Holmbury
ISO.B SERIES - PULL BREAK HYDRAULIC COUPLINGS
⅛" - 1" Poppet Valve Types to ISO 7241 Series B
ISO.B carbon steel couplings
ISO.B S/S stainless steel couplings
INTRODUCTION
Holmbury ISO.B Series couplings are designed to be tough, durable and of superior quality to competing ISO 7241 products.
They are ideally suited to heavy industrial applications which would typically include:
FEATURES
Positive, quick connection ensured by the snap together locking ball system. When connected the male and female halves can rotate, even under pressure, thus avoiding any torsional stress in the flexible hoses. Designed to withstand high pressure peaks and pulses. Poppet valves have balanced springs and calibrated oil flow passages to minimize the pressure drop. Poppet valve seals have shockproof protective edges.
CONSTRUCTION
ISO.B couplings - Heat treated, carbon steel, zinc plated . Nitrile ‘O’ ring seals with PTFE backing rings.
ISO.B S/S couplings - AISI 316 stainless steel. Nitrile ‘O’ ring seals with PTFE backing rings.
OPTIONS - alternative seal materials available on request:
Ethylene-Propylene
Viton
Neoprene
ISO.B TESTS
Life - 1,000,000 cycles from 0 - 250 bar at a frequency of 1Hz.
