Manufacturer
Holmbury
Hand held and excavator mounted breakers, shears and all systems subject to high pressure pulses. Any system where connection or disconnection under pressure is required.
SPECIFICATION
Operating temperature range: -20°C to +100°C Fluid loss during disconnection: zero to 0.02ml Materials: QPQ hardened carbon steel body, other external parts zinc plated. PTFE and nitrile seals.
INTRODUCTION
Holmbury VP Series Screwed Couplings are ideal for systems subjected to high
pressure pulses since they are immune to Brinelling. They provide the extra
security of a screw connection with locking sleeve.
ADVANTAGES
- Connect and disconnect under pressure
- Screw thread connection eliminates Brinelling
- Flat faces easily wiped clean to prevent ingress of contaminants
- Non-spill design avoids fluid loss during connection and disconnection
- Locking sleeve indicates that connection is complete and prevents accidental disconnection
- Bi-directional flow with low pressure drop
