VG8000V Series Flanged Valves
DN 15 - DN 150 •Nodular Iron •PN 16
Introduction
The VG8000V Series electrically and
pneumatically operated nodular iron valves are
designed primarily, to regulate the flow of water in
response to the demand of a controller mainly in
heating, but also in ventilating, and air
conditioning systems. They are available in two-
way configurations and three-way mixing
configurations. A variety of electric and pneumatic
actuators are available.

Application Overview
Valve bodies are made of nodular cast iron and
are available from sizes DN 15 to DN 150.
Flanged fittings comply with DIN and BS
standards. The valve trim is made of stainless
steel. The valve packing consists of spring
loaded Teflon-Viton-Teflon V-rings.
The VG8000V valves are available in two-way
configuration for Push-Down-To-Close
operation and in three way configurations, which
are available as mixing valves.
Two-way valves have equal percentage
relationship between valve stroke and flow at a
constant pressure drop. Three-way valves have
a combination of equal percentage and linear
characteristic. An arrow is on one side of the
valve body indicating the direction of flow for
correct installation.
Varieties of electric and pneumatic actuators are
available and can be ordered as factory fitted
valve / actuator combination or separately for in-
situ installation.
Refer to this and following pages for ordering
data and additional details.
Note: It is recommended to use the correct
water treatment. Normal tap water can
mostly be used without further
preparation when contained in a closed
system and when it has been allowed to
stabilise chemically. If however, due to
water loss the system is constantly
being replenished, then the water must
be treated. Guidelines can be found in
VDI 2035.

Actuator Selection
Flow through the valve is dependent on the position of the plug, as indicated in the tables below. The
function of the actuator / valve combination is dependent upon the action of the actuator and the type of
valve used.

Pneumatic Actuator Selection
The pneumatic actuators can be combined with
two-way PDTC and three-way valve
configurations.
All actuators are reversible for Normally Closed or
Normally Open operation on a two-way PDTC
valve body.
The actuators can also be optionally equipped
with a factory fitted positioner and/or a hand
wheel. The PY-1010 positioner is direct acting and
can be used with D.A. or R.A. actuators of the
MP8000 and PA-2000 series.
The actuators are available for valve sizes:
Valves DN 15 – 40 : MP8000 series
Valves DN 15 – 150 : PA-2000 series
Mounting kits for in-situ installation: Hand
wheel, feedback assembly and auxiliary switches
are available on request.

VA1000 Electric self-adjusting actuators
The VA1000 2500N thrust non-spring return and
2000N thrust spring return valve-actuators are
self-adjusting and therefore have a greatly
reduced installation and commissioning time.
They are of modular construction 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 DN15… DN150
valves in accordance with the close-off pressures
specified.

Installation and Servicing
When mounting the VG8000V series valves,
please follow the instructions below:
•It is recommended that the valves be mounted
upright, in a conveniently accessible location.
•Do not cover the actuator with insulating
material.
•Sufficient clearance must be allowed for
actuator removal (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
VG8000V series valves with fluids other than
specified.
•On electrically actuated valve assemblies, all
wiring must be in accordance with applicable
electrical code and ordinances.
•Input lines to the actuator must be wired
correctly to open or close the valve as is
functionally required.

When servicing the VG8000V series valves, make
sure that:
•The pneumatic or electrical power to the
actuator is isolated.
•You do not touch or attempt to connect or
disconnect wires when electrical power is on.
WARNING
Shock Hazard
Disconnect the power supply before wiring
connections are made to prevent personal injury.
Equipment Damage Hazard
Make and check all wiring connections before
applying power to the system. Short circuited or
improperly connected wires may result in
permanent damage to the unit.
•No air pressure is applied to the piping system
when servicing the valve.
•No attempt is made to remove the spring of a
pneumatic actuator from its housing.
