SAILTOR SIML-201 China Open-Close Linear valve actuator 

I. Product Overview

l  SAILTOR products and performance is world advanced level intelligent non-intrusive electric actuators which can be commissioned without removing covers. Users only need to setup once at both FULLY OPEN and FULLY CLOSE positions if there is no special requirement.

l  The product is composed of electromotor, gearbox, T shape screw nut as linear thruster, control box integration, manual handel, local digital display, local operation buttons etc. 

 l  It can apply to various control valves.      

 l  Small size and light weight. (1/3 of comparable products) It is especially suitable for small size ball valves and butterfly valves in limited, frequent vibrating space.

l  SAITLOR has wide range of product line: we offer On-Off duty, pulse control and 4~20mA modulating duty.. 

l  Power supply: single phase 220V/AC, 3-phase 380V/AC

l  Thrust range: 1000N~25000N

l  Protection Level: IP67  EX level: dIIBT4 

II. Main Features

l  Electrical control box is double-sealed enclosure largely increase the reliability and service life by avoiding damages to the circuit board if the control box is uncovered or water leaking into wiring holes.

l  We isolate electrical control box from installed electromotor so that the heat from the motor does not influence the circuit. Therefore, the actuator can operate normally in relatively high temperature environment.

l  Electrics double protection: The peripheral protection circuit shut off the main power when main control weak current system is malfunctioned. Therefore, it avoids damages to the actuators and the valves.

l  We avoid the trouble of battery lose no matter if the power is on by removing battery in actuators; therefore, completely avoid the setup change due to manual operation under power outrage.
