Features & Benefits
Zero Dead Volume
Valve seat is machined flush with the tank interior floor, eliminating the dead volume common with standard nozzle valves -- ensuring 100% drainage and preventing product accumulation, degradation, and batch cross-contamination.
Complete Tank Drainage
Flush seat design allows the tank to drain completely by gravity or pump suction without tilting or manual scraping -- essential for high-value pharmaceutical batches and viscous chemical products.
Sanitary Surface Finish
Mirror-finish electropolished surface (Ra <= 0.4 or 0.25 microns) eliminates microscopic crevices where bacteria could adhere, meeting 3-A Sanitary Standards and EHEDG guidelines for sterile and aseptic applications.
CIP / SIP Compatible
Valve is fully compatible with Clean-in-Place (CIP) and Steam-in-Place (SIP) procedures -- spray balls and steam can reach all wetted surfaces including the flush seat, ensuring complete sterilisation without disassembly.
Pneumatic Actuator for Automated Discharge
Spring-return or double-acting pneumatic actuator enables automated batch discharge integrated with process control systems, eliminating manual operation and ensuring consistent discharge timing.
Replaceable Seat Insert
Seat ring is replaceable in-line without removing the valve from the tank, reducing maintenance downtime and extending valve life in abrasive or high-cycle service.
