Redutor de Pressão SGV-02R

Product Description

SGV-02R N/M is a compact positive pressure reducer for Compressed Natural Gas (CNG), which combines both reduction pressure principles, the piston and membrane systems. It is designed for sequential gas injection systems, which requires to maintain constant pressure at different flow rates required by the engine.

It has integrated input gas filter together with the solenoid valve and internal over pressure safety valve, also includes an entry for compensating the output pressure by the vacuum to keep stable output pressure in reference to the intake manifold. The output pressure can be regulated from 1 to 2.5 bar (100 to 250 Kpa).

It is necessary to connect the hot water inputs for optimal working condition and ensure correct and stable gas output pressure in all engine conditions.
