Muti-Port Fusion Ventil

DESIGN FEATURES Raised, conical seat prevents solids build-up from interfering with seal. Seat is hardfaced with Stellite to meet severe service. Alternative space age alloys are also used. LAMINATED RESILIENT DISC SEAL to 1000oF (538oC) One to four graphite layers are carefully assembled between stainless steel rings using Phenolic Resin. Flexible seal rings without glue are available for higher temperatures "ZERO LEAKAGE" - SEAT TIGHTNESS The disc seal, evenly compressed around its circumference, produces a wedging effect which flexes the seal ring and reacts like a spring. The resilient seal assures "zero leakage" of liquids or gases to API 598 - resilient seat standard. Resiliency in the seal allows disc movement during thermal cycles while retaining tight shutoff as shown. SIZEAND PRESSURE Size Range:2” 80” Pressure Rating:125lb 600lb
