HC500 Pressure Holding and Relief Valve

HC500 Pressure Sustaining/Relief Valve

Product Overview

The HC500 Pressure Sustaining/Relief Valve operates automatically using hydraulic power, functioning both as a relief valve and a pressure sustaining valve. As a relief valve, it maintains the water supply line pressure below a set safe value; as a pressure sustaining valve, it keeps the upstream water pressure above the set value, ensuring the upstream water supply pressure. It is widely used in high-rise buildings, residential areas, water supply network systems, and urban water supply projects.
