Solenoid Valve Cabinet - SVC

A SVC is designed to suit customers’ requirements as it houses both the

hydraulic and the electrical section.

Control signals are received from the control switches to activate the

solenoid valves to control the direction of oil flow to each actuator.

The electrical section is designed with IP44 protection class. It can also be

build with the PLC remote I/Os and other system processing capability.

SVC range:

- SVC 32 (controls up to 32 actuators)





The SVC must be installed in a safe, non-

hazardous location onboard the vessel.

Technical Data


Test Pressure 202.5 bar

Pipe Connection ¼” BSPP

Weight of 4-station 4kg

Weight of 6-station 6kg

Weight of Top Block 2kg

Weight of Bottom Block 1kg

Material Aluminium 606IT6 Anodizing

The purpose of the VFM is to provide the

feedback of the valve position by measuring

the volume of oil in the actuator.

Components

Throttle valves are used to control the

travelling speed of the valve.

The pressure switch is used for on/off valve

feedback indication.

It is a low cost mechanical pressure switch with

high overpressure resistance and a long

working life under harsh conditions.

It operates at a pressure setting of 15/100

bars.

It is used for directing and stopping flow at

any point in a hydraulic system.

Types of hydraulic solenoid valves:

- 4/2 way, detent type, double coil (I.S &

non-I.S)

- 4/2 way, spring return, single coil (I.S

& non-I.S)

- 4/3 way, spring centre, double coil

Volumetric Flow Meter

Manifold arrangement for the control of hydraulic actuators is designed in modular

blocks.

- 4-station arrangement

- 6-station arrangement

- Maximum of 30-station per column

The connection between each modular block is by adaptor plates for easy

installation coupled with reliable sealing that prevents leakages.

Each control station consists of 2 throttle valves. It is used to

- control the travelling speed of the valve

- isolate the control station during servicing of that station without the need

to shut down the entire system.

Top Block

Consists of:

- pressure guage (for main pressure reading)

- by-pass valve (closed during normal operation, open during system

commissioning or to bleed air in the hydraulic system)

Bottom Block

Consists of:

- 2 quick connection (for portable hand pump)

- 2 ports

- P & T with ¼” BSPP connections

- 2 stop valves (for complete isolation of P&T for servicing or emergency,

used together with portable hand pump)

Main Block (4-station)

Consists of:

- 4 stop valves


- 4 P & T with ¼” BSPP connections

Main Block (6-station)

Consists of:

- 6 stop valves


- 6 P & T with ¼” BSPP connections

Manifold Arrangement

Volumetric Flow Meter – VFM

The VFM is a precision gear motor with a visual display indicating the valve

position by measuring the oil volume in the actuator.

It is integrated with a gear type volume counter and visual indicator.

- The visual indicator is equipped with 2 end stopper to limit the arrow

pointer for adjustments from fully open to fully close.

The gear box for each application achieves a local pointer movement

indication of 210° for valve positioning.

Types of VFM:

- VFM-E: Visual + Electrical open/close

indication (on/off function)

- VFM-C: Visual + Electrical analog -

potentiometer (modulating function)

The turning movement of the magnetic drive is

integrated with an indicator to:

- recognize the flow direction of the

hydraulic oil

- act as a leak indicator

Hydraulic Power Unit - HPU

The HPU is used to generate the required pressure to operate the whole

actuation system.

It is designed for easy access to internal components so that repairs and

testing can be done efficiently. It is compact and built on a standard modular

platform.

In the event of a power failure, a backup pressure from the accumulator will

support the whole valve system. Thus, allowing the operation of the ships’

critical valves.

HPU consists of:

- Starter control panel

- Oil tank

- Electric motors

- Hydraulic pumps

- Pressure gauges

- Pressure switches

- Temperature control switch

- Oil sight glass

- Inspection/maintenance cover

The EA has a robust and compact construction that provides a high output

torque – 9000Nm. It has hard anodized aluminium housing with external power

coating for severe industrial environment.

The enclosure uses radial seals & O-rings that provide protection to waterproof

IP67 (Nema 4&6) and optional watertight IP68. The Reliable Mechanical Toque

sensing system provides safe operation in overload conditions.

Various local position control options are available to provide easy

commissioning and operation in the field. The large window and the presence

of an indicator give superior position indication from a distance.

The Air Bubbling Sensor is a pneumatic gauge designed to measure the liquid

level of tank with electric output. It is a pneumatic-electrical type transmitter.

It is based on the principle of “bubbling” that is well known for its sturdiness and

reliability. A fixed flow of air is passed through a tube with an opening below the

surface of the liquid level. Pressure in the tube is proportional to the depth (and

density) of the liquid over the outlet of the tube. Pressure signal is then either

displayed through pressure gauge with level scale or converted to electrical

signal (mV or 4-20mA) through a pressure transmitter.

Air Bubbling Sensor

It consists of three main parts:

• An air modulator, designed to detect pressure generated by the liquid

height when compressed air is injected into the tank pipe

• A PCB, converts the measured pressure into an mV or a 4-20mA signal

• An air purge, directly mounted on top of the tank, including a non-return

valve

It is suitable for measuring the level of sewage, drainage water, sewage

sludge and water with large quantities of suspended solids. It is a good

choice for classified “Hazardous Areas”. Due to of its purge function, this

transmitter is considered as inherently “self-cleaning”. Air bubbling

transmitter is highly recommended for liquid level measurement for those

applications where ultrasonic, float or microwave techniques have proved

undependable.

The compressed air can be supplied from the main air utility via a reducing

valve or by using a miniature compressor.

Technical Data

Radar Type Sensor

DMH carries two kinds of radar type sensors.

The VEGAFLEX 66 is a level sensor for measurement of liquids and bulk solids at

high pressures and temperatures. It delivers reliable and high precision

measured values unaffected by ambient influences such as dust, steam, build-up

and condensation.

The VEGAPULS SR 68 is a radar sensor for continuous measurement of bulk

solids even under difficult process conditions. It is particularly suitable for level

measurement in high silos and large bunkers.
