Saunier Duval Pressure Valves

Within this Saunier Duval Pressure Valves category we list PRV's also known as Pressure or Expansion Relief Valves and Safety Valves along with Pressure Reducing Valves. These PRV's act as a safety device within Saunier Duval sealed system boilers and Combi's and allow excessive expansion in the system to be discharged safely. Some appliances have a combined safety pressure and temperature relief valve which acts in the same way but also deal with excessive temperature. All our Saunier Duval safety valves are new and genuine manufacturer spares.
