to ISO 7241 Series A
Holmbury IA Series, ISO.A couplings are the ideal
choice where a tough, durable product of superior
quality is required. They are perfectly suited to industrial
and agricultural applications. A poppet valve is used to
minimise the pressure drop characteristics and provide
a positive sealing arrangement.
In comparison to ISO.B couplings, ISO.A are:
2. Easier to connect and release.
Zinc plated, heat treated carbon steel. Nitrile 'O' ring
seals are fitted as standard. VITON seals are available
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
Poppet valves have balanced springs and calibrated
oil flow passages to minimise the pressure drop.
Poppet valve seals have shockproof protective
