4 ONSTRUTION Housing Hard anodized Aluminum casting and external epoxy powder coated against severe industrial environment. External mechanical stopper Prevents over run of travel angle when limit switch fails. able entries Standard P/4"(Max ") for various cable gland. Gearing Precisely machined double worm gear c/w minimum backlash, low noise, high output torque. Self locking Provided by double worm gearing to keep position of valve unchanged against reverse torque from valve. Sealing Removable drive bushing mounting base By Oring in all interfaces IP67(standard), and double oring for IP68 (option) Handwheel Different sizes depending on actuator torque, and knob on handwheel for easy operation. Motor aptive cover bolts Designed to prevent losing it during maintenance or installation. * All external bolts are stainless steel for rust prevention. Specially designed induction motor to generate high starting torque and high efficiency equipped with thermal protector to prevent damage from over heating. Insulation class Tapered interface between cover and lower housing or easy lifting cover up from lower housing for wiring or maintenance. Standard: Short interface for providing easier access to internal component Explosion proof : Long interface for keeping the length of flame path Standard short Optional long (Explosion proof) 4 I Pratt Industrial
