Seeking recommendations for long-life pneumatic actuators
Thread Content
Everyone, our company is currently looking for pneumatic actuators with a service life of 3 million cycles, for use with pneumatic butterfly valves in angular motion applications. Gas source pressure: 0.5~0.7, annual operation count: 1.5 million times (one operation per switch). At a torque of 5 bar and air pressure, the maximum value required is 0~4000 nm or more. I’m not sure if anyone has used cylinders with such a long service life; could you recommend some manufacturers and model numbers?
There are 86,400 seconds in a day – what kind of operating conditions require such frequent switching? ? ?
I’ve seen that many valves can withstand millions of cycles; high-performance eccentric butterfly valves are no exception； lpb13 pneumatic butterfly valve ； Soft-sealed eccentric butterfly valve ； Pneumatic SNJ butterfly valve ； lpb13 electric butterfly valve ； Electric SNJ butterfly valve: * This series of high-performance butterfly valves is primarily used in industries where gas separation is required and where high durability of the valve is essential. They feature reliable sealing and excellent flow performance, with a normal service life of up to millions of cycles. * It adopts a single PTFE seat design, which provides excellent elasticity and high sealing reliability; no additional O-rings or metal components are needed for sealing purposes. The lip-type sealing structure can compensate for the changes in temperature and pressure that affect the valve. The sealing test meets the standard of no bubble leakage in both directions. * The off-axis and eccentric butterfly valve design ensures that there is no contact between the valve seat and the valve disc when the valve is open or in the middle position; moreover, there are no wear points on the upper and lower parts of the valve seat, resulting in low torque requirements. * A fire-resistant version is available. * The valve seat is easy to maintain – it can be replaced simply by removing the insert, without the need to disassemble the valve disc or the shaft. * An actuator with a gear and rack mechanism is used; this type of actuator can operate for up to one million cycles, matching the lifespan of the valve, and requires no further maintenance
It usually switches on and off every 30 seconds...
Yes, imported Metso cylinders are available; feel free to contact me if you need them
Such a high frequency, pressure swing adsorption?
Are matching valves required? High-frequency switches can also ensure sealing.
Fan-shaped cylinders are suitable; they have a lifespan of 4 million cycles and are widely used in PDS valves
Our company’s fork-type cylinders can meet your needs; they are designed for high-frequency use and can maintain a service life of 2 million cycles. Example: In washing equipment, some imported brands have a shorter service life compared to ours. If you are interested, feel free to contact me at VX152900791221
