PRINCIPLES OF OPERATION
The Hydrocore™ excess flow shutdown valve is used for pipeline safety isolation when excess flow occurs. The valve closes when a preset differential pressure (ΔP=PU-PD) exists across the valve.
features and benefits
LOW TORQUE, LOW CLOSING FORCES
The Hydrocore™ excess flow shutdown valve is hydro-statically balanced, requiring very low operating torque or operating forces at all valve positions and for all valve sizes and all pressure ratings.
No gearbox is required to assist in the valve's opening and closing for the Hydrocore™ excess flow shutdown valve. The valve is
hydro-statically balanced and requires very low operating forces. The Hydrocore™ excess flow shutdown valve derives its actuating power directly from the line fluid pressure.
The Hydrocore™ excess flow shutdown valve is simple and reliable with a robust construction. Very little maintenance is required, it can be undertaken by semi-skilled personnel and with a short downtime period.
Seat Leakage - B16.104 class III, IV, V or VI, depends on valve type and application.
