Проблемные вопросы и пути их решения
1. Erosion: 
  Hard fluid erosion damages sealing surfaces.

2. Abrasive: 
  Solid particles can enter and damage the sealing surfaces.

3. Jamming:  
  Solid particles accumulate inside valve pocket, increase valve operating torque, resulting valve jamming and even cannot be operated.
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.
