DESIGN ADVANTAGES: PATENTED ISO 5211 DIRECT MOUNT PAD Allows direct mounting of pneumatic and electric actuators, no brackets and couplings needed, easy and low cost for automated service. EXTRA HIGH CYCLE LIFE Maintenance free live loaded double sealing high cycle stem packing system provides extra longer service life. COMPACT SPACE SAVING DESIGN, AS AN ALTERNATIVE OF SPLIT BODY BALL VALVES BLOW OUT PROOF STEM ANTI-STATIC DEVICE AS STANDARD FIRE SAFE DESIGN COMPLY WITH BS6755 AND API 607 WIDE RANGE OF SEAT AND SEAL MATERIAL AVAILABLE INVESTMENT CAST BODY CONSTRUCTION 1. PYRAMIDAL STEM WITH STEM SEAL First stage of defense against leakage. The 45 degree slope of the stem accompany by the stem seal effectively blocks all leak path from forming during rotation. 2. V-RING STEM PACKING Second stage of defense against leakage. Triple layers of V-Ring Chevron packing expands side ways as it is being compressed, blocking all air pockets thus preventing leak path. The grinding effect of metal to PTFE contact. 3. GLAND Made of stainless steel, equally distributes the compressive force on the packing and the seal. 4. BELLEVILLE WASHER Release stored compressive energy for automatic compensation of seals due to wear and tear fluctuation of temperature and pressure. 5. LOCK SADDLE Stabilizes the stem nut to keep it from loosening. 6. STEM NUT Compress the entire stem system to enable blocking of leakage. 7. ANTI-STATIC DEVICE Standard applied between stem and ball, stem and body.
