Erosion & Wear Resistance  (Key to long service life under severe conditions)

● Solid sintered Carbide Disc & Seat:

  Engineered with solid sintered carbide construction for exceptional erosion resistance, high hardness (≥85 HRA), and superior corrosion protection.  

● Hardened Flow Path: 

  Features either flame-sprayed hardening or full carbide liner for sustained integrity.  

● Self-rotating and self milling trim:

  Rotating mechanism continuously mills sealing surfaces, a good compensating for wear.  

● Scraper design:  

 Scraper design prevents particle entering sealing surface.  

● Sliding Motion:

  Disc is parallel to seat, eliminating high-impact erosion from sudden flow re-direction.  

Preventing Buildup Prevents Jams

● Open valve pocket Design:

  Maximizes media flow-through.  

● Standard Purge port design:  

  End user can design purging system to avid solid medium accumulation by purge port.
