Description
pfa lined electric butterfly valve
The pfa lined electric butterfly valve operates as an ideal solution for applications involving highly corrosive and toxic substances. The product includes a cast iron or ductile iron or aluminum or stainless steel or CF8 or CF8M or CF3M body structure with stainless steel and PTFE or stainless steel and PFA or F4 disc materials. The product features stainless steel stem components and PTFE and PFA or F4 materials for its seats while operating in sizes between 2″ to 24″ (50mm to 600mm). The valve supports EN 1092 PN 6/PN10/PN16 and ASME Class 150 and AS 4087 PN 10/ PN 16 and JIS 5K/10K flange standards are supported by this product.
The valve operates between -40 °C and + 180 °C (depending on pressure, medium and material) while using an ISO5211 top flange connection. The product exists in three body styles which include wafer and LUG and Flange configurations. The product features an electric actuator with output torque ranging from 50Nm to 2000 Nm and accepts control signals through 4-20 mADC and 0-5 VDC and 0-10 VDC and operates with power inputs of 12VDC, 24VAC, 24VDC, 220VAC, 120VAC and 380VAC at 50/60 Hz with ± 10% tolerance. The product includes two optional actuator options: Exd II CT5 Explosion proof and IP67 Water-proof.

FAQs
What is PTFE lined butterfly valve?
The PTFE lined butterfly valve exists to serve applications that need materials which withstand corrosion and abrasion and function under extreme temperature conditions. The disk-shaped butterfly valve operates in a position where materials flow through it. The disk-like valve component turns to generate an opening which enables material flow. The PTFE (polytetrafluoroethylene) liner inside this butterfly valve provides exceptional durability.
What material is used for butterfly valve lined?
Butterfly valves operate in multiple industrial settings which include water and wastewater treatment facilities together with chemical processing operations.
The selection of materials for specific applications depends on PTFE plastic and Viton/Fluoroelastomers and polyethylene and urethane and neoprene.
What is the difference between lined and unlined valves?
The main distinction between lined and unlined valves emerges from their construction materials. The body of unlined valves consists of hardened cast iron or steel materials. The body cavity and sealing surfaces of lined valves receive a special lining material which serves as their primary construction element. The main purpose of lining valves is to protect against corrosion and to shield steel or cast iron components from abrasive substances like slurries and particulates.
