Stainless Steel Pulse Valves Take Filters to Cleaners

Aluminium does not always meet the requirements imposed on the materials of valves used in dust cleaning systems. Buschjost has supplemented the 82900 and 82960 filter pulse valves with stainless steel models specifically designed for such cases. The new 83300 and 83320 series now provide alternatives suitable for use in mining, the food industry and aggressive environments. Coming in nominal diameters of up to G 1 1/2, they ensure rapid, efficient and thorough cleaning of the filters. All of the valves in the series may be indirectly actuated pneumatically or with a solenoid.

For ease of installation, even in tight spaces, the Buschjost designers have provided a simple, twist-on bayonet connection between the valve body and the solenoid, all of whose components are captive to avoid getting lost.

The bodies are optimised to achieve the fast opening, optimised peak pressures and high air flows demanded for effective cleaning. With a G 1 1/2 connection the Kv value is 59m3/h. All of the valves in the series are also fitted with a silencer. This reduces noise to the extent that the valves can even be located close to the production area. The newly developed diaphragm guide provides reliable operation in all ranges and a long service life. Solenoid pilot actuation offers maximum protection against icing. The standard valves operate at fluid temperatures between -40 und +85 degrees, and special models at up to 140 degrees Celsius. The filter pulse valves are designed for a pressure of 0.4 to 8 bar.

All of the valves of the 82960 and 83320 series, from G 3/4 to G 1 1/2, operate with the same interchangeable solenoid system. DC and AC versions are available for all of the common voltages from 12 to 230V. There are also a large number of solenoids with special approvals, such as ATEX and UL.
