2. Centering Clamp for
Electrofusion Fittings

The Centering Clamp is used to
properly align the Electrofusion
Fittings to the pipe during the
fusion process. It is designed to
evenly distribute the clamping
force applied by the operator.

3. Slide Gate Valve

The Slide Gate Valve consists of a
sliding gate housed between two

at bodies; pressure is held rmly

by two O-rings, one above and one

underneath. The valve is tted with

an internal pressure equalizer which
allows easy opening when pressure
varies between the upper and lower
parts of the valve. To open and close
the valve, turn the operating square
approximately a quarter turn.

!

CAUTION: Never leave the
valve with the gate in the closed
position when not in use. In
the event that the gate is stuck,
loosen the screws holding the two
valve bodies, bring the gate to the
open position and retighten the
screws.
