricultural applications using DirectoValve AA144A or AA145 solenoid shutoff valves. Features: Unrestricted flow when wide open - 5 PSI (0.34 bar) pressure loss for 28.4 GPM (107 l/min) flow. Bypass flow rate: 2 GPM (7.5 l/min) at 10 PSI (0.7 bar). Operates in 12 VDC system and may be controlled by a double-pull double-throw spring-centered switch. Maximum operating pressure of 100 PSI (7 bar). Two-wire lead for use in 12 VDC system. 3/4 inch (F) NPT or BSPT connections. Easy installation (flows either direction). Good corrosion resistance. Low current draw (0.10 AMP). 20 second response time.
