● Function
Pressure reducing valve is a device which reduces and stabilizes the upstream pressure to an adjusted
Downstream pressure , when the entering pressure from the public mains is too high and variable, pressure
Reducing valve stabilizes the downstream pressure to adjusted one.
Possible variations of the upstream pressure do not influence the adjusted downstream pressure.
This range of pressure reducing valves allows the operator to adjust the downstream pressure to a set figure.
● Use
Pressure reducing valves are suitable for domestic water services, heating and air-conditioning plats,
Compressed air system. They can be with water, compressed air and no-aggressive fluids.
TASAN Pressure reducing valves comply with the requirements of Council Directive 97/23/EC (PED)and
CE marking is not requested according to art.3 clause 3 of DL 25/02/2000N.93.
(In the type-testing according to PED Council Directive. It is necessary that pressure reducing valves were
Approved as a part of the installation)

● Installation

For the best use and duration of the system, it is necessary to comply with the following instruction on installation, with the national regulations and with relevant local requirements.
-Place of installation has to be protected from frost and has to be easily inspectable
-Install the pressure reducing valve on the private, water system, immediately downstream of the water meter.
-It would be better to install shut-off valves upstream and downstream of the pressure reducing valve,to facilitate the maintenance operations.
-In order to protect pressure reducing valves from overpressure, install a check valve immediately downstream of the pressure reducing valve
-In case of water heater downstream of the pressure reducing valve, install an expansion vessel between the valve and the water heater.
-Pressure reducing valve is not a safety device. It would be better to install all the necessary safety relief valves.

 

Please duly note, the downstream pressure of the reducing valve has not to be higher than the maximum working pressure of the devices installed in the private water system in order to avoid possible damages malfunctions.

 

● Instruction on Installation

1. Before installing the pressure reducing valve, open all the outlets to flush the system and expl any air left in piping
2. Install shut-off valves upstream and downstream to facilitate maintenance operations for the right flow direction, use the arrow stamped on the body
3. Tasan pressure reducing valve can be installed in either vertical or horizontal piping. It can be installed also upside down.
4. The pressure reducing valve is equipped with a threaded connection suitable for a pressure gouge. It is possible to unscrew the plug made by.
5. Nylon PA6 in order to install a pressure in the size of ¼”. In the such a position, the pressure gouge shows the downstream pressure of the reducing valve. The whole range of Tasanpressure reducing valve are tested and adjusted with a downstream pressure of 3 bar, it is possible to change the downstream pressure by means of the adjusting device. PRV
