– with tube connection both ends: RHD
– with tube connection
to male stud: RHV/RHZ
– with female thread both ends: RHDI
– valve cartridges: RVP
– valve internal parts: I-TL
– leakage rate hydraulic testing under test pressure:
1 drop per minute
Alternating valves:

up to PN 160 WV
– leakage rate hydraulic testing under test pressure:
20 drops per minute
Shut-off valves:
– for high pressure ratings
up to PN 630 bar VDHA
Design:
1. For materials, permissible working pressures, temper-
atures, ow medium torques for male studs etc. see
relevant pages of the catalogue.
2. Tube connection ends must be assembled according
to the Parker EO/EO-2 assembly instructions.
3. The valve bodies must be held rigidly during assembly
of the tube connection ends.
4. Test pressures for non return valves:
PN in conformance with O.D. information see chapter C.
5. Pressure drop values please see p. C12 and diagrams.
Caution!
Please note the admissible pressure ratings for the EO-
tube ends.

The pressure specication PN for hand-operated shut-off
valves and quarter turn ball valves applies to the design
factor 1,5 (according DIN 3230 T5 and ISO 5208).

Notes:
To assess the suitability of valves for specic applications, please advise us of the exact specication of the medium
to be used, max. working pressure incl. pressure peaks, temperature and frequency of valve operations. If water is
used, indicate type of water or additives, if any.

RHD/V/Z non return valve
Characteristics:
Poppet check valve with a 90° valve seat with an elasto-
mere sealing disc. Poppet stop for controlled valve open-
ing. Damped opening action to minimize shock and noise.
No reduction of cross section. Maximum ow velocity not
more than 8 m/sec. Sealing of male stud thread by Eolas-
tic soft seal with types RHV and RHZ.
Opening pressure:
Standard 1 bar (on request also 0.2, 0.5, 2, 3, 4, 5 and
6 bar are avail able; please specify on order). For working
pressure see appropriate tables. Cracking pressure toler-
ance: ± 20 %.
Material:
•Steel zinc-plated (CF Cr[VI]-free), seals in NBR
(e.g. Perbunan), or (FKM) on request.
Perbunan = registered trademark of Bayer
•Stain less steel valves have FKM as standard.
(Up to 3 bar cracking pressure)
•Brass-valves (CuZn35Ni2 2.0540) with internals (1.4571)
available on request.
(Up to 3 bar cracking pressure)
Assembly:
See assembly instructions for EO/EO 2 connections.
Non-return valves are all packaged against contam ination.
Media:
Hydraulic oil, low ammability hydraulic uids (excent
for types HFC: for HFD types; FKM seals are necessary).
Air pressure tested (please indicate on order). Not suitable
for steam, combustible/explosive gases, or oxygen.
For water applications, please consult Parker with details
of water and any additives.
