  • Handwheel operated
  • Clockwise close & anti-clockwise close

Main features

  • Quality certified by SAINT-GOBAIN PAM Engineering Department
  • Conception test according to Standard EN 1074-2 type B: - MOT: 1 x DN + 60 Nm - MsT: 5 x MOT + 300 with bending moment of 1500 Nm - Endurance test: 250 cycles
  • Hydraulic pressure test: - Body: 1,5 PFA = 24 bar - Seat: 1,1 PFA = 17,6 bar
  • Ductile iron construction provides high strength to weight ratio
  • Excellent corrosion resistance due to: - Epoxy coating thickness min. 250 µ - Wax-filled bolt holes
  • Stem O’ring seal arrangement suitable for replacement under pressure
  • Full clear bore for optimum flow
  • High tensile stainless steel stem ensures strength and corrosion resistance
  • Stem manufactured by cold forging process increases lifetime of the valve by excluding potential cracks
