Globe valves made by Tyco Valves and Controls will enable Conoco to keep some processes at its Humber refinery operational during the maintenance of control valves.

The high-integrity Descote valves have been installed as bypasses on several processes, including boiler feed water and light hydrocarbons.

The manually operated valves have been designed to match the performance of the control valve, so they are highly reliable for controlling the flow while the control valve is out of service.

Descote valves are among the few manually operated valves on the market which are able to match the same control characteristics as control valves, without any vibration, stem shear or wire draw.

In the past refinery operators would either have had to install a further control valve to act as the bypass valve, which would be very expensive, or shut down the process during maintenance periods, with obvious financial implications.

Conoco also preferred the Descote valve because of its low maintenance requirements and because its design minimises the possibility of leakage.

The company is a leading integrated international energy company which is active in more than 40 countries and employs about 16,000 people worldwide.

The Humber refinery produces a wide range of petroleum products including petrol, diesel and petroleum coke.
