Johnson & Starley Pressure Valves

Within this Johnson & Starley 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 Johnson & Starley 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 Johnson & Starley safety valves are new and genuine manufacturer spares.
