SG150D

Safety group with interchangeable safety valve insert and pressure reducing valve

Product specification sheet

Construction

The safety group comprises:

•Housing with test socket G 1/4"

•Connections (versions AA, AB and AC)

•Shutoff valve

•Complete pressure reducing valve with fine 0.16 mm mesh filter and transparent filter bowl

•Check valve cartridge

•Approved safety valve exchange insert

•Drain connector

•Insulation shells

•Pressure gauge optional

Materials

•Dezincification resistant brass housing

•Brass threaded connections

•Stainless steel filter mesh on pressure reducing valve

•Transparent synthetic material filter bowl on pressure reducing valve

•High grade synthetic material pressure reducing valve insert, spring bonnet with adjuster knob, shutoff valves, test socket, check valve, safety valve insert and drain connector

•Fibre-reinforced NBR diaphragm

•NBR seals

•EPP insulation shells

Application

Safety groups of this type are used to protect pressurised water heaters according to the requirements of DIN 4753, Part 1, DIN 1988 and DIN EN1488.

They are compact appliances which incorporate all the necessary safety devices such as check valve, shutoff valve, test point, diaphragm type safety valve and pressure reducing valve in one unit.

The safety valve protects the downstream cylinder, pressure vessel etc. by automatically opening when excess pressure occurs. The check valve prevents back pressure, backflow and back syphonage of water from the hot water unit.

In addition, a balanced seat pressure reducing valve is fitted on the inlet to control the supply pressure to that required for the system.

Special Features

•DVGW-approval requested

•Fully approved for noise level protection to class 1

•Replacement insert tested to TRD 721

•Pressure reducing valve with inlet pressure balancing - inlet pressure fluctuation does not influence the outlet pressure

•Easy venting

•Meets KTW recommendations for potable water

Range of Application

For closed hot water storage units up to 200 litres according to DIN 4753 Part 1 and DIN 1988. Tested to TRD 721 for 1.0 to 10.0 bar pressure range.

SG150D Safety group with interchangeable safety valve insert

Method of Operation

Safety groups of this type combine pressure reducing valve, check valve, shutoff valve, 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 fluctuations 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 valve enable the check valve to be checked and serviced.
