Technical Data - Samson 44-7 Mounting And Operating Instructions

Design and principle of operation

3.1 Technical data

The regulator's nameplate contains informa-
tion on the regulator version (see sec-
tion 2.1).
Process medium and scope of application
The excess pressure valve and safety excess
pressure valve are designed to maintain the
pressure upstream of the regulator to the ad-
justed set point especially in district heating
systems and extended heating systems.
Type 44-4, Type 44-7 and Type 44-8 are
suitable for controlling liquids and gases.
− Max. permissible temperatures for gases
up to 80 °C
− Air/nitrogen up to 150 °C
− Liquids up to 150 °C
The regulator is closed when relieved of
pressure. It opens when the upstream pres-
sure rises above the adjusted set point.
Type test
The Type 44-4 and Type 44-8 Regulators
have been typetested as safety excess pres-
sure valves (SEV) by the German Technical
Inspectorate (TÜV).
The test mark is available on request.

Temperature range
The Type 44-4, Type 44-7 and Type 44-8
Regulators are designed for a temperature
range from 0 to +150 °C.
Leakage class
All regulators have the leakage class I
according to IEC 60534-4.
Noise emission
SAMSON is unable to make general state-
ments about noise emission as it depends on
the regulator version, plant facilities, process
medium and operating conditions.
Risk of hearing loss or deafness due to loud

noise.
Wear hearing protection when working near
the regulator.
Dimensions and weights
Table 4 provides a summary of the dimen-
sions and weights of the Type 44-4, Type 44-
7 and Type 44-8 Regulators. The lengths and
heights in the dimensional drawings are
shown on page 17 onwards.
