Thin Wafer Check SS316 Complete: THINSS

• • What It Is

    • It’s a thin wafer check valve (sometimes called a “wafer-flap” valve) from SANSPAR’s Uni-Flo line. SANSPAR+2SANSPAR+2

    • It’s rated for PN16 (i.e., the nominal pressure rating is 16 bar). SANSPAR+2SANSPAR+2

    • The “SS316 Complete” means the body and the disc (flap) are made of 316 stainless steel, not just a coating — this gives good corrosion resistance. SANSPAR+1
