Overview
Electric double eccentric butterfly valve is further improved on the basis of single eccentric butterfly valve. Its structural feature is that the axis of the valve stem deviates from both the center of the butterfly plate and the center of the body. The double eccentric effect enables the butterfly plate to quickly detach from the valve seat after the valve is opened, greatly eliminating unnecessary excessive compression and scratching between the butterfly plate and the valve seat, reducing the opening distance, reducing wear, and improving the service life of the valve seat. The significant reduction in scratching and the adoption of metal seats for double eccentric butterfly valves have also improved their application in high-temperature fields.
Product Details
In an era where price competition has reached a white hot level, many companies have lost their price and quality bottom lines in order to accept orders. However, our company is one of the few valve manufacturers that does not compete on price, adheres to our original intention and bottom line, and steadfastly pursues the path of high quality.
Everything we promise to provide is always a high-quality product that ensures you have no worries. If we are not 100% certain, we would rather give up. So, between sticking to the bottom line and making choices, we have gained a large number of Fortune 500 corporate clients who trust us deeply and have long-term cooperation with us.
If you are looking for a supplier that can provide long-term cooperation, peace of mind, and peace of mind, please contact us. If your goal is to find products with ultra-low prices, we may not be suitable for you.
Regarding our company's RUNFLOWElectric double eccentric butterfly valveThe characteristics of the products are listed as follows:
Product advantages
What are the characteristics of RUNFLOW centerline butterfly valve compared to other valve products?
1. The valve shaft has undergone special dust-proof design
2. The entire series is equipped with a static conductivity guiding device structure
3. Selection of soft and metal valve seats;
4. Standard materials A216 WCB, A351 CF8, A351 CF8M. For other special materials, please consult our company separately
5. Bidirectional pressure holding design
6. The company is equipped with rational and mechanical performance testing equipment, valve performance testing equipment, ball accuracy tester, and valve life test bench to ensure the stability of product quality.
Electric actuator
Our NOAH Korean imported electric actuator features:
After surface oxidation treatment, the sealed alloy shell has strong anti-corrosion ability, and the shell equipped with sealing rings meets waterproof standards such as IEC IP67 and NEMA4~6. In addition, there is an explosion-proof device designed inside the shell, which can be suitable for work under any environmental conditions.
Unidirectional and three-phase power supply are standardized in one module, and composite terminal blocks can fully meet requirements such as DCS auxiliary connectors, interlocking, and other phase selection.
The arrangement of mechanical components and electronic modules can be easily removed, thereby improving the conditions for assembly, maintenance, repair, and replacement of electrical components. There is sufficient space inside the electric actuator to provide installation of optional components.
The size design of the handwheel ensures safety and labor-saving during manual operation
Manually operate the clutch lever, and after the clutch is disengaged, the handwheel can be turned. When powered on, the clutch will automatically reset.
The installation base complies with the ISO5211 standard. The transmission shaft sleeve can be disassembled and machined to the size required for valve spindle assembly. The position of the electric actuator can be adjusted by the four screw holes on the transmission shaft sleeve.
The dryer installed inside the electric actuator can prevent condensation caused by temperature and weather changes. A standard 20W dryer can keep all electronic components inside the actuator dry and clean.
The limit switch is controlled by a simple and reliable cam mechanism driven by the spindle. The valve position is adjusted using this simple and adjustable switch, and the valve position adjusted by it is not affected by whether it is "excessive" or not during manual operation.
The torque switch with cam action is easy to adjust and provides "overload" protection.
The self-locking function between the worm gear made of high-quality steel and the worm wheel made of copper green aluminum alloy can prevent reverse rotation under input control signals or power outages.
