Dump valves or flap best Companion for Air Locking & Feeding in Vacuum or Pressure Conditions When Dealing With Irregular Shapes DH Series Dump Valve or flap valves has been developed to provide the bulk-material handling industries with a low-cost versatile air locking solution to discharge bulk solids of irregular shapes or lumps while restricting the backflow of air.
Dump Valve or flap valves can be effectively used in either vacuum or pressurized conditions. These valves are designed with an emphasis on total sealing and continuous uninterrupted discharge for a long service life with minimal maintenance. Double dump valve works with two flaps assembled in a housing continually operating in an alternative fashion, while flap one is closed to collect the material and the second one is open to discharge the material.
The “labyrinth seals” ensures perfect sealing of rotating shaft thus ensures zero leakage through shaft ends. These labyrinth seals even effective with highly abrasive products and also when there is high pressure across the system.
DH Series Dump Valves are in Cast Iron construction as standard and available in opening sizes ranging from 150 mm to 350. Larger sizes can be fabricated as based on the application requirements. These valves are not only robust, rigid and durable but can also be customized to the specific requirements of a given application.
These valves can be operated on Gravity (without any power or external actuation) or using Pneumatic rams or Geared Motor.
DH Series Dump Valves are CE marked, ATEX Certified and in compliance with the provisions of all applicable Health & Safety Requirements across the globe.
