Inquiry (采购产品): 2 swing check valve We operate a vacuum autoclave that uses the gas Ethylene Oxide for sterilisation. After many years service the Pokorney 2" stainless steel swing check valve has failed. Can you offer a replacement, if so at what cost. **** Hidden Message ***** John Slater 1026 Company: Smith & Nephew E-mail: j.slater@smith-nephew.co.nz **** Hidden Message ***** j.slater@smith-nephew.co.nz
