Holmbury / TGW Series
Coupling Type: Hydraulic Couplings & Adapters
High Pressure Poppet type Screw Couplings
Holmbury High Pressure Poppet Type Screwed Couplings are designed to withstand high pressures and pressure pulses.
High pressure pulses create forces that act to separate the male and female couplings.
With couplings that use ball-in-groove retaining mechanisms, the separating forces are concentrated onto a relatively small area - point contact of the balls - which can cause Brinelling (indentation of the balls into the groove).
Brinelling will lead to leakage and eventually seizure of the coupling.
Screwed couplings have a screw thread retaining mechanism that distributes the separating forces over a large surface area, thus eliminating brinelling.
- Screw thread retaining mechanism to eliminate brinelling
- Connection and disconnection can be performed even with a low residual hydraulic pressure in the line
Mobile plant, agricultural implements and general industrial equipment.
Zinc plated carbon steel body material with nitrile seals and PTFE backing ring.
Holmbury High Pressure Poppet Type Screwed Couplings are available in stainless steel.
Please contact the Holmbury Sales Dept to discuss the application.
Working temperature range with nitrile seals is -20°C to +100°C Couplings are also available with Viton seals for an operating temperature range of -15°C to +180°C.
