LIVE-LOAD - 1

– Belleville Springs – Gland Follower – End Rings – Sealing Rings – Spacer Bushing – Shaft/Stem VALVE STEM PACKING Technical Specification Minimal Gland Adjustments Required Design Features • Reduce maintenance cost • Trained technical support: sales/service engineers provide training programs, on-site surveys, and supervise installations. • Control emissions • Self adjusting • Design and application engineering support • Equalized loading • Reduced number of rings required for deep stuffing boxes • Ideal for valves in remote or hard to reach locations • Computerized live-load program: calculates proper load data for disc spring selection, configuration, and gland nut torque. • Optimum packing materials: utilizes die-formed Crane-foilTM packing rings for longer sealing life, resulting in less corrosion in the box and less leakage in the valve. Highest quality braided graphite or carbon fibers serve as wiper rings and anti-extrusion rings. High compressive strength graphite spacer. • Belleville springs: maintain packing compression above the minimum sealing pressure as packing relaxes and wears. • Nuclear certifiable materials: materials can be certified to meet demanding nuclear service purity levels of low chloride, fluoride, halogens, sulfur and embrittled metals. Industries Served • Chemical processing • Power generation • Fossil fuel • General industry • Nuclear power • Oil and refinery • Petrochemical
