The Sterlco® Low Pressure Radiator Trap (The Sterlco® Smart Trap) will operate efficiently regardless of steam pressure variation. All thermostats and seats are replaceable without shimming or adjustment. Every trap is thoroughly tested. Components are inspected and tested during manufacture; completed traps undergo complete operating tests before shipment.
Trap bodies, covers, union nuts and nipples are close grained red brass castings. Accurate machining assures steam-tight fit and complete interchangeability of parts. Sterlco® low pressure 750-A traps have valve cones of long-wearing tobin bronze and seats of brass. Stainless steel cones and seats are available 1/2” 750-A trap.
