VP-P
The “VP-P” screw flat face coupling series is the technological solution to demanding hydraulic applications. The screw connection system eliminates premature wear and the “brinelling” caused by a mechanical locking ball system. This makes the “VP-P” series suitable for high operating and impulse pressures. The triple valve system allows connection of the coupling safely even in presence of high internal residual pressure and at the same time avoiding fluid loss. The safety sleeve integrated in the connection system prevents accidental disconnection making the “VP-P” series ideal for the most extreme operating conditions where strong vibration and torsion issues are present.
BENEFITS
- *Connection under residual pressure is allowed in both sides, the internal valve system allows an easy connection and the disconnection is included.
- Flat face is easy to clean, reducing the inclusion of contamination to the hydraulic circuit.
- Minimal fluid loss during disconnection, reducing fluid loss to the environment.
- Minimal air inclusion during connection / disconnection.
- Patented internal valve design creates minimal pressure drop, maintaining circuit efficiency in the system.
- Internal pressure release valve system allows an easy connection with high internal residual pressure.
- The safety sleeve integrated in the connection system prevents the accidental disconnection.
- The modular design allows flexibility with a wide range of configurations.
- High resistance at impulse pressures.
- Safe and simple to use.
- BOP – Specific dimensions of Stucchi VEP-P, VP-P and VOF series are fire tested and Lloyd certified in accordance with API 16D and the EUB Directive #36. For complete technical information please contact Stucchi technical support.
