Automatic Control Valves The Automatic Answer to Fluid Control watts.
INTRODUCTION Specifying Automatic Control Valves is a critical balancing act. On one hand, you must have the utmost confidence not only in the quality and performance of the valve, but also in the knowledge and “hands-on” expertise of the manufacturer. On the other hand, product reliability must be unquestioned, meeting the exact design parameters specified. Orders must be shipped as promised, keeping your job on track, and after-the-sale support is essential.

SPECIFICATIONS WATTS ACV FEATURES Standard Production Valves: * Wide range of sizes 1 1/4" - 24" * Fused epoxy coating 100% inside and out.
FLOAT CONTROL 110-10 (Globe) / 1110-10 (Angle) FLOAT CONTROL – MODULATING (CONSTANT LEVEL) ➡ CLOSES VALVE Flow Direction Shown: Under the Seat Optional ‘R’ Flow Over the Seat: ➪ OPENS VALVE The ACV 110-10 maintains a constant level in storage tanks and reservoirs. Valve controlled flow into the tank is proportional to discharge flow, keeping the tank full. NOTE: The modulating float control ACV 10-11, is remote mounted.
SOLENOID CONTROL 113-12 (Globe) / 1113-12 (Angle) ➡ CLOSES VALVE ➪ OPENS VALVE 1 4 SOLENOID ON/OFF (OPEN/CLOSE) Sizes 1 / " - 4" Operated by a 3-way solenoid, the main valve opens fully or closes drip-tight depending upon the actuation position of the solenoid, energized to open/energized to close. The valve may be remotely operated by timers, relays, probes or any triggered device to the solenoid. NOTE: Energized to open valve. Optional: energized to close valve.
PUMP CONTROL 113-46 (Globe) / 1113-46 (Angle) BOOSTER PUMP CONTROL (Valves 4" and smaller) Solenoid operated pump control for controlled opening and closing on pump start-up and shut-down. Equipped with hydraulic check feature to close valve on pressure reversal and shut-off pump in event of pump failure. Valve and pump operations are interlocked by a limit switch assembly. NOTE: Energized to open valve. At time of order, advise factory actual system working pressure for correct solenoid selection.
PUMP CONTROL 413-21 (Globe) / 1413-21 (Angle) BOOSTER PUMP CONTROL / MECHANICAL LIFT CHECK Solenoid operated pump control for controlled opening and closing on pump start-up and shut-down. Equipped with mechanical liftcheck feature to close valve the moment flow stops, preventing reverse flow. Valve and pump operations are interlocked by a limit switch assembly. NOTE: Energized to open valve. At time of order, advise factory actual system working pressure for correct solenoid selection.
PUMP CONTROL 513-6 (Globe) / 1513-6 (Angle) DEEP WELL PUMP CONTROL The ACV 513-6 pump control valve starts in an open position during pump start-up, purging the deep well of air and debris to atmosphere. Controlled closing of the valve, opens the mainline check valve, gradually increasing line pressure. The valve reopens during shut-down cycle to gradually decrease line pressure and prevent shock. Valve and pump operations are interlocked by a limit switch assembly. NOTE: Energized to close valve. Max W.P.
RATE OF FLOW PRESSURE REDUCING 114R (Globe) / 1114R (Angle) RATE OF FLOW (“R” indicates over the seat flow) Maintains a constant flow rate, adjustable, regardless of fluctuations in line pressure. The rate of flow pilot senses the differential pressure across a thin edged orifice plate mounted in the valve inlet flange. It responds to changes in pressure and modulates the main valve to maintain the desired flow. SPECIFY: Desired flow rate at time of order.
PRESSURE REDUCING 115-2 (Globe) / 1115-2 (Angle) PRESSURE REDUCING / SUSTAINING Automatically reduces a higher inlet pressure to a constant lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. Equipped with a pressure sustaining control which prevents the upstream pressure from dropping below a preset minimum.
PRESSURE REDUCING 115-4 (Globe) / 1115-4 (Angle) PRESSURE REDUCING / SOLENOID ON-OFF Automatically reduces a higher inlet pressure to a constant lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. Equipped with a solenoid override feature allowing for electrical on-off operation of the valve. NOTE: Adjustment range: Standard: 20-175 psig Optional: 0-30 psig 100-300 psig (uses stainless steel control) Solenoid max W.P.
115-74 (Globe) / 1115-74 (Angle) PRESSURE REDUCING / LOW FLOW BY-PASS VALVE Automatically reduces a higher inlet pressure to a constant lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. Equipped with a low flow by-pass feature which bypasses the main valve pressure function for low flow conditions.
PRESSURE RELIEF / SUSTAINING 116 (Globe) / 1116 (Angle) PRESSURE RELIEF / SUSTAINING Installed on a by-pass line, mainline pressure is accurately controlled by relief of excess pressure. Installed in a mainline it prevents upstream pressure from dropping below a preset minimum. NOTE: Adjustment range: Standard: 20-200 psig Optional: 0-30 psig 100-300 psig Additional relief/sustaining functions: - 116FM/1116FM (U.L. listed/F.M.
SURGE RELIEF / CHECK 116-52 (Globe) / 1116-52 (Angle) SURGE ANTICIPATOR RELIEF / REMOTE SENSE Used in pumping systems to protect equipment from damaging pressure surges or waves caused by rapid changes of flow within the pipeline. The 116-52 responds by opening at a preset low pressure setting, allowing for quick relief of the returning high pressure wave. The valve remains open as the integral accumulator is charged and then closes.
ALTITUDE 127-1 (Globe) / 1127-1 (Angle) ALTITUDE VALVE - ONE WAY FLOW (TANK FILL) Provides automatic filling of elevated tanks or reservoirs. When the altitude control senses a drop in level below the predetermined setpoint the valve opens to fill tank. Supply pressure is greater than static head pressure. Discharge of the tank is by a separate line. NOTE: Adjustment range: 5-20 FT. 10-75 FT. 50-200 FT.

ENGINEERING DATA / SIZING INSTALLATION RECOMMENDATIONS AND REQUIREMENTS VERTICAL INSTALLATIONS Avoid mounting valves 6" and larger in a vertical discharge position (valve stem horizontal or cover pointed sideways). If your installation requires this mounting position consult the factory or specify at time of order. ISOLATION SHUT-OFF VALVES Butterfly or similar type valves should be installed in the line upstream and downstream of the automatic control valve to allow for maintenance service.
VALVE SIZING found on the vertical axis. (Your maximum differential pressure will be the highest inlet pressure minus the desired outlet pressure, this is also known as the delta P.) To properly size an automatic control valve you need to know the following: • Highest and Lowest inlet pressures • Outlet pressure • Maximum flow requirements • Minimum flow requirements Step 5: From this point draw a horizontal line until you intersect with the line corresponding to the valve size as selected in step 3.
PRESSURE DROP INDEX - PRESSURE REDUCING VALVES Calculate the pressure difference by subtracting the desired outlet pressure from the maximum inlet pressure. Find the number on the pressure difference line and note the outlet pressure index number. This is the lowest outlet pressure setting allowed without failing into the cavitation zone. Design of the WATTS Automatic Control Valve minimizes potential valve damage that can be caused by cavitation. Avoid continued operation within the cavitation zone.
