Product Features
▶ Pneumatic Actuation, Fast Response
Uses a pneumatic piston drive for quick actuation—opening and closing in milliseconds.
▶ Angle‑Seat Design, Low Flow Resistance / High Flow Rate
The angled stem-to-seat arrangement allows straight‑through flow, yielding a low flow coefficient and high nominal diameter utilization.
▶ Stainless Steel Body, Corrosion‑ and High‑Temperature Resistant
Standard 304 or 316L stainless steel construction resists a wide range of chemicals; can handle steam service up to and beyond 180 °C.
▶ Self‑Cleaning Seat to Prevent Deposit Buildup
The lift‑type seat‑plug interface creates a self‑cleaning action on closing, effectively preventing blockage by particles or sediments.
▶ Flanged Connection, Easy Installation / Reliable Sealing
Standard ANSI/DIN flanges enable fast integration with piping systems; O‑ring or PTFE gaskets ensure excellent sealing.
▶ Broad Range of Compatible Media
Suitable for water, oils, air/gases, as well as saturated steam and mildly corrosive chemicals.
▶ Wide Temperature / Pressure Ratings
Available pressure classes PN16 and PN25; operating temperature from –10 °C to +180 °C (variant depending on seal material).
▶ Long Service Life, Simple Maintenance
Wear‑resistant stem and body materials plus high‑quality seals deliver hundreds of thousands of cycles; bonnet is quickly removable for on‑site replacement of wear parts.
▶ Sanitary Grade / CIP‑Capable
Smooth, dead‑zone‑free internal cavity meets the needs of food, pharmaceutical, and other processes requiring Clean‑In‑Place.
