Gate valve manual gearbox

GATE VALVES | Gate valves are designed to close off or open up the flow in a pipeline. The wedge is designed to completely stop flow and form a tight seal against pressure in either direction. In the open position, the wedge is completely out of the flow stream. Gate valves are not recommended for throttling use. Install Pow-R-Seal Gate Valves into the line with the preferred pressure flange end or weld end (marked with red paint from the factory) as the upstream side. When handling or installing the valve, keep the valve in the full open position whenever possible to prevent foreign matter damage to the gate and seat sealing surfaces.  · In this design, when override is needed, the gearbox rotates until it engages with the key then rotates back to operate the valve. The third design utilizes planetary gears, which allow input from an actuator or manual means to rotate the valve without engaging or .
