Product information
Nucom Series
	The actuators are capable of continuous positioning of valve opening with direct 4-20mA signals from a controller or computer. The actuators feature a far higher precision (Resolution 1/250) than those of traditional pneumatic types. With the robust and maintenance-free structure, they help you sharply save running cost.
(Features) Compact and lightweight. High resolution. (more than 1/250) Direct or reverse direction may be optionally preset at selection switch. An action mode (Close, open or stop) while signal interruption may be optionally preset at selection switch. Perfectly resin molded control servo pack for water/vibration protection. Helps simplify flow lines and equipment work. Saves running cost one over dozens compared with pneumatic types. Thermal protector in-fitted against motor burn-out. Water protection: NEMA-4, 4X Manual override with crank handle. (standard accessory)
Unic Series
	These are On-off type valve actuators. They are also operable at an intermediate position. With the robust, compact and lightweight die cast aluminum body, they feature high performance and high output.
(Features) Compact and lightweight. Easy of handling, also convenient for use even in a narrow space. Trouble-less simple structure. Easy of mounting, maintenance and inspection works. Manual override with crank handle. (Standard accessory) Thermal protector in-fitted against motor burn-out. Easy of wiring work with terminal block. Water protection: NEMA-4, 4X Global standards (UL, CSA, CE)		Declutchable handwheel
ESD Series (with Emergency Shut Down function)
	These are Battery back up rotary type actuators to be operated by external contact signals or by changeover of power source. Even in case of power failure, the actuator are operable of open-close action with external control. It also features Emergency Shut Down (open) function.
(Features) Super high speed (0.7 seconds max.) for open or close. Operable more than 100 times (open/close) during power failure. Instantaneous shut down (open) when power is failed. Universal voltage application. (85VAC~240VAC, 110VDC~240VDC) Water protection: NEMA-4, 4X
EXL Series (Explosion proof)
	These are the linear type electric actuators certified as in compliance with Explosion proof Standards (Exd II BT4). Available with Unic type-to be controlled by external contact signals or by switchover of power source, and Nucom type- to be controlled with computer or controller signals (4-20mA.DC).
(Features) Light and compact. Trouble-less simple structure. Easy mounting, maintenance/inspection work. Manual override by crank handle. (Standard accessory) Thermal protector in-fitted against motor burn out. Terminal block for easy wiring work. Explosion proof structure- Withstanding internal explosion and no ignition with internal flame on external gas or vapor.
