Yoshitake SY-40R series (SY-40R-A and SY-40R-B) strainers are designed for water and oil applications. Constructed with a ductile cast iron body and a stainless steel screen, these strainers support a maximum working pressure of 1.0MPa and a maximum temperature of 90°C. The series offers specific models for different piping orientations to ensure optimal performance and maintenance access.

Recommendation

The SY-40R series is highly recommended for labor-saving or man-hour-saving facilities that require frequent screen cleaning.

Features

• SY-40R-A: Designed specifically for horizontal piping.
• SY-40R-B: Designed specifically for vertical (upper→bottom) piping.
