Holmbury HDB 3/4 in. Zinc Nickel Decompression Block Coupling, ISO 16028 W/ NBR and PTFE Seals

Description

Holmbury's HDB Series is a block coupling designed for the quick changeover of hydraulic attachments for skid steer loaders, compact loaders, backhoe loaders and compact utility vehicles. The decompression feature enables the operator to alleviate trapped pressure, allowing the quick and easy connection of various attachments.

Features

• Decompression achieved by simple pull feature which also prevents accidental system discharge
• All couplings are flflat face and are designed to the ISO 16028 Standard
• Low profifile coupling design minimises side loading
• Coupling arrangement can be ordered in 1/2” (Size 12) for standard flflow or 3/4” (Size 19) for high flflow applications
• Case drain coupling is standard 3/8” (Size 10)
• Operating temperatures (With NBR seals): -40°C (-40°F) to 106°C (223°F)
• Maximum working pressure 350 bar
• Decompression force 130 Nm at 275 bar trapped pressure
