Manual flat plate valves are commonly used shut-off devices in industries such as oil and natural gas, which are opened and closed by manual operation. With a parallel - sliding gate as the core component, these valves rotate the handwheel to drive the valve stem, moving the gate along the sealing surface of the valve seat to open and close the fluid passage.
They feature excellent sealing performance. The gate fits snugly against the valve seat, effectively preventing medium leakage. Moreover, they are easy to operate, eliminating the need for complex driving devices. This makes them particularly advantageous in on - site emergency handling or low - energy - consumption operation scenarios. Additionally, manual flat plate valves have a compact structure and are convenient for maintenance. Their wear - resistant and high - pressure - resistant properties ensure reliable operation even under harsh working conditions, making them essential valve equipment for ensuring the safe and stable operation of pipelines.
