Ductile Iron Grooved Pressure Relief Sustaining Valve G500X-16Q

Product Description

The G500X grooved pressure relief sustaining valve is used in fire protection or other water supply systems to prevent system overpressure or maintain pressure in fire protection water supply systems. It also reduces water hammer impacts after the fire pump is shut off and is used in water hammer arresters for large-scale water supply systems. Valves in this series are widely used in water supply pipeline networks for high-rise buildings, residential areas, and other applications, as well as in urban water supply projects.

How It Works

The G500X grooved pressure relief sustaining valve consists of a main valve, relief and pressure-maintaining pilot needle valves, a ball valve, a strainer, and a pressure gauge, forming a hydraulically controlled piping system. Utilizing automatic hydraulic operation, it can function as both a relief valve and a pressure relief sustaining valve. When used as a relief valve, it maintains the pressure in the water supply line below a preset safety threshold; when used as a pressure-maintaining valve, it maintains the water pressure upstream of the main valve above a preset value, thereby sustaining the water supply pressure upstream of the main valve.

Scope of Application

Urban construction, chemical engineering, metallurgy, petroleum, pharmaceuticals, food, beverages, environmental protection, and other fields.

Product Features

This product utilizes self-acting hydraulic control, requires no additional devices or power sources, is easy to maintain, and serves multiple functions with a single valve.
