Inquiry (采购产品): Valves for Oxygen service Dear Sir Subject : Valves f or OXYZEN service We are setting up a Air separation Plant in India to produce OXYZEN. For this we require 2 nos control valves and 4 nos 200 NB Isolation valves , the specifications of which are enclosed herewith. we request you tpo please quote for these valves. You may select the material of various components to suit OXYZEN service from your vast experience. As you are aware these valves will require degreasing also With Best Regards B K Bansal AGM(Instrumentation) We want to attach MS Word File containing specifications Please let us have ypur e-mail address. However we are pasting the spec. sheet. We are afraid it may not be readable in this form. So please let us know your e-mail I D Tag nos.
