What is a Y type strainer and filter?-its working principle and application

Today, we are going to talk about a common valve in the pipeline systems. This valve has a very important role. It is the Y type strainer or someone name it Y type filter. Y type strainer is an indispensable device for the pipeline system that conveys the medium. The Y type strainer is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to remove impurities in the medium to protect the valve and the normal working of the device. Let’s briefly introduce what a Y type filter is: 

What a Y type strainer and filter is? 

Y type strainer, also known as Y type filter, is an indispensable device on the pipeline of conveying mediums, usually installed in the front end of safety valve, pressure reducing valve, pressure relief valve, steam trap valve, fixed water level valve, globe valve and other industrial valves. Y type strainer is composed of valve body, a stainless steel screen, a sewage part, a transmission device and an electric control part( for some models of Y strainers, there are no control part). after the medium to be filtered passes through the filter screen, its impurities inside the medium are blocked. When the y type filter needs to be cleaned after a period of use, just take out the detachable filter screen and clean he filter device and the strainer screen. The screen can be re-installed, so the use and maintenance of Y type strainer is extremely convenient. 

Working principle of Y type strainer/Filter

The Y type strainer is a small device that can remove solids in the liquids. It can protect the normal operation of compressors, pumps and other equipment and instruments, to stabilize the process and ensure the safety. In addition, Y type filter is also important to improve the product quality. 

The Y type strainer is made of high quality stainless steel material. The inner cylinder is the stainless steel filter screen, is tightly fitted with a wire mesh structure, and they are connected by a joint. It is easy to disassemble and clean. Y type strainer is suitable for filtration of beer and CIP cleaning liquid, and can be matched with 20-100 mesh stainless steel wire mesh according to the actual use of the customers. Pipeline filter is a device for removing solid impurities in the process of pipeline transportation of liquid. When the liquid flows through the filter, the impurities inside are filtered out, which can protect the normal operation of the pump, compressor, instrument and other equipment. When the filter needs to be cleaned, just take out the detachable filter screen, remove the filtered impurities, and then re-install it, that Y type filter is extremely convenient for use and maintenance. 

Applications of Y type strainer/Filter 

Y type strainer has the advantages of compact structure, strong filtering capacity, small pressure loss, wide application ranges, convenient for maintenance. Its main applicable mediums are: weak corrosive mediums in chemical and petrochemical production,such as water, oil, ammonia, hydrocarbons,etc. Corrosive medium in chemical production, such as caustic, soda, soda ash, concentrated dilute sulfuric acid, carbonic acid, aldehyde acid,etc. Low temperature mediums in refrigeration, such as: liquid methane, liquid ammonia, liquid oxygen and various refrigerants. Material with hygiene requirements in food and pharmaceutical production,such as beer, beverages, dairy products,syrups,etc.
