Environment and installation

Installation

As required, preferably with actuator upright

Ambient temperature

FFKM

+ 15 °C…+ 50 °C (59 °F…122 °F)

FKM

0 °C…+ 50 °C (32 °F…122 °F)

EPDM

0 °C…+ 50 °C (32 °F…122 °F)

FFKM HCR

+ 15 °C…+ 50 °C (59 °F…122 °F)

1.) The service life depends on the medium, temperature, pressure, sealing material and individual operating conditions.

2.) May be higher with impulse version. < 20 dB(A) with optional soft-close electronics only possible in conjunction with standard valve.

3.) Measurement at 2 bar and + 20 °C at the valve outlet acc. to DIN ISO 12238:2001

4.) Max. housing temperature must not exceed 110 °C. In continuous operation care must be taken to ensure sufficient heat dissipation (convection) at the metal surface of the

valve. Overheating of the valve can lead to damage.

5.) No further power reduction possible

6.) Reduced shifting performance at 15 °C

7.) Please order socket with flying leads separately (see “7.4. Ordering chart accessories” on page 13).

Other suitable connectors are, for example W+P: Series 521 (socket 521S- 02 - 1; contact 521S- 01 - 2 - 00) or JST (socket PHR- 2; contact SPH- 002GW-P0.5S), version

04/2015). As a PCB connector we recommend a pin size of 0.5 x 0.5 mm, grid size 2 mm and a maximum size of the connector of 4.9 x 2.5 mm. E.g. Samtec SQT- 102 - 01-

x-S (x=L or F) or W+P Series 257 Part No. 257 - 002 - 1 - 50 - 00 - 6.

1.) Connect technical vacuum (- 0.8 bar) to NC or NO. If vacuum is connected to (COM/OUT), significantly reduced flow must be expected.

2.) Up to 2 bar, the flow direction is permissible even against the specification.

3.) Low vacuum due to back pressure at media flow permissible. In case of continuous operation with higher vacuum, there is a risk of flow reduction. In case of doubt, please

contact your Bürkert sales office.

4.) For information on the optional boost electronics see chapter “7.4. Ordering chart accessories” on page 13.
