SHSUOTE
DESCRIPTION
The shsuoTe ModelSCRDpressureReducingcontrolautomaticallyreduces
a higher inlet pressure to a lower outlet pressure. It isa direct acting,
spring loaded, diaphragm type control that operates hydraulically or p neu- mati call y. It may be used as a self-contained valve oras a pilot control for a c la-val main valve. It will hold a constant downstream pressure within
very close pressure limits.
OPERATION
The sCRD pressure Reducing control is normally held open by the force of the compression spring above the diaphragm; and delivery pressure acts on the underside of the diaphragm. Flow through the valve responds to
changes in downstream demand to maintain a pressure.
INSTALLATION
The sCRD Pressure Reducing control may be installed in any position. There is one inlet port and two outlets, for either straight or angle install a- tion. The second outlet port can be used fora gage connection. A flow arrow is marked on the body casting.
ADJUSTMENT PROCEDURE
The sCRDpressure Reducingcontrolcan be adjusted to provide adel iv-
ery pressure range as specified on the name plate.
pressure adjustment is made by turning the adjustment s crew to vary the spring pressure on the diaphragm. The greater the compression on the
spring the higher the pressure setting.
1. Turn the adjustment s crew in (clockwise) to increase delivery pressure.
2. Turn the adjustment s crew out (counter-clockwise) to decrease the delivery pressure.
3. when pressure adjustment is completed tighten jam nut on adjusting screw and replace protective cap.
4. when this control is used, as a pilot control ona
shsuoTe main valve, the adjustment should be made
under flowing conditions. The flow rate is not critical, but generally should be somewhat lower than normal in order to provide an inlet pressure several psi higher than the desired setting
