The needle valve with a non-rotating PEEK stem tip is engineered for direct installation from the external thread side in HSSC sampling cylinders, ensuring maximum reliability and ease of use. Equipped with a replaceable safety insert, the system provides advanced protection against excessive pressure by utilizing a welded rupture plate that activates at a defined threshold, safely releasing the medium through precision-designed openings in the hexagonal head. Manufactured from high-grade AISI 316 stainless steel with an aluminum knob, the valve guarantees durability even under demanding conditions, while premium sealing elements – NBR o-ring, PTFE ring, and viton o-ring – deliver exceptional tightness and long-lasting performance. The design allows quick replacement of the safety insert in the field without removing the valve, minimizing downtime and maintenance costs. Tested at 120% of working pressure in compliance with ISO 14246 and fully certified under the TPED directive (2010/35/EU), the valve ensures uncompromising safety and regulatory conformity. With a working pressure of up to 206 bar at 37°C, burst pressure options of 131 or 196 bar, and an operating temperature range from -20°C to +122°C, it offers outstanding versatility across a wide spectrum of applications. The optimized flow coefficient of 0.53 Cv further enhances efficiency, making this valve the ideal solution for industries requiring precision, safety, and reliability in high-pressure sampling processes.
