Basic Information

RTO high-temperature flange hard seal ventilation butterfly valve double flange connection

1、 Product Overview and Usage:The RTO triple eccentric zero leakage butterfly valve is designed as a flange type; Especially adopting a rear seat ventilation structure, there is no jamming phenomenon under low or high temperature conditions; It has the advantages of flexible opening and closing, and automatic sealing compensation with trace elasticity. The Faden RTO triple eccentric zero leakage butterfly valve is suitable for regulating gas flow in environmentally friendly RTO, chemical, power plant, metallurgical, cement and other industries.2、 Main performance specifications:1. nominal diameter: DN (mm) 50-30002. Nominal pressure: PN (Mpa) 0.05-0.33. Strength test pressure: PS (Mpa) PN x 1.5 times4. Applicable temperature: t (o C) ≤ 6505. Leakage rate: 0 leakage6. Applicable media: exhaust gas, air; Dust gas; Harmful gases such as cold and hot7. Medium flow direction: in any direction8. Control form of medium: fully open Fully closed and adjustable within the range of 0-90 degrees3、 Characteristics and standards:1. This valve is welded with steel plates, which is small and lightweight, easy to decorate. The double design of the fitting part enhances its firmness.2. Due to the vertical structure of the butterfly plate, the overcurrent area is large, the flow resistance is small, the switch is flexible, the operation is convenient, and it saves time and effort3. Welding data: According to GB/T12224-2005 and GB/T19866-2005.4. Drive device standards: comply with JB/T8864-2004, JG/T8528-1997, GB/T12222-1989Waiting standards.5. Manufacturing and acceptance shall comply with QB/THQB0102-1999, GB/T26480-2011, and JB/T248-1985.If the temperature is too high, add a heat sink component to the neck to cool down and protect the driving device.4、 Main component materials:Valve body and butterfly plate: Carbon steel 16Mn 1Cr18Ni11Ti 316L 2Cr25Ni20阀杆: 2Cr13 45# 4Cr14Ni14W2Mo 321 316 2Cr25Ni20Sealing surface: Stainless special steelPacking: Expanded graphite asbestos packing
