14. BENCH RANGE
The actuator bench range for spring diaphragm actuators is the operating air pressure range under no load for the rated stroke. The air pressure at which the actuator stem starts to move is known as the bench initial pressure. Increasing air pressure moves the actuator through its rated stroke. The pressure of the diaphragm at full rated stroke is the bench final pressure. The difference between the two pressures is the actuator bench range. The most common bench ranges (also called spring ranges), are 3-15 psi and 6-30 psi. Other spring ranges are utilized extensively throughout the industry to provide additional thrust as required by system requirements.”

Aktuator se sastoji od membrane koja se popotiskuje vazduhom i koja deluje nasuprot opruge. Kako se vazdušni pritisak na dijafragmu poveća sa 3 na 15 funti po kvadratnom inču [psi], igla ventila će se pomeriti sa otvorenog na zatvoreno.
