The Model 5311 consists of an integrated solenoid valve with adjustable pressure regulator and control module, both of which operate from 12 VDC. A 90-240 VAC universal power module provides the necessary power. As an option, the Controller can be battery powered. Battery size required is determined by how long the system must operate. The solenoid requires approximately 250 ma when turned on and the controller only 10 ma when the solenoid is off. The Controller comes standard with a ¼" NPT fitting. This may be screwed directly into the chamber wall or passed through a compression fitting. Optional mounting configurations are available.
