Description
WCV1, WCV2 and WCV3
Wafer Check Valves
WCV1, WCV2 and WCV3 wafer check valves are designed to be sandwiched between flanges. They are specifically designed for use on
applications where there is a high proportion of particles in the liquid e.g.: sewage, paper mills, sludges etc. The standard seating ring is EPDM.
Sealing ring options : Viton - suffix 'V', PTFE - suffix 'T' and NBR - suffix 'P'.
Standards : Designed and manufactured in accordance with DIN 3202 Part 3.
Certification : These products are available with a Typical Test Report.
Certification to EN 10204 3.1 is also available on request.
Note: All certification / inspection requirements must be stated at the
time of order placement.
Sizes and pipe connections
