Installation, Maintenance & Operating Guide

***WARNING***

For your personal safety and protection, it is important that you

observe the following precautions before removing the valve

from service or disassembling the valve.

1. Never adjust exterior screws or bolts while the valve

is pressurized.

2. Keep hands and fingers out of valve.

3. It is possible that residual media or pressure may be

trapped inside the valve cavity. Ensure that the line and

valve are properly depressurized and be aware of any

residual harmful substances that may still be present.

4. To depressurize the valve:

a. Repeatedly open and close the valve to both drain the

line and relieve any residual pressure in the valve

cavity. Leave the valve in the open position.

b. Repeat this procedure once the valve is removed from

the line and standing in the vertical position.

5. Exercise caution when handling a valve that has been used

to control hazardous media. It is recommended that the

valve and line be thoroughly flushed prior to removal

and/or disassembly. Cycle the valve slowly while flushing

to clear the cavity.

***CAUTION***

3700 Series Ball Valves feature a double "o"-ring stem with

non-adjustable packing. Do not remove the stem retainer plate

while the valve is under pressure.
