DESCRIPTION
The ADCA PRV47 pilot operated pressure reducing
valves are designed for use on steam, compressed air,
nitrogen and other gases compatible with the
construction and they can be installed on pressure
reducing stations throughout all industries.
Connections are flanged or threaded.
MAIN FEATURES
Robust complete steel or stainless steel construction.
Suitable for dead end conditions.
Guided piston and valve stem.
Hardened plug.
OPTIONS:
USE:
Soft faced valve plug for gases and steam
Special pressure top for low pressures
Drain connection in bottom cover
Stellited plug and seat
Saturated steam, compressed air and
other gases (Group 2) compatible with
the construction ( except oxygen).
AVAILABLE
MODELS: PRV47 - standard model for steam
PRV47G -compressed air and gases
VALVE SIZES: DN15 to DN50
CONNECTIONS: Flanged EN 1092-1 or ANSI
Threaded BSP, NPT, SW.
INSTALLATION: Horizontal installation.
An "Y" strainer, steam separator and Maximum upstream pressure (steam) : 25 bar
steam trap should be provided Maximum upstream pressure (air) : 31 bar
upstream the valve. Maximum downstream pressure: 17 bar
See IMI, installation and maintenance Minimum downstream pressure : 0,35 bar*
instructions. * 0,07 bar with low pressure top (limited at 7 bar inlet).
ORDER Pressure and temperature may change if soft seating
REQUIREMENTS: Type of fluid or piston rings are used.
Maximum operating temperature USEFUL NOTES ON VALVE AND PIPE SIZING

requirement - please consult.
The balance pipe connection is recommended to enter
the downstream pipe at a minimum of 1 meter from valve.
A spool piece can be supplied to house the balancing
