VG8300N & H Series PN 16 & PN 25, DN 40 - DN 150
Balanced Pressure Nodular Iron Flanged Valves
Introduction
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 through specific
balancing of pressures allows higher close-
off pressures with standard actuator
combinations.
The VG8300N and VG8300H valves can be
used with a variety of Johnson Controls
pneumatic and electric actuators.
VG8300N and VG8300H Valves
(With VA1000 Actuator)
Features and Benefits
Balanced pressure valve. Cost saving technology, expensive high thrust
actuators no longer necessary.

2 VG8300N & H
Application Overview
Valve bodies are made of nodular cast iron and
are available in sizes from 40 mm to 150 mm.
Flanged connections comply with EN and DIN
standards. These valves also comply with
Pressure Equipment Directives (PED).
Information regarding the CE mark can be found
on the valve ID plate. The valve trim and seat
edge are made of stainless steel. The valve
packing consists of spring loaded Viton-Teflon V-
rings.
The VG8300N & H Bonnet
The valve design incorporates a pressure
equalisation chamber above the valve plug. A
connection between the chamber and the area
beneath the plug allows fluid pressures on both
sides of the plug to find a balance. This means
that with higher close-off pressures, the actuator
required to close the valve need not be of as high
a thrust as would be necessary for a normal valve
under similar conditions.
The VG8300N and VG8300H valve series are
available in two-way PDTC configuration.
These two-way valves have an equal percentage
flow characteristic. An arrow is embossed on one
side of the valve body indicating the direction of
flow for correct installation.
The upper operating fluid temperature range limit
of the VG8300N is 180°C and 200°C for the
VG8300H.
Models where packing includes an optional cup
for glycerine anti-freeze are available for fluid
temperatures as low as -10°C for the VG8300N
and -20 °C for the VG8300H.
Note: This option is imperative where
temperatures can fall below 0°C
A variety of electric actuators are available and
can be ordered as a factory fitted valve/actuator
combination or as a single item for on site
installation.

Electric Actuator Selection
Non Spring Return Actuators
VA7810 Electric Actuators
The VA7810 non-spring return actuator with
1000N thrust for valves in heating, ventilation and
air conditioning applications is available for
floating (3-point) control or proportional control.
All models have manual override as standard.
Proportional models are self-calibrating. The
actuator is intended for use with Johnson Controls
VG8300N & H flanged valves.
It provides 1000 N nominal stem force and can be
used with DN 40 valves in accordance with the
max. close-off pressure ratings specified.

valve-actuators are self-adjusting and therefore
have a greatly reduced installation and
commissioning time. They are of modular con-
struction so that for instance, the required type of
control signal is achieved simply by fitting a
module with the required function in-situ.
This actuator can be used with DN40… DN150 at
the specified close-off pressure ratings.

Spring Return Actuators
FA-2000 Electric Spring Return Actuators
The FA-2000 series synchronous motor-driven
S.R. actuators are available for 3-point (floating)
or with electronic positioner for
0…10 V / 0(4)…20 mA control. It provides a fully
variable aperture, a power failure spring return
safety mechanism and an electrical manual-
override (two spring-loaded push buttons).
On power failure, the actuator returns to normal
position.
For example on power failure:
•The FA-2200, FA-2300 and FA-2400 models
extend the stem, thus, when mounted on a
two-way PDTC valve, normal position closes
the valve.
•The FA-2500, FA-2600 and FA-2700 models
retract the stem, thus, when mounted on a
two-way PDTC valve, normal position opens
the valve.
Factory fitted auxiliary switches and 2kΩ-
feedback potentiometer are order options.
This actuator series can be used in conjunction
with DN 40...DN 150 VG8300N & VG8300H valve
bodies.

Installation and Servicing
When mounting the VG8300N and VG8300H
series valves please follow the instructions below:
•It is recommended that the valves be mounted
at angles not greater than 90° from the upright
position, in a conveniently accessible location.
•Do not cover the actuator with insulating
material.
•Sufficient clearance must be allowed for
actuator removal (please refer to the
dimension drawings).
•Install the valve as indicated by the arrow(s) on
the valve body so that the plug seats against
the flow.
•Johnson Controls must approve use of the
VG8300N and VG8300H series valves with
fluids other than specified.
•On electrically actuated valve assemblies, all
wiring must be in accordance with applicable
electrical codes and ordinances.
•Input lines to the actuator must be wired
correctly to open or close the valve as is
functionally required.
