Descriptions

• Safety relief valve springs are specially designed and manufactured and tested to guarantee set point repeatability.
• Twostage stem together with selfaligning disc and stem pivot point through ball joint ensures correct alignment of the seats and minimize the seat leakage for the spring force is applied equally at seat surface.
• Balance bellows ensures correct valve performance under various back pressure conditions.
• The material selection of guiding components ensures no galling of guiding surfaces.
• Trim for SSRW (for Liquid service)
  • Specific liquid trim designs give stable operation and full lift at 10% overpressure and discharge high capacity.
• Trim for SSR (for Air, Gas, Steam service)
  • Specific gas and steam trim designs give stable operation and eliminate the damaging effect of chattering
• Choice of disc and nozzle materials coupled with superior lapping techniques and precision machining provides high degree of seat tightness and good valve performance and continuous long term protection.
• The method of location of attachment to the body avoids transmission of pipe stresses to the nozzle/disc mating surfaces.
