Description:

FL Series / Stainless Steel Flat Face Couplings

Coupling Category

Flat Face Couplings

Manufacturer

Holmbury

Holmbury FL Series Stainless Steel Couplings have a high resistance to corrosion and are suitable for use with many fluids which include: acids, gas, and demineralized water. They are the ideal choice for many industries such as marine, food, gas, chemical and pharmaceutical.

INTRODUCTION
FL Series couplings have been designed for applications involving the transmission of corrosive fluids and/or operation in corrosive environments. One of the most important benefits of these couplings is no fluid spillage on disconnection. Holmbury flat face couplings have been produced since 1984. Over the years, extensive experience has been gained in the design, manufacture and application of these products. Consequently, Holmbury couplings have won design innovation awards and are widely regarded as the World's leading brand of flat face coupling.

ADVANTAGES
  • Flat faces can easily be wiped clean before connection to prevent the ingress of contaminants into the circuit.
  • Clean disconnection - non-spill design.
  • No air intrusion during connection.
  • Streamlined flow path minimizes pressure drop.
  • Locking sleeve prevents accidental disconnection.
  • Bi-directional flow
MATERIALS
Body and structural components - AISI 316* Spring guide in male coupling - brass Springs - AISI 302 Locking balls - AISI 316 Seals - Viton and PTFE as standard.
