RTZ-15/0.4 Medium Pressure Inlet Pre-meter Gas Regulator
Get In Touch →Product Features
This pressure regulator is specially developed for medium‑pressure household gas supply in cities. Its design and manufacturing draw on foreign prototypes and structural principles, and it is developed through elaborate design by our factory’s technical personnel.This regulator is mainly used for pressure stabilization and regulation in urban transmission and distribution pipelines for natural gas, manufactured gas, liquefied petroleum gas, mine gas, biogas, straw‑based gas and other gases.

Common Faults and Troubleshooting Methods
Sudden gas cut‑off: Check whether the spring is broken or the valve pad is deformed; replace them if necessary.
Excessive shut‑off pressure: Check for foreign matters trapped at the valve port and clean it.
Excessively high or low outlet pressure: Check whether the spring is deformed or damaged; repair or replace it as required.
