Frequently Asked Questions
What is a semi-lift solenoid valve?
A semi-lift valve uses a two-stage operation: the solenoid directly lifts a small pilot orifice first (like a direct acting valve), then system pressure assists in opening the main diaphragm (like a pilot operated valve). This gives zero-pressure startup capability with high full-flow capacity.
What is the advantage over standard pilot operated valves?
Standard pilot operated valves require a minimum differential pressure (typically 0.3 bar) to open. Semi-lift valves can start from zero differential pressure, making them ideal for vacuum, low-pressure, and variable-pressure systems.
What sizes are available in the MCN Series?
The MCN Series is available in port sizes from 1/2" (DN15) to 2" (DN50). For larger sizes, our standard PCN Series pilot operated diaphragm valves are recommended.
