Manual-hydraulic flat plate valves are shut-off devices integrating dual operation modes of manual and hydraulic, widely applied in industries such as petroleum, natural gas, and chemical engineering. With parallel-sliding gate plates as the core components, under normal working conditions, these valves can achieve remote and automated operation through a hydraulic control system. The hydraulic power drives the valve stem, enabling the gate plates to open and close quickly and smoothly, precisely controlling the flow of fluids. When encountering malfunctions in the hydraulic system or special working conditions, the operation mode can be switched to manual. By turning the handwheel, the gate plates are driven by human force, ensuring the reliable operation of the valves.
These valves offer the advantage of dual operation guarantees. They not only enhance work efficiency and automation levels but also strengthen system stability and emergency response capabilities. Meanwhile, manual-hydraulic flat plate valves feature excellent sealing performance, effectively preventing medium leakage. Their robust structure allows them to withstand harsh conditions such as high pressure and strong corrosion, making them key equipment for ensuring the safe and stable operation of complex industrial processes.
