Is the Brass DN5 Quick-Connect Socket with Valve, Threaded – Series 21KA suitable for both air and water applications at the specified flow rates and pressures?

Yes. The Brass DN5 Quick-Connect Socket with Valve, Threaded – Series 21KA is suitable for both air and water applications at the specified flow rates and pressures. It delivers 560 l/min for air at 6 bar with only a 0.5 bar pressure drop and 8 l/min for water at a 1 bar pressure drop (Kv=0.48). Its maximum working pressure of 35 bar, robust brass construction with stainless steel internals, NBR sealing, and operating temperature range of -20°C to +100°C make it appropriate and reliable for industrial air and water use within those specified conditions.

Can the Brass DN5 Quick-Connect Socket with Valve, Threaded – Series 21KA withstand continuous operation at 35 bar and the stated temperature range (-20°C to +100°C) without performance degradation?

Yes. The Brass DN5 Quick-Connect Socket with Valve, Threaded – Series 21KA is specified and engineered to operate continuously at up to 35 bar and across the stated temperature range of -20°C to +100°C without performance degradation. Key points supporting this: - Rated working pressure: specified up to 35 bar. - Materials: robust brass body with stainless-steel springs and balls for wear resistance and durability under pressure. - Sealing: high-quality NBR seals compatible with the stated temperature range ensure maintained tightness. - Performance data: proven flow efficiency (560 l/min air @ 6 bar with 0.5 bar drop; 8 l/min water @ 1 bar drop, Kv=0.48) indicates reliable operation under load. - Design intent: marketed as a professional-grade coupling for demanding, intensive use and continuous operation. Notes/limits: Continuous use at the extremes of pressure/temperature assumes appropriate installation, compatible media, avoidance of mechanical shock or corrosive environments beyond materials’ limits, and adherence to maintenance schedules. If your application includes aggressive chemicals, temperatures continuously near limits, or cyclic pressure spikes above 35 bar, consult the manufacturer for qualification or testing under those specific conditions.
