Custom RPTFE seal concentric flange butterfly valve gear box operation Factories, Factory
Product Description
| Valve Type: | Flange butterfly valve | Structure: | Concentric |
| Standard: | EN593 | Workmanship: | Investment casting |
| Sealing direction: | Bidirectional | Sealing grade: | Zero leakage |
| Temperature: | -20°C<T<120°C | Operation: | Handle/Lever |
The midline design significantly reduces the opening and closing torque, making manual operation more effortless. Pneumatic/electric drive has lower energy consumption and faster response (pneumatic opening and closing ≤ 2 seconds); The valve plate and valve stem are connected without pins, and flange disassembly and assembly do not require special tools. The lining layer can be repaired or replaced separately after wear, without the need to replace the valve body as a whole.
The flange connection is easy to disassemble and assemble, and vulnerable parts such as valve plates and seats can be replaced separately without the need to disassemble the valve body as a whole; After the lining layer wears out, it can be re sprayed and repaired to reduce equipment maintenance costs and downtime.
Supports DCS/PLC system integration control, can be paired with pneumatic and electric actuators; Optional explosion-proof certification execution mechanism can be selected to meet the safety requirements for use in flammable and explosive scenarios such as chemical, oil and gas industries.
Food grade PTFE lining meets FDA standards, with smooth inner walls that do not hang materials and are not prone to bacterial growth. It can be used in fluid delivery systems with high hygiene requirements such as pharmaceuticals, food and beverages.
Standard export wooden case packaging
Widely used in wastewater treatment, exhaust gas recovery systems, electrolyte circulation, acid pickling tank medium cut-off, high-temperature steam or corrosive gas regulation, but requiring temperature resistant lining.
