Product Overview

This valve is installed at the outlet of the water pump. It functions to restrict the flow when a single pump starts up and during the operation of multiple pumps. It prevents the motor from overloading when the water pump operates under conditions of low head, high flow, and low efficiency, while also achieving a certain energy-saving effect.

Main Features

• Installed at the water pump outlet, mainly used for flow restriction and check.
• Prevents motor overload caused by the pump’s low head, high flow and low efficiency.
• Reduces energy consumption while ensuring stable pump operation.
• Suitable for both single-pump startup and multi-pump operation scenarios.

Working Principle

1. When the pump starts, the valve controls the flow rate to prevent excessive flow that may cause motor overload.

2. During operation, it automatically adjusts according to the pump’s head and flow conditions, maintaining efficient operation.

3. It also acts as a check valve to prevent reverse flow of fluid when the pump stops or in abnormal conditions.

Structural Features

• Adopts an integrated structure design for easy installation and maintenance at the pump outlet.
• Equipped with a flow-control component to adjust flow stably based on working conditions.
• Includes a non-return mechanism (e.g., check disc) to block reverse fluid flow effectively.
• Has a robust body structure that withstands the pressure of pump operation.

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
