Frequently Asked Questions
What materials are suitable for different media?
EPDM is recommended for water; NBR is suitable for oil, water, and air; and FKM is suitable for oil and air.
Can the solenoid valve be installed vertically?
While optional, a vertical solenoid system is recommended for optimal function.
What are the maximum temperature ranges?
The media temperature can range from -30 to 140 °C (for some specific applications).
How does the solenoid valve operate when voltage is applied?
When connected, the diaphragm closes the main orifice because the pressure across it builds up via the equalizing orifice.
