Flange type thin check valve

DN50-200
Product OverviewDouble disc butterfly check valve (double disc check valve), consisting of two semi-circular valve discs and built-in springs, with the medium pushing the double discs forward; When the pressure drops and flows back, the spring drives the valve disc to quickly close. Clamp between two flanges, with a very short length, it is an economical one-way valve that saves space.Technical parameters• Nominal diameter: DN40 to DN800• Nominal pressure: PN10, PN16, PN25Valve body material: ductile iron, 304, 316 stainless steelSealing materials: EPDM, NBR, PTFE, metal hard seal• Operating temperature: Soft seal -10~130 ℃; Hard seal up to 400 ℃• Connection method: clamp type (clamped between two flanges)Applicable media: water, air, sewage, seawater, general oil productsExecution standards: JB/T8937, GB/T13927Product advantages1. The structure is extremely short and lightweight, with only 1/4~1/8 of the length of the flange check valve, saving pipeline space and low cost2. Spring assisted closing, fast closing speed, effectively reduces water hammer impact, low noise3. Both horizontal and vertical pipelines can be installed, with flexible installation directions4. Moderate flow resistance, sensitive opening and closing, fast response speed5. No need for flange gasket matching, directly clamped, easy to disassemble and replace6. Economical pricing, outstanding cost-effectiveness of bulk water supply and fire protection pipelines
