Mueller Strainer

Stainless steel Y-Strainers are used where high corrosion resistance or where freedom from contamination is required. They are popular in the chemical, food and pharmaceutical industries.

Another critical thing to check for in Y-Strainers is the point where the screen or straining element seals to the body. This seat should be carefully machined so no particle can bypass it. The same thing applies to the cleanout end. The screen should fit tightly. Beware of strainers with un-machined seats. The improperly seated screen will permit bypass of the fluid allowing dirt or debris downstream.

Unlike other types of strainers, a Y-Strainer has the advantage of being able to be installed in either a horizontal or vertical position. Obviously, in both cases, the screening element must be on the "down side" of the strainer body so that the entrapped material can properly collect in it.

A Y-Strainer, if fitted with a blow-off connections, can be a self-cleaning strainer. A valve is installed on the connection located on the strainer cap. The screen can thus be cleaned by simply opening and then closing the valve without shutting off the flow or disassembling the strainer. When the valve is opened the material trapped inside the screen drains out. The illustration above show a Y-Strainer with a blow-off connection.

Y-Strainers are used in a wide variety of liquid straining applications to protect downstream process system components in many industries, including: chemical processing, petroleum, power generation and marine. Water handling applications, where Y-Strainers are used to protect equipment that could be damaged or clogged by unwanted sand, gravel or other debris, are very common

Some manufactures reduce the size of the Y -Strainer body to save material and cut cost. Before installing a Y-Strainer, be sure it is large enough to properly handle the flow. A low-priced strainer may be an indication of an undersized unit.

Special flanges such as ring joints are often available as well. Y-Strainers can be constructed to US Navy flange dimensions, which are different from commercial standards. For extremely high pressure applications, Y-Strainers with socket or butt weld end connections are often specified.

This 4 IN double check detector backflow preventer assembly prevents the backflow of pollutants that are objectionable but not toxic, from entering into the potable water supply. Its compact housing consists of two independently operating tri-link check valves, two shutoff valves, and four test cocks. It has a gallons per minute meter. It features a stainless steel housing and sleeve and is 70 percent lighter than traditional designs. It is designed for non-health hazard applications and may be installed under continuous pressure service to protect against both backpressure and backsiphonage. It is used primarily on fire sprinkler lines when it is necessary to monitor unauthorized use of water. The maximum working pressure is 175 psi (12.06 bar).

Y-Strainers are very cost effective straining solutions in many applications. Where the amount of material to be removed from the flow is relatively small, resulting in long intervals between screen cleanings, the strainer screen is manually cleaned by shutting down the line and removing the strainer cap. For applications with heavier dirt loading, Y-Strainers can be fitted with a "blow-off" connection that permits the screen to be cleaned without removing it from the strainer body.

Besides steam, Y-Strainers are often used in air and natural gas applications. Here again, high pressures are not uncommon. However, unlike steam high air pressure does not automatically mean high temperature and so, ordinary carbon steel bodies of sufficient wall thickness will generally suffice.
