Inquiry (采购产品): Vaccum check valves We are looking for disposable vacuum checkvalves to independently maintain vacuum to 1 Inch Hg (abs)in multiple process vessels, evacuated from a central articulated vacuum pump system. In order to succesfully isolate process pressure in each vessel from evacuation pressure fluctuations in other vessels we need the checkvalve to operate with a cracking pressure of below 1 inch Hg and also give reliable leakfree operation when the vessel is disconnected from the vacuum source. 2 Applications: (1) Clean air vacuum: Valves may be multiple use ; higher quality and vacuum reliability; (2)Epoxy resin infusion contamination: need to be low cost to allow disposal after each process cycle to prevent cost of cleaning. Application: resin infusion in aerospace composite manufacture **** Hidden Message ***** Jerry Kops 153 Keys Road Moorabbin3930 AUS Company: Marand Precision Engineering Title: Project manager Phone: +61 3 8552 0742 E-mail: j_kops@marand.com.au **** Hidden Message ***** j_kops@marand.com.au
