1. This is an economical "JAR TOP" solenoid valve with "Dia. 25mm. (1-inch) 'NPT' Female Pipe Threaded Inlet & Outlet", which is designed primarily for residential and light commercial irrigation, that features solid construction / convenient operation & reliable performance.
2. This series of "JAR TOP" solenoid valves have 2 options:
WITH "Manual Internal Bleed Handle" (Our Model No. "DSF-1M-FF"), or WITHOUT "Manual Internal Bleed Handle" (Our Model No. "DSF-1-FF").
3. Each type both having an "External Bleed Plastic Screw", they can be matched with our following irrigation solenoids:
"S391" series ("Black Cylindric Plastic Encapsulation" models) and "S392" series ("Black Epoxy Painted Cylindric Metal Shell" models), that are produced by ourselves at different voltage ratings, such like "DC 12V or 24V", "Pulse DC 4-9V or 6-40V Latch", "AC 12V or 24V", also "AC 110V or 220V" etc..
4. Features:
(1) options of WITH or WITHOUT "Manual Internal Bleed Handle", BOTH WITH "External Bleed Plastic Screw";
(2) plastic valve body and bonnet are both made of the "Weather-proof" & "Corrosion-resistant" engineering material: "NYLON / PA 66 (reinforced with 30% glass fibres)" for a longer life duration;
(3) robust synthetic rubber diaphragm ensures the "leak-proof" seal;
(4) special valve configuration with the "self-cleaning" function is "debris-tolerant";
(5) "self-aligning" plastic valve bonnet permits "fast-service" & "easy-maintenance";
(6) "high-flow" & "low-head-loss" design.
