9.1.3 DESCRIPTION

Valves DBDS type are pressure direct command relief valves. Their fun-

ction is to limit the pressure of a hydraulic system. The calibration of the

system pressure is carried out continuously through the calibration de-

vice, which, by the spring, pushes the wedge against the seat.

The P channel is connected to the pressure line of the system, entering

the valve, and acts on the active area of the wedge (or of the ball for the

DBDS 10 at 630 bar).

When the pressure in channel P exceeds the value set on the spring,

the wedge or the ball raises in contrast to the spring. The fluid now flows

from the channel P to the channel T. The stroke of the wedge is limited

by a pin in the damping chamber.

To obtain a good resolution of the pressure setting from 0 to 400 (630)

bar, this has been divided into 7 pressure ranges. Each range has a spe-

cific spring for adjusting a maximum working pressure.

9.1.4 STRUCTURE

Body: in high strength steel, obtained by mechanical processing, in

which are obtained the seats.

Poppet: obtained by mechanical processing from bar, it ensures the ne-

cessary seal degree on the valve seat. The poppet is well led by the dam-

ping piston and pushed by the spring against the seat.

Spring: it counteracts the pressure and the dynamic actions of the fluid

and always ensures the closing of the valve after the discharge. The

coils of the spring, even when the obturator has reached its maximum

ift, are never at pack.

The poppet has a mechanical lock and when it has reached it, the arrow

of the spring does not exceed 85% of the maximum deviation.

Calibration system: threaded hexagon head screw which screws into

the top of the valve by compressing the spring below. After the calibration,

he position of the adjusting screw is kept unaltered by locking the counter

nut and sealing the adjusting screw (valve with EC/PED/EC certification).

.1.5 CALIBRATION

All valves are calibrated on the working bench with a flow rate of 2 l / min.

and with an atmospheric counter pressure. The repeatability error of ca-

libration is less than 3% than the pressure P. Up to a pressure equal to

97% of the calibration pressure verifyng that there’s no leackages.

.1.9 EUROPEAN MARKET

Directive 97/23/EC provides that pressure equipment, in which it's rea-

onably expected to be exceeded the allowable limits, should be provided

with adequate protective equipment; for example, safety accessories

such as the valves DBDS “G”/ DBDS “P” or the safety blocks type BS.

These devices shall prevent that pressure permanently exceeds the ma-

ximum allowable pressure PS of the equipment protected by them. Ho-

ever, it is permissible a pressure peak of short duration limited to 10%

of the maximum allowable pressure. For the choice and sizing of the

adequate safety device, the user should refer to specific standards.

In accordance with the regulations 97/23/EC, the safety valves are clas-

sified in Category IV.

Blocks for relief valves, see section 9.2

Safety blocks, see section 9.3

9.1.11 COMMISSIONING AND MAINTENANCE

Installing the valves

Regarding the installation of the safety valves, you should be kept in

mind the following key points:

- safety valves must be installed in correspondence of the area to be pro-

tected by any overpressures; the vessels, connected each other by ap-

propriate piping with a diameter adapted by the Manufacturer and User

and on which there weren't interposed the interceptions, can be consi-

dered for the installation of the safety valves as a single vessel;

- the connection between the valve and the equipment to be protected

should be as short as possible and must not have a cross section smaller

han the one of the valve inlet. In any case, the standard EN

13136:2001/A1: 2005 states that the pressure drop between the protec-

ted vessel and the safety valve, at flow rate of full discharge, should not

exceed 3% of the pressure value P, including any accessory inserted on

the line;

the choice of the safety valve displacement should consider that the

operation of the valve results in the discharge of the fluid under pressure

to be sent into the tank. The discharging pipe must be sized as not to

affect the operation of the valve. Standard EN 13136:2001/A1:2005 re-

quires that this pipeline should not generate, at full capacity, a pressure

higher than 10% of the value of the calibration pressure.

Disassembly

Before removing the valve, make sure that the system on which it is

mounted is not under pressure and that there is no pressure within the

valve.

Ordinary maintenance

Check the system in order to verify that there are no leakages of oil into

the tank, with overheating of the assembly.

Periodic retest according to the related standards of the country of in-

stallation. In Italy, see the Ministerial Decree 329 dd. 12/01/2004: for

fluids of the group 1: every 2 years you must carry out a functional test

and every 10 years you must check the integrity; for fluids of the group

2, every 3 years, you must carry out a functional tes and every 10 years

you must check the integrity.

See section 9.3.8

9.3.3 DESCRIPTION

The EPE range of safety blocks BS is available in sizes NG10, NG20,

NG25 and NG32. The safety blocks BS combine all the features to pro-

tect, isolate and discharge a hydraulic accumulator. The shut-off valve

rotates of 90 degrees to instantly isolate the accumulator from the hy-

draulic system in emergency conditions or for maintenance. Once iso-

lated, the accumulator can be discharged into a tank through a

discharging valve with manual or electric controls. In version BS10 and

BS20 when switching over the ball valve, the pump flow rate is stopped

and simultaneously the accumulator discharged to the tank. During swit-

ching all three ports (P, A and T) are momentarily interconnected (nega-

tive switching overlap). Ball valves are not designed to be used as flow

control valves; therefore they should always be either fully open or fully

closed, to avoid damaging the sealing cups. The system security is en-

sured by a pressure PED an anti-tempering pressure valve certified

CE/PED. The safety blocks BS allow easy and secure connection of an

accumulator to a hydraulic system. Suitable for use with all types of blad-

der, piston and diaphragm accumulators, the compact and multifunction

design allows saving space and reducing the wiring. By reducing the

times required by the procedures of installation and maintenance, the

security blocks BS help maximizing the productivity and profitability, mi-

nimizing the downtime of the system. For easy installation, we offer a

full range of adapters, suitable for all standard fittings of any size and

type. For diagnostic purposes and for continuous monitoring of pressure,

all the security blocks BS are provided with a manometer connection of

1/4"BSP. The European Directive on pressure equipment 97/23/EC sta-

tes that all accumulators must be provided with a safety device that in-

tercepts, limit and discharge the pressure as well as allows carrying out

the measurements. BS range satisfies all these requirements with a sin-

gle and compact device. The safety block should always be mounted

as close as possible to the accumulator.

.3.4 PRESSURE RELIEF VALVE

The function of the pressure relief valve is to protect the accumulator du-

ring its operation. If the pressure exceeds the valve setting, this opens

and discharges the fluid into the tank and allows the pressure in the sy-

stem returning to a safe level. Thanks to its cartridge design, the pres-

ure relief valve can be recalibrated to another pressure setting. This

change requires a new approval according to PED 97/23 EC. The ves-

sels discharge pressure expressed in bar, is stamped on the nameplate.

The pressure relief valve is controlled and carefully sealed after approval

in accordance with the rules of pressurized vessels. On their body there

are stamped the CE mark, the certification ID and the serial number. All

valves are supplied with a certificate attesting the calibration pressure.

The documents provided with the pressure relief valve must be kept as

they may be necessary in the event of repetition of the tests.

Manual and electric discharge valve

The discharge valve allows the discharge of the accumulator fluid in the

tank. All models of the safety block BS have a manually operated valve.

n addition to the manual valve on request, could be installed a dischar-

ging electrically-controlled valve.

.3.11 EUROPEAN MARKET

Directive 97/23/EC provides that pressure equipment, in which it's rea-

sonably expected to be exceeded the allowable limits, should be provided

with adequate protective equipment; for example, safety accessories

such as the valves or the safety blocks type DBDS or BS. These devices

hall prevent that pressure permanently exceeds the maximum allowable

pressure PS of the equipment protected by them. However, it is permis-

sible a pressure peak of short duration limited to 10% of the maximum

allowable pressure. For the choice and sizing of the adequate safety de-

vice, the User should refer to specific standards. In accordance with the

regulations 97/23/EC, the safety valves are classified in Category IV.
