Cryogenic Butterfly Valve with Stainless Steel and Graphite Laminated Seal Ring No Leakage
SS Cryogenic butterfly valve
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
