ZLQ Series Axial Flow Gas Shut-off Valve

ZLQ Series Axial Flow Gas Shut-off Valve

Overview

ZLQ Series Axial Flow Gas Shut-off Valve is an automatic shut-off safety device installed at pressure regulating stations or gas distribution pipelines. When the downstream pressure reaches the preset shut-off pressure of the valve, it can quickly cut off the gas supply (manual reset required).

This product is applicable to various working conditions such as city gate stations, regional pressure regulating stations, large and medium-sized public users and industrial users.

Applicable Media

Non-corrosive gases such as natural gas, town gas, liquefied petroleum gas, air and nitrogen.

Product Features

Axial flow structure with high flow capacity.

Sleeve valve structure; no external bypass facilities required for resetting, simple operation.

Protective sealing gasket for long service life.

Shut-off accuracy up to 1%, capable of overpressure and under-pressure shut-off.

Fast response with response time ≤ 1 s.

Functions such as remote shut-off and shut-off alarm can be expanded.
