These service regulators adjust gas pressure from a maximum supply pressure of 500 mbar down to the service pressure required by a gas appliance. They are typically used in residential and commercial gas installations and are generally positioned upstream of the gas meter. They are suitable for natural gas, LPG, and other non-corrosive gases (such as air or nitrogen). A mesh filter is installed at the inlet connection.
Designed for either straight (STB27L) or right-angle (STB27R) installation.
Excellent pressure control: Thanks to a fully balanced seat design, the regulated pressure remains constant regardless of fluctuations in the supply pressure.
High capacity: Depending on the inlet pressure range and the required regulated pressure precision, these models can achieve flow rates of up to 12.5 (n)m³/h for natural gas and 15 kg/h for LPG.
Filter: A mesh filter is incorporated into the inlet connection on certain models.
Under-pressure shut-off (UPSO): Models are available with either automatic or manual reset functions for the UPSO feature.
For models with an automatic reset function, the typical reset gas flow rate is 6.4 liters per hour.
Please note that these products do not fall under the scope of the Pressure Equipment Directive (PED 2014/68/EU), as their maximum pressure is below 0.5 bar.
