Key Features & Benefits


Double-seat & Sleeve-guided Balanced Trim

Feature: Split or integral standard cage design with balanced trim structure

Benefit: Eliminates excessive pressure impact on the valve core, ensures precise flow control, reduces wear and tear, and extends the valve’s service life by 30% compared to single-seat alternatives.


Multi-type Bonnet & Seal Options

Feature: Normal temperature, high-temperature heat dissipation, and extension-type bonnets; optional bellows seal

Benefit: Adapts to extreme temperature environments from -100℃ to 560℃, prevents medium leakage effectively, and reduces maintenance frequency for high-risk applications.


Diverse Actuator Compatibility

Feature: Works with pneumatic membrane, pneumatic piston, electric, and electro-hydraulic actuators

Benefit: Flexibly matches different industrial control systems, supports both manual and automatic adjustment, and meets the control needs of various complex working conditions.


Compliant with International Standards

Feature: Adheres to ASME, GB, HG, and IEC standards for connections and leakage performance

Benefit: Ensures seamless integration into global industrial projects, eliminates compatibility issues, and simplifies procurement and installation processes.
