AutomationDirect NSF-certified valve line designed to handle potable water.
AutomationDirect has added solenoid valves to its family of potable water components. The company’s NS-Series NSF (National Sanitation Foundation) certified valves are normally closed (N.C.) and open when electrically energized. The valves can be mounted in any position and a spring-loaded plunger assures positive shutoff. Three types of 2-port (2-way), 2-position NS series valves are available. NS201 and NS211 series are piloted diaphragm valves with 316L stainless steel or Noryl bodies and are ported for 3/8, 1/2 or 3/4 inch NPT. NS301 series valves are direct acting with an armature that acts directly on the valve orifice to control fluid flow and does not require a minimum pressure to operate. These valves have 303 stainless steel bodies and 1/4 inch NPT ports.
