Features

The shut-off valve uses a self-owned micro power unit to supply high pressure hydraulic oil, while the traditional power pump station and solenoid valve cabinet needn't be equipped.
The electro-hydraulic single acting shut-off valve uses a hydraulic transmission system and features a steady performance, low energy consumption and low noise levels, thanks to the pinion and rack transmission system.
The shut-off valve uses butterfly springs, which can achieve a larger driving force when closing and reduce the closing time of valves.
The emergency valve block can be coordinated with an emergency hand pump to conduct emergency operation to valves when power failures occur.
The shut-off valve uses a modular and integrated design, functions can be freely customized according to customer needs.
The main body of the shut-off valve is designed with a sectional structure, meaning the seals for the oil tank can be directly changed, which makes maintenance easy.
It is equipped with a manual operating device, which is independent of the hydraulic system and can conduct emergency operations.
