The GARDENA Pressure Regulator is optimally suited to even out pressure fluctuations in the GARDENA Sprinklersystem. It combines pressure regulation and filtration in compact form. Because of this, it is especially easy to install and helps in keeping cost low. The constant water pressure of a maximum of 3.1 bar for all following components prevents damages of the Sprinklersystem caused by too high pressure. The integrated filter with pre-mounted 155-mesh-stainless-steel-sieve protects the Pressure Regulator from dirt. The removable lid makes it easy to clean or replace the filter. The recommended water flow of 0.45 to 4.3 m³ per hour offers high flexibility. Due to the 1" male thread, the Pressure Regulator can be connected with the GARDENA Quick & Easy connectors and all GARDENA pipes. The construction made from heavy-duty, glass-filled nylon ensures that the Pressure Regulator is suited for the highest quality standards. In combination with the Valve Box (Art. No. 1290-20), the Pressure Regulator can be installed under the ground.
