VALVOLC Self Holding Electric Ball Valve

Product application:

VALVOLC electric ball valve is specially designed for controlling the technical water supply system, main valve bypass circuit, and oil circuit of hydropower stationsValves. Compared with traditional solenoid valves, it has the advantage of zero pressure differential opening, and does not get stuck, blocked, or leak. The valve can be opened and closedIn place power outage automatically maintains the current position, without burning the electric head due to long-term electrification.

Product features:

1. Adopting a ball valve structure, it has a large flow capacity, low pressure loss, and can be used in both forward and reverse directions.

2. Adopting a hard sealing structure, the sealing performance is better, and the valve core will not get stuck or leak due to mud and sand.

3. Fully imported electric mechanism with dual protection against overheating and overload.

4. Provide on-site valve position indication for easy maintenance. Provide signals for fully open and fully closed valve positions to facilitate monitoring of the systemTime monitoring.

5. The electric drive mechanism comes with a manual mechanism, which allows the operator to manually turn it on even if the power supply disappearsClose the valve, it is safe

Guarantee.

6. Adopting stainless steel valve core, it will never corrode. The starting range of zero pressure difference and up to 6.4MPa pressure difference,Adapt to the oil, water, and gas system of the power station

Used in various occasions.

7. This valve performs excellently in oil systems, brake systems, and sealing water systems.
