Installation Recommendations for
GROOVED END VALVE CONNECTIONS
Grease the pipe ends, valve ends and rubber gasket lip
with grease, graphite paste or similar grease. Slip the
rubber gasket over the pipe end of each joint. Slide the
gasket past the grooves. Position the grooved end valve
between the pipe ends and slide the gaskets back into the
central spanned position.
All products have a flow direction arrow. Make sure that
it is pointing in the direction of the flow. Apply grease
on the outside of the gasket. Install housing clamps over
the gasket
- insert bolts and nuts.
Tighten nuts evenly, using socket or other wrench. Tight-
en so that housing clamps come together evenly. The
connection is complete when housing clamps meet metal
to metal. Further tightening of bolts is not necessary.
Pre - assemble large diameter multi - segment housing
clamps loosely and install them as half - housings. Take
up evenly from top to bottom on alternate bolts.
Correction for Liquids
Applies to liquids other than water. Correct the measured
flow (q) by the density (
γ ) according to this formula.
See Figure 4
Sizing a Balancing Valve
When the differential pressure and design flow are
known, use this formula to calculate Cv value.
