NIPPON GEAR

Valve actuator

B series

Outline

B series bevel gear actuators are designed for multi-turn operation. The actuator is available for rising stem type gates and valves which need a thrust load to open and close.

Features

  • – The actuator can be easily operated with its hammer blow effect.
  • – The actuator consists of rolling bearing design and has an efficiency in excess of 90%.
  • – Due to two-piece drive sleeve configuration, its stem nut engaged with a valve stem can be easily removed out from the actuator.
  • – This actuator is of enclosed construction, filled with “EP” additive grease and ready for use.
  • – The actuator is available with local position indicator.
  • – The actuator can be coupled to actuators such as SMB, JMB or L120.
  • – Dual input shaft type is available, so it makes the actuator easier in a wide variety of demanding applications.
  • – B series has 8 unit sizes classified by output torque.
