The Reliance PRED330616 is a preset 3.5 bar, 15mm pressure reducing valve (PRV) from Reliance Water Controls (RWC), part of their trusted 330 domestic series. Designed for domestic potable water systems, this valve reduces high mains inlet pressure down to a safe, consistent 3.5 bar, protecting pipework, appliances and heating system components from the damaging effects of overpressure.
Factory preset and locked at 3.5 bar, the PRED330616 requires zero on-site adjustment — simply fit and go. The built-in integral strainer filters debris from the incoming supply, protecting the valve seat and extending service life without the need for a separate inline filter.
Key Features & Benefits:
- Preset to 3.5 bar — no adjustment required on installation
- 15mm compression connections for standard domestic pipework
- Integral strainer filters incoming supply and protects valve seat
- Handles inlet pressures up to 16 bar
- Suitable for domestic potable water applications
- Compact design ideal for installations where space is limited
- Manufactured by RWC — over 70 years of pressure control expertise
