r2 Series is a full lift, full-nozzle pressure safety valve featuring both fixed and adjustable blowdown rings. This series is designed for easy and simple maintenance, thanks to its new design, which consists of three main parts: a separate cap and bonnet. Both investment casting and forged materials are used in the design, enhancing durability and performance.
The r2 Series is engineered to cover a wider range of pressures compared to the r1 Series and is available with various accessories to meet diverse application needs.
Features and Benefits
• Simplified maintenance:
separate parts in bar material (forged) design leads to an easy maintenance.
• Interchangeable parts:
Valves can easily be modified from gas to liquid or liquid to gas with the minimum number of parts.
• Wide pressure range:
r2 series are specially designed to implement in high pressure (up to 350 bar) process conditions.
• Material selection:
A wide range of materials are offered, including non-ferrous for low temperature and oxygen service, and exotic alloys specified for the chemical and process industries.
• High performance springs:
Safety relief valve springs are specially designed to guarantee set point repeatability.
• Guiding surfaces:
The material selection of guiding components, together with self-aligning disc pivot points, ensures correct alignment and no galling of guiding surfaces.
• Trim:
r2 Series valves have been designed with PMSS (Primary Metal Secondary Soft) trim to give optimum performance in various process conditions.
