ISO.A SERIES PULL BREAK HYDRAULIC COUPLINGS Va" - 2" Poppet Valve Types to ISO 7241 Sries A | |||||||||||
INTRODUCTION Holmbury ISO.A Sries 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. COMPARISONS In comparison to ISO.B couplings the ISO.A Series are: 1. Smaller. 2. Easier to connect and release. 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 minimise the pressure drop. ★ Poppet valve seals have shockproof protective edges. MATERIALS Zinc plated, heat treated carbon steel. Nitrile 'O' ring seals are fitted as standard. VITON seals are available on request. | |||||||||||
