Inquiry (采购产品): Chain Valves Hello, I am writing you to inquire about a visual indicator to show whether the valve is open or closed on your chain wheel valve operator (Model C9 A)? We are looking for something that would make it easier to tell what position the valve is in. Your help on this matter is appreciated.
