Electric piston type flow and pressure regulating valve

The function of electric piston type flow and pressure regulating valve

LHS941X electric piston type flow and pressure regulating valve is used for water systems that require regulating pipeline flow or pressure, and achieves working condition control by changing the internal throttling area. The current page parameter is DN50-DN2000, which includes different standard configurations such as PN16, Class150, and 10K.

Why is it necessary to provide flow rate and pressure difference for selection?

The selection of flow and pressure regulating valves cannot be based solely on pipe diameter. It is necessary to provide design flow rate, pre valve pressure, post valve pressure, allowable pressure difference, medium temperature, and control objectives. High pressure differential conditions also require evaluation of flow rate, noise, and cavitation risks in conjunction with actual product design.

Different export conditions need to be checked separately

The control objectives of water supply, water conveyance, water storage or discharge systems are different, and the valve size, control mode and actuator should be determined according to the system operating conditions. It cannot be uniformly declared that all operating conditions are 'free from vibration, cavitation, noise, or damage to pipelines'.

Electric control configuration

The power supply, switch or adjustment mode, input/output signals, feedback and communication functions of the actuator should be determined according to the project control system and should not be used as the default configuration for all LHS941X products.

Frequently Asked Questions

Can flow and pressure regulating valves completely eliminate cavitation?

We cannot guarantee this. Whether cavitation occurs is related to pressure difference, flow rate, temperature, and internal flow channel design of the valve, and needs to be verified according to specific operating conditions.

Do you only know if DN caliber can be selected?

Not enough, data such as flow rate, pre valve pressure, post valve pressure, temperature, and control requirements need to be designed.

Are PN16, Class150, and 10K the same pressure level?

It is not the same standard system, and should be confirmed separately according to the actual design and flange standards adopted.
