Employing the latest pulse width modulated solenoid electronics, these valves minimize solenoid holding current while providing a much wider input voltage range. The direct solenoid design is ideal for use in vacuum, low pressure or high pressure applications where pilot-assisted valves won’t operate.
Low maintenance and high reliability are hallmarks of the Bronze Star™ valves due to the elimination of any small orifices that can clog during operation. In addition, pulse width modulation electronic technology permits a very low solenoid holding current. This minimizes heat and power consumption, resulting in reduced operating costs and virtually trouble-free operation for millions of cycles.
