AKM 105S, 115S: Rotary actuator with SAUTER Universal

Technology (SUT) for ball valve

How energy efficiency is improved

Automatic adaptation to ball valve, precise activation and high energy efficiency with minimal operat

ing noise.

Features

• For operating 2- and 3-way ball valves VKR, VKRA, BKR, BKRA, VKAI, VKAA, BKLI, BKTI, BKTA,

(AKM115S) and 6-way ball valve B2KL

• For controllers with constant output (0...10 V) or switching output (2-/3-point control)

• Assembly with ball valve without the use of tools

• Stepping motor with SAUTER Universal Technology (SUT) electronic control unit

• Electronic force-dependent motor cut-off

• Automatic recognition of applied control signal (continuous or switched)

• Coding switch for selection of characteristic and running time (35 s, 60 s, 120 s)

• Type of characteristic (linear/quadratic/equal-percentage) can be set on the actuator

• Direction of operation can be selected directly on the cable

•Maintenance-free gear unit

• Gear unit can be disengaged in order to position the ball valve manually (using the lever)

• Bracket and bayonet ring made of glass-fibre-reinforced plastic for fitting onto ball valve

Description of operation

Depending on the type of connection (see connection diagram), the actuator can be used as a contin

uous 0...10 V, 2-point (OPEN/CLOSE) or 3-point actuator with an intermediate position

(OPEN/STOP/CLOSE).

The running time of the actuator can be set with the coding switch according to requirements. The

coding switch can be used to select the equal-percentage, linear or quadratic characteristic. The

AKM 115 is combined with ball valves that have an equal-percentage basic characteristic like the

VKR or BKR.

The manual adjustment is performed by releasing the gear unit (slide switch beside the connection

cable) and simultaneously turning it with the lever. The actuator position can be determined by look

ing at the lever or the indicator knob on the top part of the actuator
