3.4 Installing Bonnet/Gate Assembly to Valve Body
a)
Carefully lift bonnet/gate assembly over the valve body and stab the gate in the space between the seats.
A seat spreader aid may sometimes be necessary to spread the seats to make it easier for installing the
gate. Once the gate has started between the seats it would easily slide all the way down until the bonnet
comes into contact with the valve body.
