body, stainless steel main valve trim and control pilot system and rubber
parts of Viton or Buna-N. When diaphragm fails, the valve shall close.
Valve shall have position indicator, pilot circuit strainer, and pressure
gage quick-disconnect fittings located in valve inlet, outlet, and cover.
2.13.11
Surge Control and Check Valves
ANSI Class 150, with flanged end connections, and position indicator.
Hydraulically operated, pilot-controlled, diaphragm type, nonsurge globe
valve with closing time of one to five seconds; locate on the discharge
side of the transfer pump. Valve shall automatically prevent reverse flow
and open at a controlled rate to keep pump starting surges from shocking
downstream equipment. Opening rate shall be adjustable from 5 to 60
seconds. Aluminum alloy 6061-T6 or 356-T6 valve body, stainless steel main
valve trim and control pilot system; rubber parts of Viton or Buna-N.
Provide orifice plates by valve manufacturer. When diaphragm fails, the
valve shall open. Valve shall have position indicator, pilot circuit
strainer, and pressure gage quick-disconnect fittings located in valve
inlet, outlet, and cover.
2.13.12
Solenoid Control Valves
ANSI Class 150, with flanged end connections, and position indicator.
Hydraulically operated, pilot-controlled, diaphragm type globe valve, with
a tight shutoff down to 1379 kPa (gage) 200 psig operating pressure. When
energized, the solenoid controls shall cause the main valve to open and
function normally. When deenergized, the solenoid controls shall cause the
main valve to close, providing a driptight shutoff. Provide NEMA 7
main valve trim and control pilot system; rubber parts of Viton or Buna-N.
When diaphragm fails, the valve shall close. Valve shall have position
indicator, pilot circuit strainer, and pressure gage quick-disconnect
fittings located in valve inlet, outlet, and cover.
2.13.13
Truck Fueling Flow Controller Valve
ANSI Class 150, with flanged end connections, and position indicator.
Hydraulically operated, pilot-controlled, diaphragm type globe valve,
capable of limiting flow rate regardless of varying inlet pressures.
Provide with an adjustable low flow start period, and thermal-relief
function. Functions shall be externally adjustable. Provide NEMA 7
solenoids for truck fill high level shutoff and hand held deadman control
system. Aluminum alloy 6061-T6 or 356-T6 valve body, stainless steel main
valve trim and control pilot system; rubber parts Viton or Buna-N. When
diaphragm fails, the valve shall close. Valve shall have position
indicator, and pilot circuit strainer.
2.13.14
Aircraft Fueling Flow Control Valve (4 Inch)(100 mm)
ANSI Class 150, with flanged end connections, and position indicator.
Hydraulically operated, pilot-controlled diaphragm type globe valve,
capable of regulating downstream pressure to a maximum of 345 kPa (gage) 50
psig using a remote pressure signal from a venturi. The valve shall have
opening speed controllers. Functions shall be externally adjustable.
Provide NEMA 7 solenoid control, suitable for deadman operation. Provide
safe hand held deadman control with 7.50 meters 25 feet cable. Aluminum
alloys 6061-T6 or 356-T6 valve body. Stainless steel main valve trim and
control pilot system; rubber parts of Viton or Buna-N. Provide venturi for
each fueling valve. When diaphragm fails, the valve shall close. Valve
