Mod. GR6
Residential gas pressure regulators

Mod. GR6

The GR6 series  two-stage self-driven spring loaded regulators are widely used in both civil and industrial installations using natural gas, LPG and other non-corrosive gases.

They are designed either to be fitted directly  to a gas meter or used in general pipeline work. They can be mounted in any position provided they are protected from the weather.

A balanced two-stage regulator results in accurate regulation and high operational reliability with the possibility to use the same equipment to meet what the market currently requires  (low pressure) and  future needs (medium pressure) just changing the setpoint, to satisfy additional gas consumption with the same infrastructure, which means   safety devices must be adequate.
Where the installation is in an enclosed space , the internal relief vent can be piped to outside. Simple to install.

These regulators are manufactured according to UNE 60402-2 and approved for the Nof AENOR.

VS/AM 65 VS/AM 65 The VS/AM 65 relief valve is a safety device (SBV) which vents gas when the system pressure exceeds the set value due to temporary events such as expansion due to rise in gas temperature or downstream pressure shocks caused by sudden changes of flow rate etc.
