Application

• Body and disc materials: 304, 304L, 316, 316L(body/disc material and forming process are determined according to the actual service conditions).
• Seat sealing materials: PTFE, PFA, etc.
• Suitable for data centers and similar applications.
• Please consult the company for any special technical requirements.

Standards and Specifications

Design Features

• Bidirectional gas-tight sealing with zero leakage: the valve seals at equalpressure in both directions, regardless of flow direction.
• Stem bushings provide maximum support for the valve stem, togetherwith corrosion resistance and resistance to deformation under mechanical loads.
• The stem packing can be adjusted without disassembly; internal travel stops prevent over-closing, reducing seat wear and extending service life.
• The body cavity and disc are mirror-polished to meet liquid-cooling service requirements.
• ROBVALVE high-performance butterfly valves deliver excellent operatingperformance and a service life of up to 100,000 open/close cycles.
• Optimized lip-type seat design automatically compensates for temperature and pressure variations, delivering safe and reliable sealing performance.
• Emergency on-site maintenance: simply remove the retainer plate and replace the standard seat - no need to disassemble the disc or stem.
• The standard V-type PTFE stem sealing system lowers operating torque, reduces wear at all contact points, and complies with international fugitive-emission standards.
• Two-piece stem design increases the valve's flow capacity.
