Specifications
The Deep Well Pump Control Valve shall be a pilot operated diaphragm valve designed to minimize the
surges associated with the starting and stopping of deep well pumps. The valve shall be designed to close
at an adjustable rate upon pump start-up, and open at an adjustable rate upon pump shut-off. When the
valve is near the fully open position, the limit switch shall be tripped, turning the pump off. The pump shall
start and stop against an open valve. The valve shall have provisions for manual operation in the event of
power outage. Solenoid voltage shall be _________ and enclosure shall be NEMA 4 General Purpose.
The main valve shall be a hydraulically operated, single diaphragm actuated, globe or angle pattern valve.
Y-pattern valves shall not be permitted. The valve shall contain a disc and diaphragm assembly that
forms two separate sealed chambers: 1) between the diaphragm and the valve cover, and 2) between the
diaphragm and the power chamber. The diaphragm shall be constructed of nylon reinforced Buna-N, and
shall not seal directly against the valve seat and shall be fully supported by the power chamber. Rolling
diaphragm construction will not be allowed and there shall be no pistons operating the main valve or any
pilot controls.
The main valve body shall be fabricated 304L with Class D zinc plated steel flanges, utilizing stainless
steel seal welds allowing the entire flow path to be stainless steel. External steel components shall be fully
primed and painted with a stainless steel paint to prevent surface corrosion. The valve cover and all internal
components shall be fabricated 304L Stainless Steel, and the main valve trim and throttling components
(cover bearing, power chamber bearing, valve seat and disc guide) shall be Stainless Steel.
The disc and diaphragm assembly shall contain a Buna-N synthetic rubber disc with a rectangular cross-
section that is securely retained on 3-1/2 sides by a disc retainer and disc guide.
The exposed portion of the seat disc shall contact the valve seat and seal drip-tight. The disc and diaphragm
assembly must be guided by two separate bearings, one installed in the valve cover and one concentrically
located within the power chamber, to avoid deflection and assure positive disc-to-seat contact. Center
guided valves will not be permitted. All necessary repairs shall be made from the top of the valve while the
body remains in line.
The pilot control system shall be designed with a “remote-supply” feature, which is field connected to the
downstream side of the system check valve, utilizing static system pressure to operate the valve. It shall
contain a 4-Way Solenoid Pilot with a lever type Manual Operator, Single Limit Switch, separate Adjustable
Opening and Closing Speed Controls, Y-Strainer and Isolation Ball Valves on the Y-Strainer inlet and all
body connections. The pilot control system shall utilize copper tubing and brass fittings.
The valve shall be Watts ACV Model S513-6 / S6513-6 (Globe) or S1513-6 / S61513-6 (Angle) Deep Well
Pump Control Valve.
