Magnetically Latching Solenoid Valves for Auto taps, Urine flushers and Cistern flushing systems.
All G series valves manufactured by us are
being used as control valve in automatic water faucets,
urinal flushing system, auto taps and sensor taps. They
are used in electrical versions of such devices. Where
mains supply is used as power source.
Battery operated
sensor taps are convinient to install, lower on
maintenance, does not require any plumbing or electric
wiring at the location, hence it is ideal for new as well
as locations where conventional taps are to be replaced.
Since, electrical water valves require continous source
of power, it is not possible to make taps which operates
of low cost, low powered battery like 6 V lithium camara
battery or alkaline batteries.
General Imsubs offers wide range of water valves which
has magnetically latching operators, which requires maximum
60 mS pulse for latching and delatching. Hence offers very
long battery life.

* Timing shown here are based on actual voltage and pulse width. Wave form of pulse width, voltage drop across the switch determines pulse width. Hence it is recommended to adjust pulse width and voltage to valves suitably.
How magnetically latching solenoid valve works
Magnetically latching solenoid valves employs magnets and electrical current to effect operations at expense of very little electrical power.
When electrical current is applied to coil, based on polarity of magnet and direction of current flow valve is latched or delatched.
When current polarity is reversed, valve latches if in delatched position and vice versa.
