Safety Guidelines; Description Of Function; Application; Technical Data - Honeywell SG160S Einbauanleitung

1. Safety Guidelines

1. Follow the installation instructions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the appli-
cations detailed in these installation instructions. Any
other use will not be considered to comply with require-
ments and would invalidate the warranty.
4. Please take note that any assembly, commissioning,
servicing and adjustment work may only be carried out by
authorized persons.
5. Immediately rectify any malfunctions which may influence
safety.

2. Description of function

2.1. SG160S
Safety groups of this type combine check valve, shutoff
valves, test point and diaphragm type safety valves in one
appliance. Flow first passes through the check valve and this
flow holds the valve disc in the open position against the force
of a spring.
The downstream safety valve is a direct operating safety
valve. That is, the opening force operates against the force of
a spring.
The shutoff valves enable the check valve to be checked and
serviced.
2.2. SG160SD
Safety groups of this type combine pressure reducing valve,
check valve, shutoff valves, test point and diaphragm type
safety valves in one appliance.
Flow first passes through the pressure reducing valve which
operates on a force equalising system whereby the force of a
diaphragm operates against the force of an adjustment
spring. The inlet pressure has no influence on either opening
or closing of the valve and therefore inlet pressure fluctua-
tions have no influence on the outlet pressure. The check
valve has a movable valve disc which pushes against a spring
when flow occurs.
The downstream safety valve is a direct operating safety
valve. That is, the opening force operates against the force of
a spring.
The shutoff valves enable the check valve to be checked and
serviced.
