Frequently Asked Questions
Dual plate valves like the F16 series are more compact, offer lower pressure drops, and significantly reduce water hammer compared to traditional swing check valves.
For high-temperature or chemically aggressive environments, Viton is generally recommended over NBR or EPDM due to its superior thermal stability.
Yes, the dual plate design is highly effective in both horizontal and vertical installations, provided the flow direction is correct.
The body is available in Cast Iron (ASTM A126CL.B/GG25) and Ductile Cast Iron (ASTM A536/GGG40) to suit different pressure ratings.
Sizing depends on your pipeline diameter and flow velocity. Please refer to our Dimensions List (from 50mm to 1200mm) or contact our engineers for a calculation.
Nickel plating provides an additional layer of corrosion resistance, extending the life of the disc in mildly corrosive fluid environments.
