These are used to regulate the incoming pressure on a gas train for appliances utilising gas from Gas Families 1, 2 and 3. Our governors can be used with Air and other non corrosive gases within their pressure range and are suitable for both atmospheric and pressure jet burners including mixed or dual fuel burners as well as for industrial gas distribution.
