Hydraulic quick coupling with valve and pressure eliminator, socket with GW BSP, in zinc-nickel coated steel, HOLMBURY

Q: Does the Hydraulic quick coupling with valve and pressure eliminator, socket with GW BSP, in zinc-nickel coated steel, HOLMBURY prevent accidental disconnection under high residual pressure?

Yes. The Hydraulic quick coupling with valve and pressure eliminator, socket with GW BSP, in zinc-nickel coated steel, HOLMBURY is designed to prevent accidental disconnection under high residual pressure. It features a built-in pressure eliminator that facilitates safe connection when high residual pressure exists, plus a shut-off valve that isolates the circuit. Additionally, the socket includes a locking ring that prevents unintended disconnection and an extra O-ring for improved sealing. The coupling is built for heavy-duty use (steel with zinc-nickel coating, up to 350 bar depending on size) and incorporates safety features (4:1 safety factor, NBR seals) specifically to address safe coupling/disconnection under pressure.

Additional information

Material	CS – steel (cast iron)

Holmbury quick coupling socket (Nordic interchange) with shut-off valve and internal BSP thread features a built-in pressure eliminator, facilitating connection when there is high residual pressure in the system. The quick couplings are designed for heavy-duty working conditions. The sockets have an additional O-ring, making them ideal for gas installations, and a ring that prevents accidental disconnection. Applications: general industrial, hydraulic power (hydraulic oil). Material: steel with zinc-nickel coating. Working pressure: up to 350 bar (depending on diameter). Safety factor 4:1. Sealing: NBR rubber. Operating temperature: from -25°C to +100°C. Flow is specified for a pressure drop of 3 bar.
