• 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.
