In most cases it is beneficial to have a "balanced poppet" in a direct acting valve. Less force is needed to move the poppet because all forces on the poppet are nullified by equal and opposite forces. The solenoid coil has | In most cases it is beneficial to have a "balanced poppet" in a direct acting valve. Less force is needed to move the poppet because all forces on the poppet are nullified by equal and opposite forces. The [[solenoid]] coil has to counteract only the spring force. Marotta direct acting solenoid valves use a balanced poppet to keep solenoid coil size and power requirements to a minimum. <ref name="balanced_poppet_design_reference">"[http://www.marotta.com/tech-info-a-faqs/balanced-poppet.html What is a Balanced Poppet? on Marotta.com]."</ref> | ||
