Product Description

Gas Pressure Regulator HON 300.

• direct acting gas pressure regulator, for systems in accordance with DVGW working instruction G 491 (A) and G 600 (A) (TRGI)
• especially suitable for dynamic regulating lines (e.g. gas furnaces, burner switching, gas engine operation)
• can also be used as a component for gas appliances according to EC Directive (90/396/EEC)
• suitable for gases in accordance with DVGW Worksheet G 260 and neutral, non-aggressive gases; other gases on request

• version with integral overpressure protection (IS)
• gas pressure regulator with incorporated safety shut-off valve (SSV) – optional designs with limited relief valve (SRV) or with safety diaphragm
• large inlet pressure range
• installation of different valve seat diameters is possible
• easy to maintain, thanks to interchangeable functional units (plug-in modules)
• SSV optionally in function class A or B, pressure equalizing valve (inner by-pass) integrated in final control element

Versions (options)
• without SSV
• SSV with manual release
• SSV with electromagnetic remote release
• with position indicator “SSV closed” (inductive proximity switch)
• regulating assembly with safety relief valve (pd up to 0.8 bar) or safety diaphragm
• with vent valve HON 915 (SSV/RA) or tripping valve HON 919 (SSV)

The direct acting HON 300 gas pressure regulator unit is used to maintain the outlet pressure at a constant level independent of inlet pressure variation or load. The unit comprises of regulator and integral SSV housed in one body.

After loosening the fastening screws the regulator and SSV cartridges can easily be removed from the body which can remain in situ for visual inspection during scheduled maintenance. If there is a defect, it is possible to exchange the functional units quickly with tested replacement units and to carry out the necessary maintenance work in the repair shop instead of at site.

The final contact element of the regulating assembly can be equipped with different valve seat diameters.
The valve seat versions are pressure compensated. The regulating assembly can optionally be equipped with a limited relief valve or a safety diaphragm. Both regulator and SSV are ICL (Internal Control Line) type on example shown.

The main valve body has measuring line holes to enable an internal measuring impulse connection for the regulating assembly and SSV. When external measuring lines are used, the internal connections are sealed by pushing balls into the holes.
The measuring diaphragm of the regulating assembly detects the actual outlet pressure and compares it to the setpoint value provided by the setpoint spring. Whenever the comparison reveals a deviation, the valve stem will act directly on the main valve position, thus changing the flow rate and adjusting the outlet pressure to match the reference value again.

At zero flow the regulator valves seals tightly as the outlet pressure rises slightly to lock-up pressure. If the outlet pressure reaches either the upper or lower preset limit, then the SSV will slam shut cutting off the supply pressure to the regulator.

The SSV measuring diaphragm and switch bush will move into the corresponding release position and the ball engaging mechanism will release the SSV valve stem, and the SSV control element will close by virtue of the closing spring. Ensure outlet pressure is returned to normal operating pressure (or the corresponding specified re-engage differentials for overpressure and under pressure) before attempting to latch open the SSV. The SSV can optionally also be equipped with a manual and a remote release. It can also be optionally designed for function class A (with diaphragm failure protection) or B (without diaphragm failure protection).
