Nugget 500 Series Valves
Design Features Provide High Reliability.
Norgren Nugget 500 Valves feature a precision spool with integral
bonded seals. This design provides superior performance, fast and
easy maintenance, dependable operation, and long life. Other key
features and benefits include:
Two-Year Unconditional Warranty
All Nugget valves are warranted to be free from defects for a full two
years from the date of purchase. This extended warranty period
provides users with a valuable guarantee of quality and
serviceability.
Two Valve Configurations
Nugget 500 are available in a 5-Port/2-Position or 5-Port/3-Position
configuration.
A Wide Range of Valve Accessories
Norgren offers a number of accessories for use with the Nugget 500
Valve, including valve body cover plates, speed control kits, mufflers,
intermediate supply/exhaust block, solenoid exhaust filters, manifold
blanking plates, and isolating plugs. These accessories allow cost-
effective customizing for your specific application.
Small Subbase Footprint
All subbase valves mount on approximately 1.50" ( 38 mm) centers,
reducing installation space requirements.
High Flow
A Cv of 5.0 provides exceptionally high flow for the compact size of
the valve, making the Nugget 500 appropriate for machine control
and general purpose industrial applications.
Nitrile Rubber-Based Seals
All Norgren Nugget 500 Valves utilize nitrile O-rings and seals for
superior compatibility, wear, and operation over a wide temperature
range.
Port and Operator Identification
Each of the ports is identified by a permanent number adjacent to
the port on the body or subbase. In addition, a two-digit number at
each end of the valve body indicates the ports connected when the
operator at that end is actuated. Port and operator identification on
Nugget 500 Valves comply with ANSI and NFPA T3.21.15-1989. See
Operating Variations on page VAL-9-5 for examples.
Durable Finish
External valve body, operator and subbase
surfaces are protected with an oven cured,
epoxy resin paint that provides excellent
corrosion and chip-resistant protection.
Quality Appearance
Norgren's high luster black gives any control
circuit installation a quality appearance reflecting
the superior operating capability built into every
Nugget 500 Valve.
Four Mounting Styles
Inline Valves have two sets of mounting holes
running through the valve body. Inline valves may
be bolted to a surface or may be supported by
connecting piping.
Fixed Length Manifolds allow the installation of
inline valves on a competitively priced common
manifold. For quick installation, valves are
attached to the manifold with two socket head
cap screws. Valves share common supply and
exhaust galleries in the manifold.
A single Subbase Valve is attached to a Single
Subbase with four socket head cap screws,
providing easy installation. Inlet, exhaust,
external pilot supply and cylinder ports are
located on the sides of the subbase.
Subbase Valves are attached to Manifolding
Subbases with four socket head cap screws.
Subbases are held together with a clamping pin
and set screw combination, which reduces
potential leaks and allows quick assembly of
valve stations. Common inlet and exhaust ports
and common external pilot supply ports are
located in the end plates. Cylinder ports are
located in the ends of the subbases.
Closed Crossover
The design of the Nugget spool ensures that no
air flow occurs between supply port 1 and
exhaust ports 3 & 5, preventing the waste of
compressed air.
