DESCRIPTION Low Flow Circuit Sentry Model ACL valve is designed to automatically control the flow in piping systems to a selected preset limit. As pressure differential increases, a cartridge inside the valve body reduces the flow area to accurately maintain the preselected flow rate. Flow Operating Range: 0.25 – 3.
PAGE 3
Prior to coil commissioning and operating the Flow Limiting Valve, adjust cartridge to the desired flow rate between 0.25 GPM to 3.8 GPM. 1. 2. 3. 4. Loosen screw (a) position. Rotate plastic dial (b) to the desired flow rate. Increments marked on variable orifice are in GPM. Re-tighten screw (a) with dial set at the desired flow rate. Install the cartridge as shown below.
PAGE 4
Should the Flow Limiting Valve require cleaning or changing the flow rate, follow the instructions below: 1. 2. 3. 4. 5. Loosen and remove the cap from the valve body. Pull the cartridge assembly from the valve body for cleaning or flow adjustment. Check the cartridge by pushing the orifice washer into the cartridge housing several times to make sure spring is functional and to dislodge any possible debris. Rinse with water if necessary.
