What it is

The Caleffi A314437CST is a pressure relief valve set to open at 3 bar, with 1/2" x 15mm connections and an integrated gauge port. It relieves excess pressure from a heating or plumbing system by discharging water once the set pressure is reached. The valve body carries an integrated gauge port.

Before you order

  • Confirm 3 bar is the correct relief pressure for the system.
  • Check that the 1/2" x 15mm connections match the pipework or fitting.
  • Confirm a gauge port is required at this position.
  • Check the part number A314437CST against the valve being replaced.
