The 3-Piece Threaded Steel Ball Valve, designed to DIN standards and rated for PN 25, is engineered for superior performance in demanding industrial applications. Its robust construction ensures reliable shut-off and control of fluids, gases, and steam in high-pressure environments up to 25 bar. The three-piece design allows for easy maintenance and inspection without removing the valve from the pipeline, reducing downtime and operational costs.This valve features a threaded connection for secure installation and compatibility with various piping systems. Made from high-grade steel, it offers excellent resistance to corrosion, wear, and high temperatures, making it ideal for use in chemical processing, oil and gas, water treatment, and manufacturing industries. The full-port design minimizes pressure drop and allows for efficient flow, enhancing system performance.Key specifications and benefits include:Material: Carbon or stainless steel options for durabilityPressure Rating: PN 25 (25 bar)Temperature Range: -20°C to 180°C, suitable for diverse conditionsThread Type: BSP or NPT threads for global compatibilitySeat Material: PTFE or reinforced PTFE for tight sealing and chemical resistanceFire-safe design available for enhanced safety in critical applicationsIdeal for both on/off and throttling services, this valve ensures long service life and minimal leakage, backed by compliance with international standards. Its ergonomic handle allows for easy operation, and it can be automated with actuators for remote control, providing flexibility in industrial automation systems.
