The Giacomini R153PX006 pressure regulator is an automatic valve that reduces and maintains a steady pressure in water or compressed air systems, protecting equipment and ensuring a consistent flow. It is recommended for sanitary installations, drinking water supply, HVAC systems, irrigation, oil-free compressed air networks, and fire protection systems, in accordance with local regulations.
This unit features 1 1/4-inch (G 1-1/4”F) connections and operates at a maximum pressure of 25 bar. The outlet pressure can be adjusted between 1 and 5.5 bar, with a factory setting of 3 bar. Adjustment is easily made via a screw located beneath the top cover. The body is made from durable nickel-plated brass, and the pin is made from glass-reinforced technopolymer. Seals are made from EPDM, while the sealing seat is made from AISI 303 stainless steel, ensuring consistent performance and long service life.
The product includes a connection for a pressure gauge (RP 1/4”) and complies with the European standard EN 1567. It can operate at temperatures up to 130°C and has a maximum regulated flow rate of 5.8 m³/h (96 liters per minute).
