Product description

Valves of type DBDH…XC…E are type-examination tested, direct operated pressure relief valve according to Pressure Equipment Directive 2014/68/EU. They are used for limiting a system pressure and are intended for use as safety valves.

If the pre-set response pressure at the channel P is exceeded, the valves respond and internally connect channel P and channel T. Depending on their variant, the valves are designed as screw-in cartridge valve (“K”) for screw-in in block designs, as valve with threaded connection (“G”) or as valve for subplate mounting (“P”).

The actual screw-in cartridge valve used in all variants basically consists of sleeve (7), spring (6), poppet (5.1, response pressures up to 400 bar) or ball (5.2, response pressures from 405 bar), valve seat (4) and the adjustment element (8).

The spring presses the poppet (5.1) and/or the ball (5.2) onto the valve seat (4). At the factory, the response pressure is set to a fixed value using the adjustment element; afterwards, the valve is sealed.

The channel P is connected to the system. The pressure existing in the system acts on the poppet and/or the ball.

If the pressure in the channel P increases above the value specified by the preload of the spring, the poppet and/or the ball is lifted off the valve seat against the spring force and connects channel P and T. The hydraulic fluid flows from the channel P into the channel T. The maximum possible stroke of the poppet is limited by structural measures.

The valves are available with graded response pressures (in 5 bar steps). The valve spring can be unloaded by means of the hand wheel and a response pressure lower than that of the factory setting can be set without the need of removing the lead seal. See operating instructions.

Notes:

  • Value pairs located in the areas of the characteristic curves with gray background can not be realized with the valve.
  • The characteristic curves shown here are only valid for a counter pressure of 0 bar in the discharge line.

Counter pressure in the discharge line

Basically, the valve should be operated without counter pressure in the discharge line, if possible. With counter pressure in the discharge line, the maximum flow possible is reduced. There is a relation between the maximum counter pressure pT in the discharge line and flow qV, which can be seen from the following characteristic curves. Characteristic curves for intermediate values of the response pressure which are not listed must be determined by means of interpolation.

With a flow approaching zero, the maximum counter pressure pT is in each case 10 % of the response pressure. With increasing flow, the maximum counter pressure pT is reduced.

Interpolation of intermediate values from the diagram

  • At the pT axis, mark 1/10 of the value of pA.
  • Determine the next lower and the next higher characteristic curve for this point. The point marked at pT divides the section between lower and higher characteristic curve on the pT axis with a certain percentage.
  • At the qVmax axis, divide the section between next lower and next higher characteristic curve in the same percentage as the section at the pT axis. From the zerocrossing on the qVmax axis determined in that way, draw a straight line to the value on the pT axis marked before.
  • Mark the system flow to be secured at the qVmax axis.
  • Read off the maximum counter pressure for this value using the line at the pT axis drawn before.

Determination of the maximum counter pressure

Example 1 (with already existing characteristic curve):

  • Flow of the system / accumulator to be secured: qVmax = 115 l/min
  • Safety valve set to: pA = 315 bar.
  • Read off the maximum counter pressure pT of approx. 22,5 bar from the diagram (see arrows, Size 6, characteristic curve 7).

Example 2 (with interpolated characteristic curve):

  • Flow of the system / accumulator to be secured: qVmax = 15 l/min
  • Safety valve set to: pA = 80 bar.
  • Value to be marked at the axis referred to as pT: 1/10 x 80 bar = 8 bar.
  • Read off the maximum counter pressure pT of approx. 3 bar from the diagram (see arrows, dashed characteristic curve).

Information

Component marking

Type-examination tested safety valves bear a coded component marking. It always comprises the identical elements, the meaning of which is shown in the following example:

TÜV . SV . 13 - 390 . 4,5 . F . 30 . 500

Mark of the notified body which has carried out the type-examination procedure

TÜV

Safety valve

SV

Last digit of the year of the last extension of the validity of the component marking

13

Number of the component marking assigned by VdTÜV

390

Smallest flow diameter in front of the valve seat in mm

4,5

F

Maximum flow in l/min without counter pressure in the discharge line or discharge coefficient

30

500

Important information regarding the operation according to the Pressure Equipment Directive 2014/68/EU

  • Before ordering a type-examination tested safety valve, it must be observed that for the desired response pressure p, the maximum admissible flow qVmax of the safety valve must be larger than the maximum possible flow of the system/accumulator to be secured. In this respect, the applicable regulations must be observed!
  • According to the Pressure Equipment Directive 2014/68/EU, the increase in the system pressure due to the flow must not exceed 10 % of the set response pressure (see component marking). The maximum admissible flow qVmax stated in the component marking must not be exceeded. Discharge lines of safety valves must end in a risk-free manner. The accumulation of fluids in the discharge system must not be possible (see data sheet AD2000 A2).

It is imperative to observe the application notes!

  • In the plant, the response pressure specified in the component marking is set at a flow of 2 l/min.
  • The maximum admissible flow stated in the component marking applies for applications without counter pressure in the discharge line (port T).
  • By removing the lead seal at the safety valve, the approval according to the Pressure Equipment Directive becomes void!
  • Basically, the requirements of the Pressure Equipment Directive and of data sheet AD2000 A2 have to be observed!
  • It is recommended to secure type-examination tested safety valves against inadmissible removal from the screw-in housing/block by means of wiring and sealing with the housing/block (bore available in the adjustment element).

Notice

The system pressure increases by the counter pressure in the discharge line (port T) due to the increasing flow. Observe data sheet AD2000 A2, point 6.3!

To ensure that this increase in system pressure caused by the flow does not exceed the value of 10 % of the set response pressure, the admissible flow has to be reduced dependent on the counter pressure in the discharge line (port T) (see characteristic curves).
