Válvulas solenoides de control directo normalmente cerradas nbr buna viton fkm ptfe teflon epdm
Normally closed 2-way solenoid valves with direct control Main components: body with main orifice, quill assembly + core assembly mobile (kit normally closed), coil.
Operation:
The 2-way solenoid valves normally closed with direct control have an inlet fitting and a fitting for use. The mobile core, on which a seal gasket is mounted, directly opens and closes the main orifice of the solenoid valve. When the coil is not powered, the mobile core is in such a position to close the orifice not by putting the passage of the fluid.
On the other hand, when the coil is powered, the mobile core moves to a position that opens the orifice allowing the passage of the fluid.
Note:
In this family of solenoid valves, an increase in pressure causes an increase in the force required to open the valve: if the pressure difference between the supply and use is greater than the maximum value for which the solenoid valve, the latter may not open even when the coil is powered.
