Pressure reducing valves

Pressure reducing valves for residential, commercial, and industrial water systems. These valves stabilise downstream pressure at a defined setpoint and remain unaffected by upstream pressure fluctuations, ensuring reliable system protection. The portfolio includes compact brass models for domestic water and appliance protection (DRV, DRV/E, DRVN, REDUBAR, PRECISIO) and combined units with integrated isolation and check valves for fast installation (REDUBLOC). For higher flow rates or network-level control, ductile-iron flanged regulators (DRVD, PN16–PN40) offer robust performance in collective or industrial installations. Depending on the model, adjustable pressure ranges cover 1.5–6 bar, 1.5–5 bar, 1.5–4 bar, and up to 12 bar. Key features include compensated seats for stable regulation, integrated filters, pressure gauge ports, multi-threaded connectors, and low-noise operation. Materials such as CW617N and DZR brass, technopolymer caps, EPDM/NBR diaphragms, and stainless-steel filters ensure durability. Watts pressure reducing valves help minimise water hammer, reduce noise, and maintain efficient, consistent operation across diverse applications.
