Stucchi Ball Quick Couplings IR Series and IV-HP Series

The Stucchi Ball Quick Couplings are available in IR and IV-HP series, with ball or screw locking systems. Made of carbon steel, they withstand pressures up to 700 bar and temperatures from -20 °C to +100 °C. Compatible with BSP and NPT threads, they include versions with NBR and PTFE seals. Ideal for hydraulic high-pressure use and complex industrial applications.

BALL VALVES

Description

The Stucchi Ball Quick Couplings include two distinct series: IR Series, interchangeable ISO 7241-1 “A” in 1/2” size, and IV-HP Series, designed for high-pressure applications.


IR Series – ISO 7241-1 “A” Interchangeable (only 1/2” size)

The IR Series quick couplings feature a ball locking and shut-off system with single-action sleeve. Coupling and uncoupling are not allowed under pressure. The hardened steel ball valves improve wear resistance. The overall dimensions are compact.

Main applications:

  • Oil&Gas

  • Earthmoving

  • Vehicles

  • Industry

  • Hydraulic equipment

  • Agriculture

  • Refrigeration

  • High pressure

  • Chemical and food industry

  • Cooling

Technical features:

  • Locking system: single-action sleeve.

  • Shut-off system: ball type.

  • Material: high strength carbon steel.

  • Available threads: BSP, NPT.

  • Seals: NBR nitrile.

  • Working temperature: from -20 °C to +100 °C.

  • Available sizes: 1/4″, 3/8″, 1/2″, 3/4″, 1″.

  • Max flow: up to 150 l/min.

  • Working pressure: up to 300 bar.

  • Spillage: from 0.13 ml (1/4″) to 6.00 ml (1″).

TIC Version (only for 1/2″): mushroom-type coupling with shielded valve that reduces “flow checking” effect when used with a connection under pressure.


IV-HP Series – High Pressure Couplings

The IV-HP Series couplings have a screw-type locking and shut-off system. Coupling/uncoupling is not allowed under pressure. They are designed for high-pressure applications.

Main applications:

  • Oil&Gas

  • Earthmoving

  • Vehicles

  • Industry

  • Hydraulic equipment

  • Agriculture

  • Refrigeration

  • High pressure

  • Cooling

  • Chemical and food industry

Technical features:

  • Locking system: screw type.

  • Shut-off system: screw type.

  • Material: high strength carbon steel.

  • Available threads: NPT.

  • Seals: NBR nitrile; in 3/8” size there is a PTFE back-up ring.

  • Working temperature: from -20 °C to +100 °C.

  • Available sizes: 1/4″, 3/8″.

  • Max flow: 12 l/min (1/4″), 23 l/min (3/8″).

  • Working pressure: 700 bar (10,000 psi).


Accessories and Spare Parts

Protection caps (IR and IV-HP Series):

  • Red PVC with cord (IR).

  • Black plastic or galvanized steel with cord (IV-HP).

Female seal kits:

  • IR: NBR seals, separate code for each size.

  • IV-HP: NBR seals (1/4”) and NBR + PTFE (3/8”).
