Over the past several years H & G have been involved extensively in the assembly and production of these products.

Using Technolog, Elster & Donkin equipment we have assembled and tested each product to ensure compliance to GIS standards and produced test certification for each item to ensure traceability in line with our 1SO900 I approval.

The addition of a snubber enables a reservoir of Gas to supply a smooth flow of Gas thus giving a more accurate reading of pressures in the system.

Pilot valves are assembled using approved fittings and techniques familiar to the Gas Industry and all items are leak tested prior to delivery, each item is then recorded and certified.

We carry a full range of Valves, fitting's, filters & tube that are used in the manufacture of the Profile Boards and Pilot valves.
