Securaseal® TX-Series Acid Injection Ball Valve

Features & Benefits

Designed for the most extreme process and environmental conditions, Velan’s Securaseal acid injection top-entry metal-seated ball valve provides customized application-focused features that deliver a robust valve for highly corrosive slurry–one of the most critical applications in HPAL (high pressure acid leaching). 

• Top-entry, fully forged, thicker-wall valve for greater strength, lowest operating piping stresses, and extra corrosion allowances.
• U.S. patent pending features designed specifically for highly corrosive slurry in HPAL.
• VEL-Ta, Tantalum proprietary coating is applied to all ‘wetted’ surfaces ensuring the highest corrosion protection in service.
• Robust blowout-proof fully guided stem, has the largest Maximum Allowable Stem Torque (MAST) of all severe service ball valves, ensuring normal operation regardless of valve orientation and process conditions. 
• Ball and seats are 100% fully mate-lapped and coated with the latest coating solutions that fit the requirements of the service conditions.
• Velan stem packing technology guarantees a low emission stem seal in compliance with the highest industry standards.
• Unique precision machined slurry-proof upstream floating seat.
• Zero seat leakage test criteria
• Bidirectional sealing design
• Heat dissipating features to lower temperature on valve parts.
• Visual detection surface treatment to identify exterior leaks.
• Lifting points that allow easy horizontal and vertical installation.
• High visibility position markers.
• ISO and MSS standard actuator mounting patterns.
• Velan’s highly efficient Cable Drive actuators offer the highest safety margin with consistent linear output torques.
