Nanjing Fuyuan Chemical Pipeline Equipment Co., Ltd.  

Product Name: Professional China Supplier of PFA Lined Ball Valve Model NO.: FK/FKP Series Application: Industrial Usage, Water Industrial Usage Type: Floating Ball Valve Structure: Floating Ball Valve Channel: Straight Through Type Connection Form: Flange Material: Stainless Steel Size: Dn15~Dn100 Trademark: Fuyuan Transport Package: Wooden Case Specification: SGS, ISO Origin: China Product Description Chemical plants PFA lined ball valveApplicationBall Valves lined with PFA or FEP provide trouble free service in acid environments, they are commonly used in pulp and paper operations,Chlorine water, Chlorine dioxide, Sodium hypochlorite and sulphuric services.Advantages:l Integrated ball/valve stem with anti- expulsion design.l The lining of valve and ball can provide the general chemical corrosion-resistance materials as PFA & FEP by requirements.l As for the innovative plate-type PTFE bellows filling structure, it can automatically adjust between the movable filling gland ring and spring tableting, and even though under the condition of heat-cool cycle, the filling always has high leak tightness and reliability for pre-selection loading.l Even though on condition of frequent alternation between coldness and heat. it can realize the sealing effect for the flange of metal to metal mode.l It has unified lining thickness in the sealing area to promote the ability for resisting the permeable medial Strengthen the surface loading ability for labyrinth sealing through casting sealing lip. Carry long life PTFE valve seat.l It adopts special spring valve seat design to ensure permanent leak tightness within the range of the entire pressure/temperature, including in condition of vacuum.l It can choose the lining with antistatic property.l PFA and FEP thermo-plastic valve lining with 3.5 mm's thickness, anti-seep, anti-corrosion and anti-vacuum.l As for the high penetrability medium, it can adopt 5mm's lining for the over-current part in the valve.SpecificationsDesign: ISO, flanges drilled to ASME B16.5 Class 150, full boreFace to face: ASME B16.10Housing material: Ductile cast IronProduct: PFA lined bellows sealed ball valveDesign: ISO, flanges drilled to ASME B16.5 Class 150, full boreFace to face length: ASME B16.10Housing material: Ductile cast IronLining: PFAActuation: Manually operatedStem: SS304 Blow-out proofBall: SS304 PFA linedPainting: Epoxy paintOne Piece ball and stem PFA Lined full port, Blow-out proofOption:Stainless steel Anti-Static Spring.Stainless steel lock1, 1 1/2, 2, 3, 4 inch available.DN15202540506580100L140140150180200220250280H130130130155155165180195HL165165165240240280315315
