Flange / Weld Connection Cryogenic Butterfly Valve for PN1.6 - 16.0 MPa Pressure

ZSHWED Series Cryogenic Butterfly Valve, adopt special triple offset design, with characteristics of impact structure, good shut-off performance and long service life. And it has both regulating and shut-off functions. The size is DN801600mm(NPS364),Pressure is PN1.6~16.0MPa(Class150~900).                                  

Feature:

• One-piece casted body with the feature of compact structure and lightweight
• The triple offset valve advanced design features three-way eccentricity and unique elliptical seat geometry ensuring compressive sealing around the entire seat and a tight, bubble free valve.
• Sealing ring design is novel, concise, free repair
  • Stainless steel and graphite laminated seal ring provides reliable, zero leakage, bi-directional shutoff
• Triple offset structure ensure non-rubbing rotation, minimizing torque required and maximizing seat/seal ring lifetime
