Yoshitake SY-40EN is a ductile cast iron flanged Y-type strainer designed for steam, air, cold and hot water, and other non-dangerous fluids. It offers a maximum operating pressure of 1.0 MPa and a maximum temperature of 220°C. The SY-40EN features a stainless steel screen and complies with EN standard face-to-face dimensions for seamless pipeline integration.

Features

• Standardized Dimensions: The SY-40EN strainer can be replaced easily from existing strainers because it complies with face-to-face dimensions of the EN standard.
• High Flow Capacity: High-flow-rate marine type provided with the largest possible filtration area as a countermeasure against the decreasing in the flow rate caused by clogging.
• Compact Design: Sizes 65A or more are designed as compact as possible and reduced in weight, making plumbing easy.
