FTV-S (Straight) & FTV-A (Angle Body)
Tri-Service Valve
INSTALLATION:
1The valve should be mounted to a spool piece on the discharge
side of the pump. Spool piece required is based on a minimum
recommended space of 12" for pump sizes 2" x 2" to 6" x 6" and 24" for
pump sizes 8" x 8" to 12" x 12".
2It is not recommended to mount a valve directly to the pump as
this could cause undesirable noise in the system.
3Suffcient clearance around the valve should be left for valve
removal or repair.
4Install valve in the direction of the fow arrows on the valve body.
5The valve can be mounted to fanged equipment using Gruvlok
Flange Adapter or industry standard grooved coupling, suitable for
system pressure and temperatures encountered.
6The Gruvlok Tri-Service valve bodies have anti-rotation lugs on the
inlet and outlet. These lugs, combined with the Flange Adapters,
provide a ridged rotation free installation.
7The valve body has been designed to handle the weight of the
pump on vertical in-line installations. The body is not designed to
support the piping weight. It is recommended that the piping be
supported by hangers. Pipe supports should be provided under the
valve and strainer bodies.

1Open valve at least one complete turn,
2Remove the body bolts from valve body
using Allen Key.
3Rotate one half of the valve body 180°
making sure the lower valve seat and “O”
Ring stay in position. Inspect the “O” Ring for
any cuts or nicks and replace if necessary.
4Replace body bolts and torque evenly to
70 ft./lbs.
FLOW MEASUREMENT
Where approximate indication of fow is acceptable the Gruvlok Tri-Service valve can be used.
FLOW MEASUREMENT VALVE IN WIDE OPEN POSITION
Measure and record the differential pressure across the valve using a Flow Meter with high
pressure range transducer or pressure gauges with PMP adapters.
Refer to Tri-Service Performance Curves with valve in full open position (See Determining Flow
Rate with Valve in Throttled Position Section on page 165). Locate Pressure Differential on left
hand side of chart and extend line horizontally across to valve size being used. Drop line
vertically down and read fow rate from bottom of chart.
CAUTION:
Safety glasses should be used and the probe should
not be left inserted into fttings for prolonged periods
of time (overnight, etc.), as leakage from the PMP may
occur when probe is removed.
