Product Overview

It is installed on the pipelines of high-rise building water supply systems and other water supply systems to reduce the higher upstream pressure to the required downstream working pressure. It features reliable pressure reduction effect, convenient adjustment and operation, and good energy-saving performance.

Main Features

• Designed for high-rise building and other water supply systems.
• Reduces high upstream pressure to required downstream pressure stably.
• Features reliable pressure reduction, easy adjustment and good energy efficiency.
• Adopts diaphragm structure for stable and accurate pressure control.

Working Principle

1. When the downstream pressure is lower than the set value, the diaphragm is pushed up, opening the valve core to allow more medium to flow through and increase the downstream pressure.

2. When the downstream pressure reaches the set value, the diaphragm is pressed down by the pressure, closing the valve core slightly to stabilize the downstream pressure at the required level.

3. The pressure can be adjusted by turning the adjusting bolt to change the compression force of the spring, thus meeting different downstream pressure requirements.

Structural Features

• Adopts a diaphragm-type structure, which ensures sensitive response to pressure changes for accurate control.
• Equipped with an adjustable bolt, facilitating easy setting and modification of downstream pressure.
• Integrates a valve core and spring assembly to stably maintain the set pressure.
• Has a compact overall design, suitable for installation in various pipeline layouts of water supply systems.

Maintenance

• Check hydraulic oil level annually
• Test closing time every 6 months
• Inspect disc and seat for wear during system shutdowns
• Lubricate adjustment mechanism yearly
• Verify proper operation after system pressure changes
