ZS-300 Protective Housing NEMA 4X, stainless steel, corrosion resistant enclosures for AM, GM, AF, and NF actuators
The ZS-300 (-1) NEMA 4X enclosures may be used with GM, AM, AF, NF and LF Belimo actuators. They are intended for use primarily to provide protection against corrosion, windblown dust and rain, splashing water, hose-directed water; undamaged by the formation of ice on the enclosure. Type 304 stainless steel enclosures resist moisture, dust, salt, and corrosive chemicals, and are easy to keep clean for sanitary applications.
The ZS-300 enclosures are designed so that the required actuator may be easily mounted in the enclosure. The operating shaft and coupling are inserted from the backside through the rotating shaft seal. The actuator is fastened on the end of the operating shaft and secured at the end with an anti-rotation strap. Adjustable mounting brackets, if supplied, are assembled to the fixed mounting holes at the top and bottom of the enclosure with stainless steel nuts, bolts and lock washers. The direct drive coupling is designed for a 1/2” round or hexagonal shaft and secured with two square head set screws. Mounting brackets are adjusted and secured in place.
