Recently our competent workshop technicians have been testing this EL-O-MATIC ‘F’ series double acting pneumatic actuator c/w declutchable manual override gearbox, DVC6200 positioner, 67CFR filter-regulator and a lock-up valve. The latter has a built-in equalising valve function to ensure the pressure is equalised across the pistons when the manual override is employed.
Destined for use within a Petrochemical facility.
