INTRODUCTION

The APOLLO® Iron Gate valves covered in these guidelines are bolted bonnet, outside
screw and yoke – rising stem and inside screw – non rising stem valve types. They are
used to start or stop the flow of fluid in a piping system. The valve is operated from a
handwheel. Gate valves should always be used in the full open or full closed position.
Flow through the valve is stopped by forcing a wedge (disc) down between the tapered
seat rings.

In OS&Y rising stem valves, the gate is attached to a threaded stem with a handle that
connects to the yoke element. As the operator rotates the handle counterclockwise, the
stem rises out of the handle, opening the gate. A clockwise rotation of the handle moves
the stem back into the gate and closes the valve. When the stem is no longer protruding
beyond the handle, the gate valve is closed. The advantage of using an OS&Y gate valve is
that you can visually see if the valve is open or closed by the position of stem.

In Non-rising stem valves, the stem is held in place between the bonnet and stuffing box.
The stem threads are engaged with the internal threads of the gate. A clockwise rotation
of the handle moves the gate down the stem and closes the valve and a counterclockwise
rotation opens the valve. The advantage of using a Non-rising stem gate valve is when
there is limited space for installation.

The APOLLO® Iron Gate valves have approval to NSF 372 “Drinking Water System
Components” and NSF 61 “Drinking Water System Components-Mechanical Devices”.
