PTFE Lined Basket Strainer Filter
PTFE Lined Basket Strainer Filter Manufacturer
The PTFE Lined Basket Strainer Filter is an ideal solution for highly corrosive and aggressive fluid handling systems that demand both effective filtration and superior chemical resistance. Manufactured by MVS Valves with a fully lined internal surface, this strainer combines the mechanical strength of a metal housing with the inertness of PTFE, FEP, or PFA linings, making sure long service life and reliable operation even in the harshest chemical environments. Mayur (Valves) System Private Limited, an ISO 9001:2015-certified company, has been a trusted PTFE Lined Basket Strainer Filter manufacturer and exporter since 1978. We export to 40+ countries worldwide, focusing on consistent quality, timely delivery, and a smooth customer experience. Our products serve clients across Europe, North America, the Middle East, Southeast Asia, Russia, and other international markets, providing dependable filtration solutions for diverse industrial applications and process requirements.
Designed to filter out solid impurities from process streams, this strainer uses a perforated basket-style insert lined with fluoropolymers, which minimizes pressure drop while maintaining flow efficiency. The design also facilitates easy removal and cleaning, ensuring uninterrupted operation and minimal maintenance. The lined flush bottom tank valve integration option allows for efficient drainage and cleaning, especially in vertical installations.
In demanding industries where performance cannot be compromised—such as pharmaceuticals, chemical processing, petrochemicals, and wastewater treatment—this anti-corrosive lined flush bottom valve system proves indispensable. We offer variants including the PFA Lined Flush Bottom Valve, FEP Lined Flush Bottom Valve, and specialized Lined Y Type Flush Bottom Valve models, suitable for use in tanks and pipelines requiring bottom discharge solutions.
For actuator-based automation, Pneumatic Lined Y Type Flush Bottom Valves provide efficient control, while stainless steel options such as SS 304 Y Type Lined Flush Bottom Tank Valve and SS 316 Y Type Lined Flush Bottom Tank Valve are also available for enhanced strength and corrosion resistance. Whether you need a PTFE Lined Flush Bottom Valve Manufacturer or a FEP Lined Flush Bottom Valve Exporter, MVS Valves delivers globally trusted solutions designed for durability, safety, and process efficiency in corrosive media applications.

What is a PTFE lined basket strainer and how does it work?
A vertical basket-type strainer with the shell and end cover fully lined and a PTFE or FEP filter element. Flow enters the shell, passes outward through the basket, and the debris stays inside it. The basket presents a far larger screen area than a Y strainer of the same line size, so it holds much more before the pressure drop rises — and it lifts straight out through the cover for cleaning without breaking the pipework.
Which shell, lining and filter materials are available?
Body shell in ASTM A106 Gr. B (SCH-40), FEP lined. End cover in IS:2062, FEP lined. Filter element in PTFE or FEP. Studs and nuts in stainless steel. Lining options PFA (ASTM D3307) or FEP (ASTM D2116), at 3–5 mm.
What size, test pressures and standards apply?
DN 25 (1″) to DN 150 (6″). Flange standard ANSI B16.5, with drilling to ASA #150, DIN 2632/33 or BS 10 Table D, E, F. Body pressure test 20 kg/cm², plus a 15 KVDC spark test. A T type strainer design is available as an optional variant.
When is a basket strainer worth the extra cost over a Y strainer?
Whenever the line carries continuous or heavy debris, or the flow is large enough that a lined Y strainer would blind quickly. The larger screen area means longer intervals between cleans and a lower steady pressure drop, and the basket comes out through the cover rather than requiring the strainer to be opened at the flange. On a line that has to run continuously, that difference is usually decisive.
Are you a manufacturer, and what are your minimum order quantity and customization options?
MVS is a manufacturer — building at its own works since 1978, ISO 9001:2015 certified — and exports across several continents. The minimum order quantity is 20 pieces. T type designs, PFA lining, alternative filter grades and non-standard flange drilling are built to order.
