POPU Valve: Triple Eccentric Butterfly Valve
Triple eccentric hard seal butterfly valve is an energy-saving and long-life butterfly valve. Widely used in electric power, petroleum, chemical industry, metallurgy, municipal construction and other industrial pipelines, as a cut-off or regulate the flow of media.
The product adopts three eccentric structure, elastic seal and hard and soft multi-layer seal compatible processing technology, can make the butterfly valve in operation, reduce the torque force, to achieve the effect of energy saving, energy saving, to ensure that the valve's overall corrosion resistance, high temperature resistance, resistance to abrasion.

1. Valve body is all precision casting valve body, material WCB up to standard, fine appearance, no grits, each batch of castings are marked with furnace number, convenient for production tracking and material inspection.
2. Numerical control lathe processing butterfly plate, sealing ring for the soft and hard multi-layer stacked metal ring, with metal and elastic sealing of the double advantages, to ensure that in the high temperature, low temperature environment have excellent sealing performance.
3. The valve stem is made of stainless steel, and the strength of the stem is doubled after tempering treatment, which reduces the opening and closing and leakage problems caused by the deformation of the stem.
4. After the product is manufactured, each product is painted with lead-free paint for three times on the primer and top coat to ensure the brightness and rust resistance of the product appearance.
5. Products in the pressure and commissioning of the worm gear adjusting screws and then do processing, adjust the length of the right and left is consistent in the shipment, each product worm gear adjusting screws are equipped with a protective nut to protect the adjusting screws from damage.
6. From rough to finished products, packaging, delivery of each link layers of quality control.
