Bombay engineering industries manufactures gear operators in robust construction and materials selected for high product performance. The worm wheel of these gear operators is made of sg iron/phosphor bronze enabling high torque transmission. The gear operators are available with alloy steel worm having adequate strength thereby achieving lesser input-torque. Self-locking is ensured by the unique design of worm and worm wheel pair. The company also provides adjustable stopper bolts for precise valve positioning.
