Cast iron basket strainer with knob cover and stainless steel screen

Mueller Steam Specialty

Mueller Steam Specialty 1/2" 125 CI Iron Body Screwed Basket Strainer

SKU CH-3VAD-1TQR0

Cast iron basket strainer with 304 stainless steel screen filters water at 14 gpm flow and 200 psi pressure rating

  • Handles 14 gpm flow with 200 psi rating
  • 304 stainless screen traps particles down to 0.062 in
  • Cast iron body resists corrosion to 150 °F
  • Buna-N gasket seals reliably from -20 °F to 100 °F
  • Knob cover allows quick basket access for cleaning

1/2" NPT Basket Strainer for Water Systems

This cast-iron basket strainer connects via 1/2" NPT threads and is designed to filter debris from water lines. Its 304 stainless-steel screen with a 0.06 in mesh captures particles while maintaining a Cv flow factor of 14 gpm. The unit suits commercial and industrial plumbing where reliable particle removal is required.

Sustained Flow and Pressure Performance

Rated for a maximum pressure of 200 psi at 100 deg F, the strainer handles continuous service without deformation. The Buna-N gasket and knob-type cover maintain a positive seal during extended operation. Stainless-steel screen construction resists corrosion, preserving the 0.062 in perforation size over long periods.

Temperature Range and Installation Profile

Operating limits span -20 deg F to 150 deg F, accommodating chilled and hot-water circuits. The compact 6-1/2 in height and 4-9/16 in length fit standard piping layouts without special supports. Cast-iron housing and NPT connections add mass that dampens vibration and reduces transmitted noise in normal use.

Questions about this item

Does the cast-iron body and Buna-N gasket handle continuous 150 °F water without leaking?

The strainer is rated for a maximum temperature of 150 °F and a maximum pressure of 200 psi at 100 °F, with a Buna-N gasket and cast-iron housing designed for water service.

What pipe thread and screen come in the box so it installs without extra parts?

It includes a 304 stainless steel screen with 0.062 in perforations and has 1/2 in NPT connections, so it threads directly onto matching pipe.

Will the 14 gpm Cv flow factor restrict flow in an older 1/2 in steel piping system?

The Cv of 14 gpm indicates the pressure drop across the strainer at that flow rate; compare it to your system's available pressure to confirm compatibility.
