Gas pressure regulators are designed to regulate the pressure of natural gas for the connection of gas sampling devices to public, domestic and industrial distribution with the highest input pressure up to 0.5 MPa.
The two type series of regulators produced under the designation RTP..-M and RTP..-D belong to the so-called opening direct-acting regulators with two-stage regulation, which use the gas flowing through the pipeline as a power source for regulation without the aid of any external power source. These regulators do not continuously release gas into the atmosphere, but occasionally there may be a release of gas from safety devices. They regulate the gas pressure in two stages, i.e. the inlet pressure is pre-regulated in the first stage of regulation, it is further regulated in the second stage, they are integrated into one body of the regulator. The interaction of both stages of regulation creates a device that maintains the value of the regulated variable (output pressure of the heating gas) in the required tolerance field, regardless of the disturbance variables of the variable (change in inlet pressure or change in volume flow). Regulators are set to an output pressure of 2 kPa by default, RTP..-D regulators can also be set to output pressures in the range of 5 kPa on request.
Both design series of regulators have other additional devices, such as a safety quick release and a safety valve, which are integrated into the body of the regulator.
