Y-Type Flush Bottom Valve
Product Range
Y-Type Flush Bottom Valve
Flow-Tek Flush Bottom Tank Valves are engineered for complete and reliable discharge of materials from processing tanks. Their design ensures the outlet nozzle at the vessel wall is fully sealed, preventing solids from accumulating or solidifying in the nozzle neck. This guarantees smooth discharge, eliminates blockage, and avoids the retention of unreacted or residual material, ensuring optimal efficiency and consistent process performance.
Flush Bottom Tank Valves feature a modified Y-type body with an angle-style design, positioning the stem in the vertical branch for optimal operation. The seat and disc assembly mirrors a globe valve configuration with precise metal-to-metal seating. Depending on the application, the disc can either lift from the seat to open into the vessel or pull down from the seat to open into the valve, ensuring reliable and controlled material discharge.
All Flow-Tek valves are engineered and manufactured to international design standards, ensuring complete interchangeability, exceptional quality, and precision craftsmanship
Available Designs for Flush Bottom Valves
