Model 72-44F


Model 72 and 72F series bronze or aluminum strainers are furnished in both standard and high pressure models with flanged of NPT threaded port connections. Internal channels are 100% full-flow, having the same cross-sectional area as the equivalent pipe size. Standard pressure models are furnished with our quick-opening, hand-clamp for easy access. High pressure models are stud-and-nut body cover closures. Refer to our drawings A2346 and A2347 for sizes, ratings and dimensions. Materials of construction Include rugged cast bronze or aluminum bodies, covers and valve plugs, and brass, stainless steel or monel baskets. Special valve plugs can also be furnished in stainless steel or other materials.

These duplex strainers have a built-in, tapered plug valve that directs flow through either side without shutting off the flow. A valve handle guard shields the side in use. The standard valve handle swings over the inlet port. Special reverse valve handles that swing over the outlet port can also be furnished. Drain plugs are provided in each of the valve and basket chambers. An adjustable locking flange holds the valve plug on its seat. A separate, external gland is provided to allow easy access to valve stem packing without complete disassembly, even while in service.

Strainer baskets are fabricated from perforated metal. The smallest common perforation size is 1/64 inch in brass and 1/32 inch in stainless steel. Filter baskets are manufactured by using fine mesh wire cloth over supporting perforated metal. Interchangeable strainer, filter and double element baskets provide a flexible range of operating choices. The basket is held on its seat by a spring basket handle. Normal flow is through the interior of the basket which then contains the collected debris when the basket is lifted out for cleaning. Reverse flow is also possible if desired. Magnet inserts are available to help eliminate fine metallic ferrous particles.

All high pressure models with stud-and-nut closure are supplied with balancing valve assemblies to equalize pressure and ease valve turning. These should be specified on standard pressure models when used above the following pressures: 3/4" through 1-1/2" inclusive, 100 psig; 2" & 2-1/2', 80 psig; 4 inch through 8 inch - 15 psig.
