การออกแบบและประสิทธิภาพ
• Wide Range of Seat Seal Options
Offers flexibility with seals in EPDM, PTFE, or metal-to-metal configurations to suit different application needs.
• Pressure-Balanced Design
Allows the use of low-power actuators, enhancing energy efficiency and system adaptability.
• Optimized Valve Plunger Design
• Separate sealing and regulating surfaces minimize wear, extending service life.
• Dual stem guides ensure precise plunger positioning and reduce the impact of high pressures during operation.
• Advanced Packing System
Self-sealing chevron packing with spring-loading ensures tight sealing and long-lasting performance.
• Enhanced Stem Durability
Features hardened, polished, and lubricated stem surfaces to reduce friction and increase the lifespan of the packing assembly.
• Service-Friendly Construction
Modular design enables easy maintenance and allows for changes to valve flow characteristics during servicing.
