EVRA 15 Refrigeration Solenoid Valve Plunger Armature Assembly
BAPC215047523 Solenoid armature 15.0mm Outer Dimeter with 6.5mm orifice dimeter. Used in DANFOSS Type Refrigeration Solenoid Valve. EVRA/T 10/15/20 Sevro Operation Solenoid Valve.
EVRA/T 10, 15 and 20 Refrigeration Solenoid Valve Design Function:
Servo operation
EVRA/T 10 → 20 are servo operated with a "floating" diaphragm.Thepilotorifice ofstainlesssteel is placed in the centre of the diaphragm. The teflon pilot valve plate is fitted direct to the armature .When the coil is currentless,the main orifice and pilot orifice are closed.The pilot orifice and main orifice are
held closed by the weight of the armature, the armature spring force and the differential pressure between inlet and outlet sides.
When current is applied to the coil the armature is drawn up into the magnetic field and opensthe pilot orifice. This relieves the pressure above the diaphragm, i.e. the space above the diaphragm
becomes connected to the outlet side of the valve.
The differential pressure between inlet and outlet sides then presses the diaphragm away from the main orifice and opens it for full flow. Thereforea certain minimum differential pressure is necessary
to open the valve and keep it open.
For EVRA 10 → 20 valves this differential pressure is 0.05 bar/ 0.725 psi while that of EVRAT 10 → 20 is 0 bar/psi.
When current is switched off, the pilot orifice closes.Via the equalization holes in the diaphragm, the pressure above the diaphragm then rises to the same value as the inlet pressure and the diaphragm closes the main orifice.
