This family of potable water components (valves, regulators, fittings, tubing and hoses) includes potable water solenoid valves. These NS-Series NSF (National Sanitation Foundation) certified valves (from GC Valves) are an excellent choice for food and beverage grade potable water applications. Stainless steel or thermoplastic bodies and synthetic seating and sealing materials makes NS series valves suitable for use with a variety of liquids, oils and gases. Valve operation is 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; NS201 series valves can also operate under zero pressure differential. NS201 and NS211 series valves have 316L stainless steel or Nylon 6 bodies and are ported for 3/8, 1/2, 3/4, 1, 1-1/4, 1-1/2 or 2-inch NPT. These valves are available with 120VAC, 24VAC or 24VDC solenoids. 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 pressu...
