Product Overview
This valve features a relatively complete hydraulic system and electrical control system, allowing both on-site and remote operation. The control system of this valve uses an accumulator to replace the counterweight used in products from other domestic manufacturers. It converts the potential energy of the counterweight into fluid energy storage. This not only saves the energy consumed in supporting the heavy counterweight during long-term operation but also improves the pressure-holding performance of the hydraulic system, avoiding personal injury accidents and the psychological sense of insecurity and fear for maintenance personnel during operation. Its control mechanism has a novel concept and reasonable design, featuring small size, light weight, simple structure, complete functions, flexible and reliable action, and an attractive appearance. It is energy-saving and material-saving, convenient for maintenance, and does not require stopping the water pump during maintenance. It can easily achieve pump-valve interlocking program control and microcomputer centralized control. In case of a power failure, the valve can be closed by cranking the manual oil pump. Opening and closing the valve is very convenient.

Product Features

1. Can replace the pump outlet stop valve and check valve, integrating mechanical, electrical, and hydraulic systems into one, occupying a small footprint.

2. High degree of automation, capable of local, remote, and linkage control.

3. The electrical system can adopt a PLC intelligent control system or a conventional relay-type system.

4. The hydraulic system motor has low power, high working efficiency, good pressure-holding performance, and a long oil pump start interval.

5. The hydraulic system has an automatic pressure-holding function with a long pressure-holding time; the oil pump start interval can reach 500 hours.

6. Has a clear opening indicator and a mechanical limit adjustment mechanism. The limit switch device has a waterproof and dustproof design, is not exposed, and features stable performance and a long service life.

7. The electrical operation interface is user-friendly and diverse, available in standard push-button, text-based, or touch-screen designs. New human-machine interfaces can also be designed according to customer needs.
