NO ACTUATORS, PILOTS OR INSTRUMENTS NEEDED
The Hydrocore™ Symmetrical pressure relief valve prevents the rising of the pipeline pressure 'Pu' above a preset level. The line fluid pressure powers the valve with no need for external actuators, pilots, instruments or an external power source.
The Hydrocore™ pressure relief 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.
The pressure relief set-point is adjustable by adding or removing spring washers. Adding spring washers increases the pressure relief set-point and vice versa.
