For unparalleled durability and low lifecycle cost, cast iron Tate Andale Model AL and AH Twin Basket Industrial Strainers are the workhorses of the industry. Featuring bank vault construction and only one set of moving parts to minimize wear, the AL, AH, and R are designed to outlast and outwork all others.
Sliding gate valves are the only moving parts, and they feature wedge seating so there’s no contact with the body during the chamber changeover process, reducing wear and extending equipment life. And with the lowest pressure drop available, the AL, AH, and R offer the lowest operating cost.
