Description
RK Triple offset valves outperform traditional valves with increased durability, reliability and lower ownership cost. The seat of the triple offset valve is designed to minimize wear, provide lower maintenance cost and extend service life. The ‘zero leakage’ sealing capabilities of triple offset valves provides the performance to keep your processes operating reliably at top efficiency even in extreme operating conditions. All of these benefits also come with a large weight saving when compared to many other valves, making for much easier installation and maintenance.
