This professional one-piece ball shut-off valve, manufactured in Europe, is engineered for demanding industrial applications and ensures reliable performance across a wide range of media, including air, neutral gases, water, chemicals, and petrochemical products free of solid impurities. Its robust body is made of nickel-plated brass casting, complemented by a chrome-plated brass ball, PTFE ball sealing, and NBR stem sealing, guaranteeing durability and resistance to wear. The valve features a straight polyamide lever with an interchangeable label system, available in standard red as well as yellow, blue, green, or white, enabling clear installation marking and enhanced safety. Designed with stem blow-out protection, it complies with PED 2014/68/EU (Article 4, paragraph 3), RoHS 2011/65/EU, and REACH 1907/2006, and is entirely silicone-free. The valve operates within a temperature range of -20°C to +80°C, with optional versions offering extended ranges up to +130°C using Viton, EPDM, or HNBR stem sealing materials. Its versatility is further underlined by the ability to work under vacuum conditions down to -0.99 bar, while BSP and BSPT threaded connections (ISO 228-1 / ISO 7-1) ensure universal compatibility. With optimized flow performance defined by Kv and Q values, this valve combines precision engineering, safety, and adaptability, making it an excellent choice for modern industrial systems seeking efficiency, reliability, and compliance with the highest European standards.
