Description

Delta-Elektrogas R-125 Series Medium Pressure Regulators is a medium-pressure regulator for gas according to EN 334. It is available also with a safety shut-off valve which blocks gas flow in the event of a spike or drop in the outlet pressure, in accordance with EN 14382. This device is suitable for supplying gas at stable pressure to all the devices downstream and protecting them against excess of pressure.

R… type products are pressure regulators for gaseous media, suitable for all types of gas-consuming appliances.
R-125 models are high-pressure devices with an inlet pressure of 10 bar or 12.5 bar.
RS-125 is a regulator that integrates a safety shut-off valve.

In order to assure the safest working conditions, the shut-off valve and regulating member are totally independent.

Features

R series pressure regulators are direct-acting spring-loaded regulator type, controlled by a
diaphragm and spring. The balanced valve design ensures a constant pressure setting when
upstream pressure varies.
RS version is an R regulator with an integrated safety shut off device against abnormal outlet
pressure. Shut off valve system is independent from regulating device, to assure an high level of
safety.
Regulators are available with inlet/outlet connections from DN25 (1”) to DN50 (2”).
Regulators are manufactured in three different versions in relation with outlet pressure: LP (outlet 15-160 mbar), MP (outlet 150-400 mbar) and HP (outlet 400-4000mbar). In any version components are optimized to achieve the best performances. Maximum inlet pressure is equal to 10 bar for version LP and MP; 12.5 bar for version HP.
The body of regulators are made of spheroidal graphite cast iron and covers are made of aluminum cast alloys for suitable strength with pressure.
Regulators are equipped with adjustable springs, so that outlet pressure, over pressure and under pressure can be set on site in a very precise way.
Regulators are equipped with an internal pulse line. An additional external pulse line can be mounted to reach the best capacity performance.
Regulators have been designed to generate low pressure drop with high flow.
Sealings are made of NBR-based rubber.
Regulators are suitable for use with non-aggressive gases included in the 1, 2 and 3 families (EN 437).
All components are designed to withstand any mechanical, chemical and thermal condition occurring during typical service. Effective impregnation and surface treatments have been used to improve mechanical sturdiness, sealing and resistance to corrosion of the components.
