Performance & Flow Design
- Full Open Flow Design: Water flow does not directly lift against the gate, reducing restriction and pressure loss
- Silent Closing Action: Spring-assisted plug prevents reverse flow shock and pump damage
- Heavy-Duty Convex Plug: Automatically locates and seals under all pressure conditions
- Cantilever Hung Plug: Ensures stable operation and long service life
- Anti Water Hammer Performance: Reduces noise and impact during pump shutdown
Unlike traditional swing check valves, the CHF silent check closes rapidly before reverse flow accelerates, preventing damaging pressure spikes and mechanical shock.
Sealing & Construction
- Seal Type: NBR U-Ring for tight soft sealing
- Spring: Stainless steel
- Plug / Seat / Retainer Materials: Brass or Stainless Steel (matched to body material)
- Bypass Valve: Brass or Stainless (DN50–DN150 only)
- Pin & Internal Components: Brass or Stainless Steel
The unique U-ring sealing design provides excellent tightness across low and high pressure conditions while maintaining long-term durability.
