Holmbury / H Series
Description:
Flat Face Couplings H Series
Coupling Category
Flat Face Couplings
Manufacturer
Holmbury
Construction plant, mobile equipment, general industrial, nuclear, mining and
agricultural. Applications involving dusty or dirty environments and where oil
loss on disconnection cannot be tolerated.
ADVANTAGES
STANDARDS
Conforms to ISO 16028 (2006) in all respects, i.e. dimensions and performance.
MATERIALS
Hardened carbon steel body, zinc plated, nitrile seals.
CONNECTION / DISCONNECTION UNDER PRESSURE
Connection with residual pressure in the line will be difficult or impossible.
For applications where connection under pressure is required, a Holmbury APM male coupling, or a screw coupling from either the HSC, VP or VEP ranges is recommended.
Disconnection of any quick disconnect / quick release coupling whilst under full system pressure can be very dangerous and should not be attempted.
ADVANTAGES
- Flat mating faces are easily wiped clean to prevent the ingress of contaminants.
- Improved flow path minimises the pressure drop.
- Non-spill design avoids fluid loss during connection and disconnection.
- No air intrusion during connection.
- Locking sleeve prevents accidental disconnection.
