Inquiry (采购产品): vacuum check valves I am interested in price and availability of 4" flanged 150# class vacuum swing check valves for gasoline vapor service. Material should be forged or stainless steel. Forged steel requires stainless steel seat due to rust potential. Do you have product info you could email or fax to me? I have a very old product brochure from a previous purchase. Thanks. **** Hidden Message ***** Rod Beals 30066 USA Company: Chevronn Products Phone: 770-984-3134 E-mail: abea@chevron.com **** Hidden Message ***** abea@chevron.com
