The Type 14450 precision relief valve has been designed to provide accurate pressure control in systems operating at pressures up to 800 bar and flows of up to 45 litres/min (dependant on pressure). The floating poppet design enhanced by the use of linear bearings produces characteristics which are non flow dependent and ensures long life with repeatable performance.
 |
Floating poppet design produces reseating at 90% of cracking pressure (Static test conditions).
|
|
The main spring load is not transmitted to the seat, thus reducing distortion and wear.
|
|
Design characteristics are not flow dependent; producing a near linear response to increasing flow.
|
|
Long life and repeatable performance are ensured through the use of hardened elements operating in a linear bearing cage.
|
|
Installation and removal of system pipework is simplified by the right angled configuration.
