Firesafe ball valve range
April 2008
Valves, Actuators & Pump Control
Spirax Sarco has developed a wide range of fire safe ball valves to meet the standards of the hydrocarbon process industries requiring tight shut-off valves for isolation of processes in hazardous areas.
Available certification includes API Spec 6FA second edition, API standard 607 fourth edition, BS 6755: Part 2, ISO 9001/2000, European Pressure Equipment Directive 97/23/EC and ATEX approval.
Main applications include petrochemical plants, hazardous gases, refineries/hydrocarbons, chemical industries, water lines in fire network systems, natural gas pipes and solvent extraction (edible oil industry).
User benefits include tight shut-off (VI class) achieved by proper sealing methods and tolerances, safety - blowout-proof stems, essential on fire safe valves, and special secondary metal seats machined on the valve body providing a secondary seal in case of destruction of the main soft seats.
Additional benefits include low operating torque at high pressures resulting in smooth operation with no sticking and a graphite stem 'O' ring to avoid leaks to the environment, and even against fire.
