STTC-MV32-24VS : Motorized electric valve (servo) 1 1/4″ (DN32), NC, 24VAC, AISI 304

The STTC-SM32-24VS is a 24V (AC 50Hz/60Hz) electric motorized valve DN32 made of stainless steel for one cooling channel. It is used for a quick opening and closing of the coolant pipe way of the one tank cooling zone. Each the motorized  valve is connected to the STTC-CB100 connection box. Threads DN32 (G 1 1/4″) pipe connection . Designed in Czech republic.

When the valve is activated (ON state), then it opens in 6 seconds. Then the valve doesn´t  consume electric current. When the valve is disconnected from the electric voltage then internal electronics recognize it and it automatically closes the valve in 6 seconds – the internal battery powers the motor.
