Quick Selection Guidance (seat/seal vs. service)

Strong acids / oxidizers: PTFE/Teflon lining + PTFE/RPTFE seats, FFKM stem seals if >150°C

Strong alkalis: PTFE/Teflon + PTFE seats; FKM or EPDM packing per CIP chemistry

Solvents/aromatics: PTFE/Teflon + RPTFE seats; FFKM seals to minimize swelling/permeation

Slurries/abrasives: PTFE/Teflon + reinforced RPTFE seats, full-bore to reduce erosion

 

 

Features:

Full PTFE/Teflon Lining – Complete lining of body and ball for superior resistance to acids, alkalis, and solvents.

Zero Leakage – High-performance seats and PTFE/Teflon lining ensure tight shut-off and safe operation.

Wide Temperature Range – Standard −20°C to 200°C, optional up to 220°C or low-temperature service.

Material Flexibility – Carbon steel or stainless steel body with PTFE/RPTFE/PFA seats to match different media.

Automation Ready – ISO 5211 mounting for manual, pneumatic, or electric actuators.

Low Maintenance – Smooth PTFE/Teflon surface reduces deposits and cleaning frequency, extending service life.

International Standards Compliance – Designed and tested per MSS SP110, ASME, EN, JIS, API standards.

 


 

Pain Points & Solutions:

Corrosive Media Damage → Full PTFE/Teflon lining isolates corrosive fluids, extending valve life.

Clogging from Viscous or Solid Media → Full-bore flow ensures smooth passage and reduces downtime.

Frequent Leakage Issues → High-performance seats plus lining provide zero leakage for safety and compliance.

Temperature/Pressure Fluctuations → Designed for high/low temperature and adjustable seat/seal options.

Difficult Automation Upgrade → ISO 5211 standard interface allows easy actuator installation.
