For large loads like factories, office buildings, restaurants, etc., Fisher has a variety of commercial/industrial regulators. Only the most popular commercial and industrial regulators are shown here. Other orifice sizes and outlet pressure ranges are available. The higher capacities on commercial and industrial installations usually require a two-stage regulator system.
Type 99 – Pilot-operated unit keeps outlet pressure constant despite varying flow rates and inlet pressures. The 99 can be used for low or high pressure. A downstream control line is required.
