How To Install A Prv Valve
How to install a water force per unit area reducing valve?
Operation, installation and commissioning of a water pressure reducing valve
To explain how to install a pressure reducing valve , we will take as an example the VALFONTA VD model, designed to continue the outlet pressure abiding by means of the regulating piston.
It works under the principle of direct action; Upstream pressure reaches the valve and presses the bushing upwards, actuating the joint. Once the valve is airtight, the adjusting spiral must be turned clockwise. This causes the spring to move, which acts on the bushing and the gaskets, opening the valve until the necessary pressure is achieved. Any variation in inlet pressure volition be absorbed past the valve by compensating the ii parts of the bushing, joined past means of a compensating hole.
Installing a pressure reducing valve like this
It is vitally important to scrupulously clean the pipeline before installing the valve, to prevent any small chemical element or impurity from altering its right operation.
It is also highly recommended to install a filter at the valve inlet for protection. This should be installed in a horizontal piping; the direction of flow must correspond to the management shown by the arrow on the valve trunk.
Parts to support the valve should be placed as close to it every bit possible, but never attached to the valve or actuator, in order to eliminate unnecessary stress.
How to install a pressure reducing valve: Commissioning
The offset step for a right outset-upward is to open the shut-off valves very slowly, in guild to avoid any water hammer during the process. So, the regulation screw must be turned until the required pressure is reached.
If the spring is increased, the outlet pressure level is increased; it must be turned clockwise to increase it and counterclockwise to decrease it.
This type of pressure reducing valve has a long list of applications: chemical laboratory facilities, water distribution systems, wastewater installation, industrial, compressed air, sprinkler systems, fuel oil …
