• Leak-free pilot
• On-off opening, fully open or closed (limited maintenance)
• Perfect tightness (no production loss)
• Perfect operation even with capacities smaller than those rated with all kinds of fluids
• Excellent repeatability and reliability
• Adjustable blowdown
• No pressure/flow limit
• With additional equipment (solenoid valve) the safety relief valve can be used as a discharge valve

To meet the most varied requirement, RSBD selects the appropriate pilot detector for the safety relief valve required (semi or full nozzle, metal / metal seats - soft seat with bellows, piston etc..).
