PFA-Lined T-Strainer Purion9

Three choices. Basket type: PTFE or PTFE-carbon composite. Mesh: ETFE filter mesh from 85 to 2000 µm — choose the mesh from the size of the particles you need to retain: a finer mesh retains smaller particles and fills sooner, a coarser mesh passes finer particles and runs longer between cleanings. The mesh is usable to +150 °C; for higher temperatures a custom mesh (to +200 °C) is available. Bottom cover: standard or flush. A flush bottom cover has a drain bore with a DN 15 or DN 25 connection, so a ball valve can be fitted to drain the strainer and flush out the collected content — the basket is cleaned without removing the top cover. The bottom cover, including the bore, is fully PFA-lined. The drain valve itself is not included; we supply it on request.

PFA (virgin PFA) is the standard lining. PFA/AS is the antistatic version for media where electrostatic charge must be led off. PVDF is also listed for the body lining; ask us if your medium calls for it.

PFA lining anchored in dovetail grooves in the body — suitable for vacuum service; limits per P-T diagram or on request.

Pull the basket from the top; the strainer stays in the line. Impurities are removed with the basket, and a clean or spare basket is fitted. Baskets are also available as spare parts.

Every strainer is pressure-tested to DIN EN 12266-1 and ships with EN 10204 3.1 material certificates. It is designed and manufactured to PED 2014/68/EU.

Both are fully fluorinated plastics with almost universal chemical resistance. PTFE cannot be melted, so PTFE liners are pressed and sintered. PFA can be melted, so we transfer-mould it into the valve body: the lining is dense, anchored in the body and follows complex shapes. If your specification says "PTFE-lined", a PFA-lined valve meets the same chemical duty — ask us for a comparison for your medium.
