Product Overview

It has multiple control functions, which can prevent cavitation, eliminate turbulent flow, avoid vibration, and resist sediment. Thus, it is widely used in large-scale water supply projects to regulate the flow rate and flow pattern of pipeline media, as well as the pressure of the pipe network.

Main Features

• Has multiple control functions, capable of preventing cavitation, eliminating turbulent flow, avoiding vibration and resisting sediment.
• Is widely applied in large-scale water supply projects.
• Can regulate the flow rate, flow pattern of pipeline media and the pressure of the pipe network.

Working Principle

The working principle of the LHS941X Flow and Pressure Regulating Valve is as follows: It adjusts the opening degree of its internal valve core based on the preset or real-time changes in pipeline media parameters (such as flow rate and pressure). This adjustment controls the flow area of the medium passing through the valve, thereby regulating the flow rate and flow pattern of the pipeline medium, and maintaining the pipe network pressure within the required range. Meanwhile, its structural design helps prevent cavitation, eliminate turbulent flow, avoid vibration, and resist the impact of sediment, ensuring stable operation.

Structural Features

• Adopts a core structure that enables flexible adjustment of opening degree, supporting precise control of medium flow area.
• Integrates anti-cavitation and anti-turbulent flow designs in key flow passages to reduce fluid disturbance and equipment damage.
• Has a sediment-resistant structure (e.g., wear-resistant valve internals, smooth flow passages) to adapt to water supply media containing sediment.
• Features a stable overall structure that suppresses vibration during operation, ensuring long-term reliable use in large-scale 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
