Overview
The Keckley Style SB 1500 Y strainer is a proven, industrial-grade filtration valve for high-pressure pipeline applications. Built with ASTM A 216 Grade WCB carbon steel construction, this strainer handles 1500 PSI rated pressure and is suitable for steam, water, oil, and gas service. The Y-shaped body design allows inline installation with minimal flow disruption, while the removable screen basket can be cleaned or replaced without system shutdown when fitted with optional drain connections and service valves.
Key Features
- Robust Carbon Steel Body: ASTM A 216 Grade WCB casting ensures durability and corrosion resistance in demanding industrial environments.
- High Pressure Rating: Class 1500 rating for challenging high-pressure applications in steam, water, oil, and gas systems.
- Dual Connection Options: Available in NPT threaded and socket weld configurations to match existing piping infrastructure.
- Size Range: Nominal pipe sizes from ½” to 3″, covering most industrial flow requirements.
- Field-Serviceable Design: Drain connections and removable screen permit cleaning and maintenance while system remains in operation (when equipped with optional accessories).
- Precision Machining: All strainers meet ASME standards and are machined to exacting specifications for reliable performance.
