l Applicable area adheres to IEC 721-3-3 (Regulation 721-3-3 by International Electro-technical Commission ) Grade 3K5

l Environmental temperature: -5…+50°C

l Valve inner medium temperature: +2…+130°C

l Using installation fittings ASK30 can drive the following 4mm or 5.5mm turn valves: X3i…, WG45…, VXG45…, VXG46… and VVI51…

Function Three-position or ratio control signal

Revisable synchro motor adopts three-way control signals (SQS35 and SQS85) or ratio control signal DC 0…10V (SQS65 and SQS65.5) or DC 2…10V (SQS65.2) for driving. It makes corresponding valve way through anti-lock gear mechanism.

Three-position control of Terminal Y1or Y2:

l Y1 has voltage: valve rod contracts and valve gate opens

l Y2 has voltage: valve rod extends and valve gate closes

l Y1 or Y2 has no voltage: valve rod keeps in current position

SQS65…       Flow Characteristics Selection

Repositioning connection S1 (under cap/under print circuit board) can change the flow characteristics of 5.5mm turn valve (from “equal proportion” to “linear”). In any case, flow characteristics relate to valve way.

l S1 connecting A and C can produce equal-proportion flow characteristics (factory set), which is mainly used for heating application.

l S1 connecting B and C can produce linear flow characteristics, which is mainly used for cooling application.

l For automatic operation, S1 connecting A and C or connecting B and C mainly depends on necessary flow characteristic.
