Valves for transmission mains and distribution networks
Transmission mains, distribution networks and valve chambers. Isolation, non-return and air management for pipelines that run for kilometres.
Along the line
The valves this kind of line usually carries, and what each one is there to do.
Dual-plate check valveStops reverse flow at the pump discharge.Gate valveIsolates a main or a branch, with a clear bore when open.Butterfly valveIsolation on larger mains, where a gate valve grows tall and heavy.Air valveReleases air at high points and admits air when the line drains.Pressure reducing valveHolds the downstream pressure where the network drops to a lower zone.Eccentric semi-ball valveIsolation on water transfer and distribution lines.Y strainerCatches debris ahead of meters and control valves.
