Here is the choice of ambient temperatures during which the solenoid valve is intended to function. Oftentimes, only the utmost ambient temperature is specified.
The valve entire body substance encloses the valve internals and presents structural support. This portion will need to have significant toughness to face up to the pressure of the process line. Additionally, it truly is right exposed to the atmosphere and needs enough corrosion and weathering resistance.
MOPD signifies the difference in pressure between the inlet and outlet ports where the solenoid valve is meant to run.
