Screw-to-Connect Couplings · HS Series

Screw-type couplings of the HS series are coupled by simply screwing the carrier and probe halves together until the thread contacts the limit stop. The coupling is designed to open both valves “en bloc“ in this position. For this reason, and due to their rugged design, they are particularly well suited for heavy-duty service conditions in construction machinery. The range of operating pressures of this series is higher than that of the VOSWINKEL HP series.

Screw-type couplings of the HS series can be coupled on both sides under pressure of up to 50 / 725 PSI bar. The self-locking connection thread prevents any disengagement of the screw connection caused by vibrations. The screw sleeve of the probe, when correctly locked, must cover the black brake ring of the carrier.
