About Electric Valves
1. SAFE AND RELIABLE- Comprised of strong, trustworth brass, this valve is reliably safe; Lifespan of 80,000-100,000 cycles means a valve that will last
2. NPT or BSP THREADING- 1/2" Brass threading, manufactured and measured according to National Pipe Thread standards; This electrical ball valve is standard port, meaning the bore in the ball is a little less than 1”; This minimizes pressure loss through the valve; Perfect for home automation projects
3. 110V-230V AC/DC- Works effectively over entire voltage range; Will open or close valve in 3-5 seconds; Limit switch minimizes power after valve is fully open; Ideal for projects where an automatic return is necessary
4. 2 WIRE AUTOMATIC RETURN SETUP- Simple two wire connection, valve largely de-energizes after opening; Returns to fully closed if power is removed
5. ALTERNATIVE TO SOLENOID VALVES- Automatically cuts off power once fully open or fully closed; This reduces likelihood of overheating, making it a great alternative to solenoid valves for projects where a valve needs to be open for an extended period of time
Motorized ball valves are a great alternative to solenoid valves when the valve needs to remain in position for an extended period of time. Solenoid valves will get hot, as they are constantly energized. Motorized ball valves are an enticing, energy efficient alternative. The valves consume energy during the actual opening and closing process, and only negligible amounts once fully opened, meaning it can be permanently connected without risk of overheating or burning out. Auto return valves, in particular, are a perfect fit for those looking for emergency backup systems. When power is removed, the valve automatically closes, which can be great in times of trouble. These valves are not intended for situations where fast action closing or opening is needed, as they do take a few seconds to fully open and close.
