  • Replaceable Nozzle & Easy maintenance procedure
  • Soft seating arrangement for tight shut-off
  • Stellited trims for High Pressure and Temperature
  • High Efficiency And Better Performance
  • The material selection of guiding components with self aligning disc ensure no gailing of guiding surface.
  • High Efficiency Spring

APPLICABLE CODE/ STANDARDS:       

  • ASME BPVC Section VIII Division I
  • API 520/API526/API527
  • ASMEB 16.34
  • ASMEB 16.5
nozzle

( 1 ) Nozzle Design :- The Nozzle is Pressure parts & in continuously contact with the flow media in both the condition, it so design and : attached with the body to avoid transmission of pipe stresses to the contact surface.
( 2 ) Adjustable Blow Down : The blow down or reset pressure can be simply adjusted to meet the special or specific performance requirements by means of a single adjusting ring.
( 3 ) Trims : Specific trims design & precise machined components are ensures the performance of the valve under critical applications without trouble free long life.
( 4 ) Guiding Area : The material selection of guiding components, together with a self-aligning disc and spindle pivot point, ensures correct alignment and no gelling of guiding surface
( 5 ) High Performance Spring : Design accuracy and selection of spring ensure the repeat-ability of the set pressure. Bellows: Ensure correct valve performance under difficult back pressure conditions.
Seat Leakage integrity : Selection of nozzle and disc materials with precise lapping gives positive shutoff comply with relevant standard and prevents loss of flow media.
