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 t 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>
