Quick-Connect DN4.8 Socket with Valve, Threaded, Chrome-Nickel Brass, Series 1100N

The universal quick-connect socket with double shut-off is a reliable solution for demanding liquid applications, ensuring maximum safety by preventing leaks during disconnection. Available with external or internal BSP thread, it is engineered for use with water, steam, oils, and fuels, combining compact dimensions with excellent flow performance. Its robust construction, featuring a chrome-nickel brass body and stainless-steel balls and springs, guarantees long-lasting durability even under intensive use. Designed for two-handed operation, the coupling delivers a flow rate of 9.5 l/min for water (Δp = 1 bar, Kv = 0.57) and up to 430 l/min for air (Pe = 6 bar, Δp = 0.5 bar), with a maximum working pressure of 20 bar (10 bar for steam). The socket adapts to various operating conditions thanks to multiple sealing options: NBR for standard use (-20°C to +100°C), Viton for high-temperature resistance (-25°C to +200°C), and EPDM for extreme cold or heat (-50°C to +150°C). Compact, easy to handle, and exceptionally reliable, this coupling is the ideal choice for industries seeking efficiency, safety, and versatility in fluid transfer systems.
