Subject: automatic pumping spring valves the machine is fitted with automatic pumping spring valves; the load isdefined according to the type of valve and the characteristics of the product. This means that if the machine has been stopped or is inactive, and the feeding line is open and under pressure, you are able to check the flow of product through the machine. To make sure there is no product flowing through the machine when the machine is inactive, the user must provide a cutoff valve for the feeding line upstream the machine. что такое automatic pumping spring valves? спасибо:)) |
