Design and principle of operation

3 Design and principle of oper-ation

Î SeeFig. 3-1TheType 33-7ExcessPressureValve(SEV)consists of the main valve with actuator and the pilot valve attached to it.Thesafetyexcesspressurevalveisusedtomaintain the pressure upstream of the main valve to a set point adjusted at the pilot valve.Thesafetyexcesspressurevalveopensastheupstream pressure p1 rises.Whenthesafetyexcesspressurevalvestartstoopen,theprocessmediumfirstflowsthrough the pilot valve (8) before the main valve(1)opens.Duringwhich,theforcesacting on the plug in the main valve are eliminated by the balancing bellows (5).The upstream pressure p1 is fed through the control line (10) to the pilot valve (8). The pilot valve (8) creates a control pressure pS. It functionsasanexcesspressurevalveandcontrols the main valve (1).The control pressure pS is transferred through the control line (12) and acts on the operat-ing diaphragm (6).The control pressure pS drops when the upstream pressure p1 rises. The force resulting from the control pressure pS acting on the operating diaphragm (6) and the forces created at the positioning springs (7) fall below the force of the prevailing upstream pressure p1. The main valve (1) opens.

A decrease in upstream pressure p1 causes the control pressure pS to rise. As a result, the control pressure pS gradually reaches the same level of the upstream pressure p1 causing the main valve (1) to be closed by the positioning springs (7).Upon failure of the operating diaphragm (6), thesafetyexcesspressurevalveopensandthe pressure falls below the adjusted pres-sure p1.

To ensure proper functioning of the regulator, the minimum differential pressure Δpmin must correspond to the pressure specified in Table 3-1.

5.1 Installation conditionsWork positionThe work position for the regulator is the front view onto all operating controls on the regulator(includinganyadditionalfittings)seen from the position of operating person-nel.Plant operators must ensure that, after instal-lation of the device, the operating personnel can perform all necessary work safely and easily access the device from the work posi-tion.

Pipeline routingThe inlet and outlet lengths vary depending on several variables and process conditions and are intended as recommendations. Con-tactSAMSONifthelengthsaresignificantlyshorter than the recommended lengths.To ensure that the regulator functions proper-ly, proceed as follows:

Î Observe the inlet and outlet lengths (see Table 5-1). Contact SAMSON if the reg-ulator conditions or state of the medium process deviate.

Î Install the regulator free of stress and

with the least amount of vibrations as possible. Read information under ‘Mounting position’ and ‘Support or suspension’ in this section.

Î Installtheregulatorallowingsufficientspace to remove the actuator and valve or to perform service work on them.

Mounting positionTo ensure that the regulator functions proper-ly, proceed as follows:

Î Install the regulator with the actuator sus-pendeddownwardinhorizontalpipe-lines(seeFig. 5-1).

Î Makesurethedirectionofflowmatchesthe direction indicated by the arrow on the body.

Î Contact SAMSON if the mounting posi-tionisnotasspecifiedabove.

Damage due to freezing.Protect the regulator from icing up when con-trolling media that can freeze. Unless the regulator is installed in locations where no frost occurs, remove the regulator from the pipeline when the plant is shut down.

Do not install any instruments (e.g. tempera-ture regulators or shut-off valves) that restrict the cross-section of the pipe between the pressure tapping point and the regulator.

5.4 Testing the regulator

Risk of bursting due to incorrect opening of pressurized equipment or components.Regulators and pipelines are pressure equip-ment that may burst when handled incor-rectly. Flying projectile fragments or the re-lease of process medium under pressure can cause serious injury or even death.Before working on the regulator:

Î Depressurize all plant sections concerned and the regulator.

Î Drain the process medium from all the plant sections concerned as well as the valve.

Re

Risk of personal injury due to process medium escaping.

Î Do not start up the regulator until all parts have been mounted.

Risk of hearing loss or deafness due to loud noise.Noise emission (e.g. cavitation or flashing) may occur during operation caused by the process medium and the operating condi-tions.

Î Wear hearing protection when working near the regulator.

DANGER!

DANGER!

WARNING!

Risk of burn injuries due to hot or very cold components and pipelines.Depending on the process medium, valve components and pipelines may get very hot or cold and cause burn injuries.
