381 Iron Wye Strainer
Protect pumps, valves, and meters from damaging particulates with the 381 Iron Wye Strainer, engineered for rugged performance in industrial water, oil, and gas systems. Featuring a durable cast iron body, corrosion-resistant SS304 perforated screen, and ANSI-compliant flanged ends, this Y-strainer combines robust construction with easy maintenance. Its unique angled design minimizes pressure drop while maximizing debris collection efficiency.
Key Features & Benefits
- Y-Strainer Efficiency: Angled design allows continuous flow during cleaning and reduces system downtime.
- Dual-Pressure Rating: 125# WSP (Working Steam Pressure) / 200# WOG (Water, Oil, Gas) for versatile applications.
- SS304 Filtration: Perforated screen resists corrosion, with optional 20-mesh wire screen for finer particle capture.
- ANSI B16.5 Flanges: Ensures leak-proof compatibility with standard industrial piping systems.
- Bolted Cap with Clean-Out Plug: Simplifies screen access and debris removal without full disassembly.
Technical Specifications
- Body Material: Cast iron.
- Screen Material: SS304 perforated plate (standard) + optional 20-mesh SS304 wire screen.
- End Connections: Flanged (ANSI B16.5).
- Pressure Rating: 125# WSP / 200# WOG.
- Design: Bolted cap, 45° Y-pattern.
Ideal For
- Industrial water supply lines with high sediment loads.
- Oil and gas pipelines requiring coarse filtration.
- Steam condensate systems in power plants.
- HVAC cooling towers prone to debris buildup.
Why Choose the 381 Wye Strainer?
This strainer stands out with its maintenance-friendly Y-configuration, allowing debris to collect in the low-velocity chamber without interrupting flow. The reinforced cast iron body withstands high-pressure surges, while the dual-screen option (perforated + wire mesh) provides customizable filtration for varying particle sizes. Designed for longevity in harsh environments, it’s the go-to solution for protecting critical equipment.
Built to filter – engineered to endure.
