PTFE lined butterfly valve is widely used for chemically toxic and highly corrosive media, the special design of the sealing ensures the reliability and safety in high-risk workplaces. 1. Design in split Type body, the parts of the valve can be disassembled, material-specific recycling possible 2. Maintenance-free, the valve can be installed in any desired position 3. ISO 5211 mounting pad for easy and quick actuator installation 4. Positioning holes keep valve in the center between pipe flanges and also applied to many international standards. 5. Three different sealings ensure the lined butterfly valve in high performance. 6. Three self-lubricating sleeves could keep stem not be deformed under pressing. 7. When the four Belleville Spring under pressing, it will make sealing among the gland, the seat and the disc edge more tightness 8. Epoxy coating with baked finishing before valve assembly, keep inner body can’t be rust. Media temperature: -20℃ to 200℃ (depending on operation the pressure and the fluoroplastic material )lg...

The MVI PTFE ball check valves are developed for using on fluids compatible with the corrosion resistant characteristics of virgin PFA seat. These valves can be used in horizontal and vertical installations. The body parts of the valve do not contact with the process flow. The lined ball type check valve is widely used for chemically toxic and highly corrosive media. Technical Specification • Design Standards: API594• Flange Ends: ASME B16.5, Class 150, DIN 2532 PN10/16, JIS B2212,Raised Face• Face to face: ASME B16.10, DIN 3202, JIS B2002• Inspection and Testing: API 598, DIN 12569, JIS B2003lg...

MVI weir type diaphragm valve having rugged design to incorporating the best material available is proved by easy, smooth and maintenance free operation for a long time. Extra heavy-duty casting affords high resistance to atmospheric corrosion. MVI diaphragm valve reduces diaphragm travel for extended service and fine control. A wide choice is available for body materials, the linings, types of operation and the end connections to satisfy of the most industrial applications. High quality standards are strictly maintained each valve being checked for size, design pressure, operation MOC, finish etc.  Normally the ASTM A216 WCB body with full lining PFA fluoroplastics. Minimum thickness of PFA lining around of 3mm. For some chemicals not so aggressive, the FEP grade fluoroplastic material also is available for economic choice. Due to the diaphragm depart up and down the bodies, this design will let the body and stem not contact aggressive medium to avoid corrosive problem. Technical Specifications: 1. Size range: 1/2"-12"(DN15-300) 2. Working pressure range: 10Bar (Max) 3. Body Material: ASTM A216 WCB, A351 CF8/CF8M 4. Seat: PFA (or FEP material also is available) 5. Membrane Material: EPDM with PFA or PTFE or FEP 6. Temperature range: -20℃-200℃(depending on the fluoroplastic material ) 7. Flange Ends: DIN2532, ASME B16.5 (or customized) 8. All the lined valves should be done 14kv spark testlg...
