❓ Frequently Asked Questions
What are the primary applications for this wafer check valve?
These valves are widely used in ballast and bilge systems, chemical processing, desalination plants, drinking water systems, food and beverage industries, HVAC, mining, and wastewater treatment.
What pressure ratings do you offer for these valves?
Our standard offerings include 10 Bar and 16 Bar working pressures, with shell tests up to 24 Bar and seal tests up to 18 Bar.
Can the valve be installed in vertical pipelines?
Yes, due to its superior tightness and self-aligning conical seating, the valve can be used in vertical piping with an upward flow.
What materials are available for the valve body and seat?
Body materials include Cast Iron, Ductile Iron, Carbon Steel, and Stainless Steel. Seats can be customized with BUNA, NBR, EPDM, Neoprene, or Viton depending on the medium.
Does the valve design help prevent water hammer?
Yes, the disc pivots through a small arc which allows for rapid closing, effectively preventing backflow and minimizing "water hammer" effects.
Which international standards do your products comply with?
Our check valves are designed and tested according to EN12334, API594, ISO5208, and ANSI B16.1, among other major global standards.
