RTZ-*/*FQ Series Gas Regulator

Product Application

RTZ‑*/*FQ type pressure regulators are suitable for pressure regulation and stabilization of natural gas, coal gas, liquefied petroleum gas, biogas and other non‑corrosive gases. They are new‑type regulators replacing balanced (self‑operated) regulators, and applied to pressure regulation for residential communities, small public users, gas‑fired boilers, etc.

Product Features

1.FQ series pressure regulators adopt modular structure design with built‑in signal pipes. They feature stable performance, large flow capacity, low cost and compact structure, and support convenient on‑line maintenance.

2.Automatic over‑pressure shut‑off.

3.For main structure and dimensions of FQ series pressure regulators, refer to Figure 1.

4.This regulator can also be configured into integrated boxes, cabinets and skids integrating pressure regulation, metering and other functions.
