The Manual Bottom Discharge Valve is designed for safe and efficient discharge of liquids, slurries, and process media from reactors, tanks, and vessels. Operated by a handwheel, it offers precise control, excellent sealing performance, and minimal residue retention. Its robust construction ensures reliable operation in demanding industrial environments.

Manual bottom discharge valve

The Manual Bottom Discharge Valve is installed at the bottom outlet of storage tanks, reactors, and process vessels to ensure complete media discharge and reliable shut-off. The valve is designed to minimize dead zones, prevent material accumulation, and improve process efficiency.

Manufactured from high-quality stainless steel, carbon steel, alloy steel, or special corrosion-resistant materials, the valve is suitable for handling liquids, viscous fluids, slurries, and chemical media. Manual handwheel operation provides easy control and dependable performance without external power requirements.
