Specifications
The Deep Well Pump Control Valve with Pressure Relief Feature shall be a pilot operated diaphragm valve
designed to minimize the surges associated with the starting and stopping of deep well pumps, and act as a
Pressure Relief Valve during the pumping cycle. 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 and cover shall be Ductile Iron ASTM A536, and all internal cast components shall be
Ductile Iron or CF8M (316) Stainless Steel. All Ductile Iron components, including the body and cover, shall
be lined and coated with an NSF 61 Certified Epoxy Coating applied by the electrostatic heat fusion process.
All main valve trim and throttling components (cover bearing, power chamber bearing, valve seat and disc
guide) shall be Stainless Steel. The valve body, cover, and power chamber must be machined with a 360-
degree locating lip to assure proper alignment.
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, Pressure Relief Pilot,
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 adjustment range of the Pressure Relief Pilot shall be 20-200 psi.
The valve shall be Watts ACV Model M513-14 / M6513-14 (Globe) or M1513-14 / M61513-14 (Angle) Deep
Well Pump Control Valve with Pressure Relief Feature.
