Velan, Inc. High-pressure Forged Metal-seated Ball Valves Type R

Description
Severe service metal-seated ball valves for high temperature, abrasive and corrosive applications. Features and benefits • Bi-directional sealing with preferred direction. • Advanced HVOF or Plasma spray custom trim coating technology with hardness in excess of 70 RC. • Superior ball/seat finish to 2 - 4 RMS. • Unique ball/seat spring-loading technology to assure tight shutoff at low differential pressures and / or when fines are present. • Complete ball/seat set individually vacuum tested to verify sealing integrity. • Robust blowout-proof stem. • Low emission stem seal with advanced live-loaded packing arrangement. • Stem bearing reduces side thrust effect on packing and prevents stem wobbling. • CoCr alloy thrust washers absorb stem loading moments and reduce valve operational torque. • Allowable leakage at full δP: MSS-SP-61. Tighter shutoff available upon request. • All valves are inherently fire safe. • Designed to ASME B16.34. • Flow relief is incorporated into both the upstream and downstream ball lips increasing the area exposed to flow and thus reducing erosion due to velocity upon initial valve opening. • Downstream and upstream body-seat lapped contact.
