The main characteristics:
1 Small in size and light in weight...Easy installation and maintenance. It can be mounted wherever needed.
2. Simple and compact construction, quick 90 degree on-off operation.
3. Minimized operating torque, energy saving.
4. Flow cure tending to straight line. Excellent regulation performance.
5. Long service life. Standing the test of tens of thousands opening/closing operations.
6. Bubbles-tight sealing with no leakage under the pressure test.
7. Wide selections of materials, applicable for various medium
8. Stem and disc are connected by means of pinless structure with more reliable performance.
9. Disc seat and body of non backed slim-disc butterfly valve are connected by frameless structure to overcome leakage on the connecting position of flange sealing surface.
Application:
1. These products are mainly used for pipeline flow, pressure and temperature control of various industrial automation productiong, for example: Electricity, petrifaction, metallurgy, environmental protection, energy management, fir-fighting systems.
2. Simultaneously they have good fluid control properties, and can operate simply.
3. They are not only widely used in general industries as petroleum, coal gas, chemical engineering, water treatment, but also used in the cooling water system of thermal power plant.
Packaging Detail: Inner packing: Individual polybag for each valve Outer packing: Plywood box~veneer case, standard size is 1150*950*550mm/1150*950*600mm We can also make the case according to consumer's requirement or the real size of valves.
Note:
1. All of our butterfly valves are backed by 24 months guarantee.
2. We can match the different rubber ring according to the different medium conditions, such as NBR, PTFE, CSM, EPDM, CR, Viton and other rubber materials.
3. We can match different materials about body, plate and stem, such as ductile iron, cast steel, stainless steel 304, 316, 316L according to special working condition.
4. If the valve leakage after 24 months service, just remove handle then add a bushing to prevent leakage, need not disassemble the valve or change a new one, very economic.
