Pressure Regulators


RPM Series of water pressure regulators

RPE's RPM Series of cost-effective water pressure regulators are designed to stabilise the water pressure to an appliances such as a drinks dispensers or coffee machines. Each regulator controls the outlet pressure to a preset level with reliability and precision.

For added versatility, by using RPE's dual bodies the RPM series pressure regulator can be combined with a solenoid valve, water filter, or flow sensor. For completely modular solutions the functionality of the RPM series is available in the RPE Universal Series. 

In many situations the water supply pressure to an appliance may fluctuate, especially in remote locations or industrial premises. In order to avoid the varying water flow causing variable equipment performance, water hammer or even damage to the appliance itself RPE’s water pressure regulators can be used to maintain the water pressure to within an accurately limited range. These plastic bodied water pressure regulators feature a simple robust single-stage regulator design that offers accurate outlet pressure suitable for most most such applications.  The non-adjustable design eliminates unauthorised tampering with the pressure regulator pressure setting by the end-user.

  • 0.5 bar (U.S 7.25 psi)
