Features and Benefits
The 48 Series comes standard with a 10-point terminal strip, which accommodates an external solenoid valve and is fitted with two (2) ½” NPT conduit entries (M20x1.5 upon request). This feature eliminates costly junction boxes and associated labor.
High visibility indicator offers clear location of the current valve position. Alternative 3-way (L-Port and T-Port) indicators as well as throttle Arrow indicators for butterfly valves applications are also available.
Switch boxes come standard with stainless steel captive cover bolts.
NAMUR 80mm x 30mm x H30mm stainless steel bracket supplied as standard with stainless steel fastening hardware for ease in mounting the switch box onto an actuator. Available upon request, a universal stainless steel mounting bracket suitable for NAMUR 80mm x 30mm x H20mm and 80mm x 130mm x H50mm.
CSA Approved for Classes 3211 06 and 3211 86 for Industrial Controls Equipment. Testing conducted according to the applicable sections of CAN/CSA C22/2. ANSI/UL 508 and ANSI/UL 50.
