Operation

These valves are used for hot or cold water and for water

glycol mixtures up to 50%.

Note: These valves are intended to control equipment

under normal operating conditions.

Where failure or malfunction of the valves could

lead to an abnormal operating condition that

could cause personal injury or damage to the

equipment or other property, other devices (limit or

safety controls) or systems (alarm or supervisory

systems) intended to warn of or protect against

failure or malfunction of the valves must be

incorporated into and maintained as part of the

control system.

Mounting Instructions

General Guidelines

In addition to general installation instructions, please

observe the following points:

• Ensure that valve body and piping are free of

impurities.

• Pay attention to position of the valve relative to the ow

direction.

• Ensure that threaded connections of valve and piping

are tighten.

• Ensure installation without tension and torque.
