Y-Strainers also commonly known as Wye-Strainers are intended to remove and retain debris and small solids from hydronic, steam or gas systems by means of a small stainless mesh screen. The strainer comes with an angle outlet with a tapping at the bottom (forming a letter "Y" and hence the name), which accumulates the debris and can be cleaned (purged) by removing a factory installed plug.
The main purpose of a Y-Strainer is to protect valuable system components, such as boilers, heaters, heat exchangers and pumps from build-up of sediments and early failure and to reduce frequency and costs of equipment maintenance.
Features heavy-duty pattern, 18 mesh size stainless steel screen and factory plug. Threaded connections comply with ANSI B2.1.
Lead-Free Compliance: Only lead-free wye-strainers are approved for use in potable water systems (where water is intended for human consumption). Regular bronze models can be used for all other applications - heating, cooling, etc.
Frequently Asked Questions:
Q: How do I know which side is inlet or outlet?
A: The strainer has an arrow on it's body pointing the direction of the flow. Also, the sediment collector branches off in the same direction as the flow.
Q: What's the best way to install a Y-strainer - vertically or horizontally?
A: It can be installed in either position as long as the tapping at the bottom of the sediment collector is pointing down. This way, the solids can be properly entrapped and easily purged.
Q: Which is better - Bronze or Cast Iron?
A: Bronze is, without doubt, a more reliable material in all aspects. Due to the nature of the wye-strainer, it is supposed to filter the sediments, not produce them. Cast iron strainers are highly subject to corrosion and with time, will likely produce flakes of iron oxide which will be carried by the flow to the very equipment that requires protection against them.
