DN1.6m pneumatic RTO ventilation valve hard seal high temperature flue gas butterfly valve
Normal temperature large diameter pneumatic ventilation butterfly valve flange gas medium valve simple structure, small size, light weight, only composed of a few parts. And only need to rotate 90 can be quickly opened and closed, easy to operate, while the valve has good fluid control characteristics. Butterfly valve is in the fully open position, butterfly plate thickness is the resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics, butterfly valve small volume, small space. Good sealing performance, the specific selection of time, or according to the medium, temperature, pressure, etc. to select, pneumatic carbon steel flange ventilation butterfly valve cold air special zero leakage ventilation valve installation is to use stud bolts to connect the valve between the two pipeline flanges. It is increasingly widely used in pipelines, and it is also increasingly valued by users and valve manufacturers. Pneumatic, electric and manual devices can be configured according to user requirements to meet the needs of remote control and program control.
First, the body is coated with epoxy resin, which is not easy to drop paint.
Body materials: cast iron, cast steel (WCB), stainless steel, aluminum alloy (ADC12), PVC
1, cast iron: CI gray iron (easy to break), DI ductile iron (good strength, can replace WCB)
2, WCB: cast steel, goods for a long time, less than 16KG can be replaced by DI
3, stainless steel: 304, 316, 304L, 316L
4, aluminum alloy: code ADC12, aluminum alloy butterfly valve is also called anti-condensation valve, generally used in lighter PVC pipe anti-condensation characteristics reflected in the application of air conditioning water system, indoor and outdoor temperature difference, water droplets easy to condense, choose aluminum alloy material can avoid this phenomenon, avoid penetration.
5, plastic: (general pressure is about 6KG, more than 10KG customers are recommended to use aluminum alloy replacement) UPVC,: weak acid and weak base resistance, high impact strength, low fluid resistance, light texture, good sealing PP: hydrochloric acid, sulfuric acid, corrosion resistance, CPVC: heat resistance, acid, alkali, salt, oxidant and other corrosion.
II. Valve plate material:
1. Valve plate: nylon plate, cast steel, stainless steel (304,316, 304L,316L), ductile iron plating (plating plate), UPVC, CPVC, PP, aluminum bronze (commonly used in seawater desalination), bidirectional steel 2507, duplex steel 1.4529
Third, valve seat material: valve seat: EPDM, PTFE, NBR, VITON
1. EPDM: black, soft seal, temperature: -15 to 85 ℃
Performance: oxidation resistance, ozone resistance and corrosion resistance, but easy to age in case of oil
2. NBR (nitrile rubber): NBR has excellent oil resistance, its oil resistance is second only to polysulfide rubber and fluororubber, and has excellent wear resistance and air tightness.
3. PTFE (polytetrafluoroethylene, commonly known as plastic king): white, soft seal, temperature: -20 ° C to 150 ° C Performance: heat resistance, wear resistance, corrosion resistance, non-sticky, relatively hard, generally powder, particles can be
4. VITON: black, soft seal, temperature: -15 ° C to 200 ° C, good chemical stability, excellent high temperature resistance (fluorine rubber high temperature resistance and silicone rubber), good aging resistance
5. Silicone rubber: In addition to strong alkali, hydrofluoric acid does not react with any substance *** tasteless, chemically stable, mostly used in the health food industry.
