DP SERIES
With its special O-Port gate design, the DP model is suitable for the most difficult applications involving solids. Due to its unique design, it can easily cut through a medium column holding solids. The integrated transverse seal sets the DP model apart from conventional O-Port gate valves, guaranteeing maximum performance and zero leakage.
