Hydrants & Valves

Alongside our Dry Riser Testing Services, we also offer an in-depth knowledge of valves, penstocks and actuators to suit specific customer needs across a range of products.

Our services extend to troubleshooting and site surveys, supply and installation and the manufacture of ancillary equipment.

The examples you will find on this page are just a flavour of the wide range of valves we can supply. Get in touch to find out more about these items, or for any enquiries about products not listed here.


Underground HydrantsUnderground hydrant

The Series 29/91 is the dimensional equivalent of a squat hydrant but with a full, straight bore from inlet to outlet. This allows a greatly enhanced flow-rate and ease of introduction and retrieval of pipe maintenance and measurement equipment. It is suitable for use with water and neutral liquids to a maximum temperature of +70°C. Complies with requirements of BS 750:2012 and BS EN1074-1:2000 and EN 14339:2005, underground hydrants. Also to BS EN 1074-6 for potable (drinking) water. Resistant to corrosion of other component parts. Resistant to disinfection products.

Undergorund hydrant 2The Series 29/388 is a squat fire hydrant suitable for use with water and neutral liquids, to a maximum temperature of 70°C. Complies with requirements of BS 750 and BS EN1074- 2:2004 and EN 14339:2005, underground hydrants. Also to BS EN 1074-6 for potable (drinking) water.

It is recommended that applications in a corrosive atmosphere or sited in exposed locations use a stainless steel stem 1.4404 (316) and all exposed fasteners in A4 stainless steel.
