Control Valve Bodies
These ANSI 250 valve bodies (400# @ 1500F, 250# @ 2500F) are 3-way
diverting 4 port globe valves with built-in tee (piped as mixing valve it can be
used for 5 psi maximum differential pressure.) They are common to all
Spartan actuators and are available in a wide range of Cv (Kv) sizes.
The V420 is a 1/2" compression nut or 15 mm comisa fitting valve body.
Unions supplied extra.
Designed for use on hot or chilled water and up to 50% glycol mix, the
commercial application valve bodies utilize low zinc antidezincification
bronze, coupled with long life replaceable and interchangeable internals
1.0, 2.0, 3.0, 3.5 Cv (0.86, 1.70, 2.60, 3.00 KV’s).
A valve cap supplied with the valve body can be used with limited life as a
manual adjuster when the actuator is removed from the valve body.
Alternatively a more permanent manual adjuster type OM1000 can be use
permanently for longer life expectancy.
All valve bodies have spring-loaded stems, being actuated power driven stem
down to open or close as required by the valve assembly configuration.
All valve bodies have replaceable and / or interchangeable internals to enable
Cv (Kv) size change or configuration change on-site, resizing or servicing
without removing the valve from the line. In all cases, the internals are
complete with world-class specifications including 11/2 - million cycles
(3,000,000-stroke) packing and burnished mirror finished stainless-steel stems.
These control valve assemblies can be used with the complete line of
Spartan Zone Actuators (Electric, Electronic, Pneumatic & Thermostatic)
and are easily interchangeable with a thumb-nut.
