Nugget 500 Series Valves
Operator Choices
Solenoid pilot and air pilot operators are available for primary
actuation and return operation. For secondary operation air-assisted
spring return, spring return and integral air return operators are
offered.
Low Wattage Solenoid Operators
AC and DC operators requiring only 3.5 and 2.0 watts of power,
respectively, are ideal for computer based control systems as well as
industrial applications where minimum energy consumption is
desired. Faster response times are realized using the 7.5 watt AC
and DC operators.
Solenoid Exhaust Filter
Optional solenoid exhaust filters, for use in dusty environments, are
available.
Solenoid Diffuser Plug
A diffuser plug installed in the pilot exhaust helps prevent entry of
contaminants during shipping and normal operation. It may be
removed when minimum response times are desired.
Rotatable Connector and Coil
The standard cable grip connector can be rotated 180°, and the
solenoid coil can be turned 360° in 90° increments, making the
operators adaptable for easy installation.
Electrical Connector Options
A cable grip electrical connector with indicator light; a 1/2" NPT
conduit connector and a 5-foot, three-conductor, molded cable
connector with or without indicator light and surge suppression are
available.
Solenoid Manual Overrides
Standard solenoid operators are furnished with manual non-locking
overrides to provide a means of shifting the valve without electrical
power. Optional solenoids without overrides or with locking overrides
are also available.
Internal or External Solenoid Pilot Supply
All inline solenoid operated valves may be
quickly converted from an internal to an external
pilot supply by reversing a one-piece seal
between the operator and the body and
removing the external supply port pipe plug. All
subbase solenoid operated valves may be
quickly converted from an internal pilot to a
common external pilot supply by rotating a one-
piece seal between the valve body and the
subbase to provide pilot pressure from the
external pilot supply port in the single subbase or
endplate.
Sintered Bronze Vent Filters
Internal parts are protected by built-in sintered
bronze vent filters on operators.
High Flow Pilot Exhaust Orifice
An oversized pilot exhaust orifice provides rapid
return time when the valve is deactuated.
