PUSH & PULL QRC AS PER ISO A TYPE
1⁄4" - 2" POPPET VALVE TYPES TO ISO 7241 SERIES A
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 :
- Smaller.
- Easier to connect and release.
- 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.
Trivalent plated, heat treated carbon steel. Nitrile 'O' ring seals are fitted as standard. VITON seals are available on request.
