Product Details

Part NumberPull and Hold Master Control with Toggles
AD14PH*ALFSThe Pull and Hold master control isolates the air supply to allow for more effective emergency shut-down if required by fusible plug or end-of-line remote. This style should only be used on properly maintained systems with minimal airline leakage. To operate, first select which compartment toggle to open, then pull and hold master control knob until system is fully charged. When master control is released it springs to neutral position locking in the system air while blocking the supply air. If additional compartment valves need opened, pull and hold master control knob while selecting desired toggle. Once system is charged, release master control. Shut down same as Push/Pull.
*Complete part number by inserting required number of compartments; e.g. AD14PP4ALFS = 4 compartments. Note: Up to 5 compartments standard for master control styles and up to 7 compartments for toggle only style.
** Values shown are test values. Actual results may vary due to service conditions. Water vapor or condensation in air lines will effect performance.
