which in themselves might directly or indirectly cause

severe personal injury or property damage.

GENERAL INFORMATION

The following instructions are designed to assist in

unpacking, installing and performing maintenance as

required on FlowTop general service control valves.

Product users and maintenance personnel should thor-

oughly review this bulletin prior to installing, calibrating,

operating, troubleshooting or performing any mainte-

nance on the valve or actuator. Separate instructions

cover additional features such as positioners, solenoid

valves, limit switches, etc.

To avoid possible injury to personnel or dam-

age to valve parts, WARNING and CAUTION

notes must be strictly followed. Modifying this

product, substituting non-factory parts or us-

ing maintenance procedures other than out-

lined could drastically affect performance and

be hazardous to personnel and equipment and

may void existing warranties.

CAUTION: The FlowTop is a general service, light-

duty valve and is not intended for severe ser-

vice applications such as cavitation, flashing or

extreme noise levels. Refer to the FlowTop Con-

trol Valves technical bulletin for application

guidelines and other limitations.

WARNING: Standard industry safety practices

must be followed when working on this or any

other process-control product. Specifically, per-

sonal protection and lifting devices must be used

as warranted.

NOTE: Selecting the proper fastener material is the

responsibility of the user. Typically, the supplier does

not know the valve service conditions or environment.

The user therefore must consider the material’s

resistance to stress corrosion cracking in addition

to general corrosion. As with any mechanical

equipment, periodic inspection and maintenance

is required.
