Waterworks Valves for Municipal Water Supply
Waterworks valves for municipal water supply: gate, butterfly, check, hydraulic control and air valves from DN15 to DN1200. This page sorts the range by what the valve does on the network — isolate a main, guard a meter chamber, stop backflow at a pump, hold a pressure zone, or let air out at a high point. Sizes, pressure classes and standards below are read from the product data, and each card opens the full parameter tables for its lead model.

What we need to quote
A pump or a lined valve is quoted against the duty point, not off a catalogue page. Send these and the reply is a model with its curve, not a range.
- 01Line size and pressure class — DN40 – DN1200, PN10 / PN16
- 02Duty — isolation, pump discharge, level or pressure control, air release
- 03Standard the network is specified to — BS5163, DIN 3352 F4 / F5, AWWA C509 / C515 or GB
- 04Buried or chambered, and whether the valve needs an electric actuator or a lock head
