Web2 jun. 2024 · In general, optimal piping system designs follow three basic principles: There must be a 5-10x nominal pipe size (NPS) of straight pipe on either side of the valve, i.e., both the upstream and the downstream sides of the valve. The minimum pressure to open a check valve is referred to as the cracking pressure. WebInsertion meters are very cost effective relative to pipe size, especially in 4" or larger pipes. This is because two sizes of insertion sensors can cover from 2" to 48" pipes. These meters are also very easy to install.
