LF352

Product catalog summary

Overview: The document provides technical specifications for the LF352 and LF358 models of Lead Free Brass Screwed and Solder Y Type Strainers, used primarily in potable water systems to filter out foreign matter and protect mechanical equipment.

Typical Service: These strainers are extensively used to protect pumps, meters, valves, and other mechanical equipment by straining foreign matter from pipelines.

Features:

Constructed with a Lead Free Brass Body and Cap.
Y Pattern design with a tapped retainer cap and closure plug included.
Special flared screen opening on the upstream end for unrestricted flow.

Construction: The strainers feature a straight threaded, gasketed cap for easy disassembly and assembly.

Self-Cleaning: Self-cleaning is facilitated by opening the plug or valve connected to the blowoff outlet.

Blowoff Outlets: These outlets are NPT tapped, and a closure plug is included.

Capacity: The strainers have generously proportioned bodies with an open area ratio much greater than the pipe size, ensuring a low pressure drop.

Working Pressure - Non Shock:

LF352: 400 psi @ 150°F for sizes 3/8" to 2"; 300 psi @ 150°F for sizes 2 1/2" to 3".
LF358: 385 psi @ 180°F for sizes 3/8" to 2"; 300 psi @ 180°F for sizes 2 1/2" to 3".

Screens: Standard water model sizes range from 3/8" to 3" with 304SS material and 20 mesh opening.

Pressure Drop: Flow curves indicate the flow (gpm) and pressure drop (psig) through the models using a standard 20 mesh screen.

Dimensions and Weights: Detailed dimensions and weights are provided for both LF352 and LF358 models, with variations based on size.

Material: Both models are made from Lead Free Brass for the body, cap, and plug, with NBR gaskets.

Compliance: The wetted surface of the product contains less than 0.25% lead by weight, complying with lead-free standards.
