Eaton Model 85 Y-Strainer: Heavy-Duty Industrial Filtration

Overview of the Eaton Model 85 Y-Strainer

The Eaton Model 85 Y-Strainer is a robust, heavy-duty filtration solution designed to mechanically remove solids from flowing liquids, gases, or steam lines. Engineered for durability and compact installation, the Model 85 acts as a critical safeguard for process equipment, protecting pumps, meters, control valves, steam traps, and regulators from damage caused by debris.

As a distributor and OEM for top-tier filtration brands, Purecowater recommends the Model 85 for applications where heavy dirt loading is not expected, but protection against solid contaminants is essential. Its versatile design allows for installation in both horizontal and vertical pipelines, making it an adaptable choice for complex piping systems.

Key Features and Capabilities

The Model 85 is distinct because of its ability to handle aggressive industrial environments while maintaining a compact footprint. Unlike standard basket strainers, the Y-strainer design is streamlined, fitting easily into tight spaces without sacrificing pressure rating or performance.

• Heavy-Duty Construction: Available in Carbon Steel and Stainless Steel casting.
• Versatile Media Handling: Suitable for liquid, gas, and steam filtration.
• Flexible Installation: Can be installed horizontally or vertically (with blow-off facing downwards).
• Pressure Handling: Capable of withstanding pressures ranging from 275 psi up to 1,480 psi depending on the configuration.
• Standard Screens: Comes equipped with high-quality stainless steel screens.

Self-Cleaning Option

For applications where maintenance speed is a priority, the Model 85 can be fitted with a “blow-off” connection on the strainer cap. This feature allows for the cleaning of the screen without removing it from the strainer body, significantly reducing downtime during maintenance cycles.

Technical Specifications

The Eaton Model 85 is available in a variety of sizes and end connection types to suit different piping standards. Below is a breakdown of the standard configurations available.

Size Range	Material	End Connection	Rating (Non-Shock)
1/4″ to 2″	Carbon Steel	Threaded / Socket Weld 600#	1480 psi (102 bar)
1/4″ to 2″	Stainless Steel	Threaded / Socket Weld 600#	1440 psi (99 bar)
1/2″ to 10″	Carbon Steel	Flanged 150#	285 psi (20 bar)
1/2″ to 10″	Stainless Steel	Flanged 150#	275 psi (19 bar)
1/2″ to 10″	Carbon / Stainless	Flanged 300#	~720-740 psi

Flow Coefficient (Cv Factors)

Understanding the flow rate capabilities is vital for sizing the correct strainer. The Cv factor represents the flow capability of the strainer. The table below outlines the standard Cv values for water with a clean, perforated screen.

Size	Cv Value	Size	Cv Value
1/2″	4.2	2-1/2″	105
3/4″	9.5	3″	140
1″	16.2	4″	260
1-1/2″	37.0	6″	575
2″	67.0	10″	1500

Screen and Basket Options

The efficiency of the Model 85 relies on the proper selection of the straining element. Eaton provides high-quality stainless steel screens designed to fit perfectly into the strainer body, preventing any fluid bypass.

• Standard Material: Stainless Steel.
• Perforation Options: From 1/32″ up to 1/2″.
• Mesh Options: Available from 20 to 400 mesh for finer filtration needs.
• Monel Screens: Available upon request for specialized chemical resistance.

Why Choose the Model 85 for Your System?

Use of the Eaton Model 85 contributes to the longevity of your entire piping infrastructure. By mechanically removing unwanted solids, it ensures that expensive downstream equipment such as turbines and compressors remain operational without clogging-related failures.

Whether you are managing a steam line in a power generation facility or a liquid process line in a manufacturing plant, the Model 85 offers a cost-effective maintenance solution. Its synthetic fiber gaskets and bolted (for flanges) or threaded (for smaller sizes) covers ensure a secure seal even under high pressure.

Purecowater is ready to assist you in selecting the correct size, material, and screen configuration for your specific application requirements.
