The Type 14450 precision relief valve has been designed to provide accurate over pressure protection in systems
operating at pressures of up to 700 bar and fl ows of up to 45 l / m.
Precision relief valves have very high sealing forces along with accurate and narrow dead bands. Precision relief
valves should be used in preference to sprung relief valves where there is risk of vibration induced leakage or
where dead bands are important to system safety performance. Sprung relief valves typically will have a narrow
dead band when tested on a static dead weight tester but will have a much wider dead band under fl owing
conditions that will require a signifi cant drop in system pressure to enable the valve to reseat.
The fl oating poppet design enhanced by the use of linear bearings produces characteristics which are non fl ow
dependent and ensures long life with repeatable performance.
Installation and removal of system pipe work is simplifi ed by the right angled porting confi guration.
