VG8300N & H Series PN 16 & PN 25, DN 40 - DN 150
Balanced Pressure Nodular Iron Flanged Valves

ntroduction
The VG8300N PN 16 and VG8300H PN 25
valve series are designed primarily to
regulate the flow of water and steam in
response to the demand of a controller, in
heating, ventilating and air conditioning
systems.
These two-way Push-Down-To-Close,
nodular cast iron valves have a specially
designed plug, which
balancing of pressures allows higher close-
off pressures with
combinations.
The VG8300N and VG8300H valves can be
used with a variety of Johnson Controls
pneumatic and electric actuators.
Balanced pressure valve.
PN 16 & PN 25 rated valves available.
Nodular iron valve bodies.
Stainless steel stem-plug-welded seat area
combination.
Pneumatic and electric actuators available.
Use of standard Johnson Controls spring
loaded, self-adjusting Teflon-Viton-Teflon
V-ring packing.
Low leakage rate.

VG8300N and VG8300H Valves
(With VA1000 Actuator)
Cost saving technology, expensive high thrust
actuators no longer necessary.
Johnson Controls flanged valve program covers a
wide range of applications (body ratings PN 6,
PN 10, PN 16, & PN 25).
Compact, lighter and more ductile than ordinary cast
iron (EN-GJS-400-15-LT: PN 16)
(EN-GJS-400-18-LT: PN 25).
Provides stability and durability.
Allows optimum choice of actuator.
Reliable, field-proven seal applicable to wide
operating temperature range. No readjustment
required.
Provides maximum energy efficiency.
Simple and robust quick-fit coupler system reduces
installation costs.
No silicon particles floating free.
