SDS Series

Champion Valve’s SDS™ API‑6D short‑pattern check valve delivers robust single‑disc performance through a fully retained disc design that maintains controlled, full‑range motion under dynamic flow conditions. Its compact wafer profile provides a space‑efficient, economical solution, while the valve’s threaded lifting hook streamlines handling and precise alignment during installation. With integral metal, RPTFE, and resilient sealing options and a body‑sealing O‑ring on resilient‑seated models, the SDS ensures dependable shutoff across liquid, steam, and gas systems in demanding industrial environments. Ideal for liquid, steam, and gas systems, the SDS is widely used in refining, chemical processing, power generation, water and wastewater, and general industrial flow control.

• API‑6D Compliance: Meets API‑6D short‑pattern wafer specifications for proven reliability in critical pipeline service.
• Compact Wafer Profile: Short‑pattern body minimizes face‑to‑face dimensions for tight piping layouts and reduced system footprint.
• Fully Retained Disc: Disc is captured within the flange faces, ensuring controlled motion and preventing over‑travel under dynamic flow.
• One‑Piece Body Construction: Eliminates external leak paths and enhances pressure‑boundary integrity in demanding applications.
• Versatile Seat Options: Integral metal, RPTFE, and resilient seats support a wide temperature range and diverse media conditions.
• Body‑Sealing O‑Ring: Resilient‑seated models include an integrated O‑ring for leak‑proof body sealing.
• Robust Material Selection: Available in carbon steel or 316 stainless steel for compatibility with corrosive, high‑temperature, or general industrial service.
• Threaded Lifting Hook: Simplifies handling, alignment, and installation, especially in larger diameters up to 24".
• Low‑Maintenance Operation: Economical design with minimal wear components reduces lifecycle cost and service requirements.
• Multi‑Media Capability: Engineered for reliable performance in liquid, steam, and gas systems across industrial environments.
