CARGO TANK DEVICE
VOCON VALVE
General Description
SEWON vocon valve is an automatic pressure/vacuum valve developed to provide automatic pressure control by electrical actuator for the cargo tanks pressure, ensure that maximum acceptable pressure is not exceeded and to emission less excess VOC (Volatile Organic Compound) over the outside.

Operate system : Electrical
Design
The vocon system consists of vocon valve with an actuator, an automatic electric control panel and a pressure transmitter installed in the IG main line.
This system operates the vocon valve to regulate the pressure of the cargo tank and IG main line to discharge the inert gas to the atmosphere.
Open and close are adjusted according to the desired setting of the control panel.

Equipment components
Vocon Valve
Electric Control Panel
The vocon valve is operated from an PLC of the control panel.
Control panel has composed display panel, emergency button and manual switch, lamp, main power switch.
The control panel must be installed in a non-hazardous area.

Electric Actuator
Pressure TranmitterIt is installed on the IG main line and serves to transfer the line pressure to the control panel.Voltage : 24VDCExplosion proof : Exd IIC T6, IP67
The operation of the valve can be controlled in both automatic mode and manual mode.
The amount of VOC discharged through the vocon valve during the ship's sail is recorded.
