Cấu Tạo Bên Trong Tạo Nên Sự Khác Biệt
Engineered for Industrial Flow Control
The STRAVEX Rotary Globe Control Valve is designed for process applications where control stability, leakage performance, and actuator efficiency matter.
Its eccentric plug design helps minimise wear during throttling while generating additional seating force at closure. This supports low leakage, reliable shut-off, and reduced actuator requirements in demanding industrial environments.
Suitable for chemical, metallurgical, power generation, and general industrial process control applications, this valve provides a practical solution for systems that require both precise modulation and long-term operational reliability.
Key Advantages at a Glance
- Compact and lightweight flangeless design, available up to ANSI Class 600.
- Suitable for mounting with JIS, EN, and ANSI flanges.
- Manual override comes as standard for easier site operation.
- High Cv/Kv performance, supported by the Rotary Globe design.
- Three different Cv options are available for every valve size.
- Can be changed from Normally open to Normally closed on site using standard tools.
- More cost-effective than standard linear Globe Control valves due to reduced material usage.
- Positioner mounting follows the ISO 5211 standard.
01. Integrated Body and Bonnet Construction
The one-piece cast body with integral bonnet reduces static pressure boundary joints. With only one dynamic sealing point at the shaft, the design helps minimise potential leakage paths and improve long-term reliability.
02. Eccentric Plug Geometry
The eccentric plug structure supports stable engagement between the plug and seat during operation. This helps reduce instability during throttling and improves seating performance when the valve closes.
03. High Flow Capacity
An optimised internal flow path provides high flow capacity and wide rangeability, making the valve suitable for heavy-duty industrial process control.
04. Optional Pressure Reduction Design
For applications involving higher pressure drop, a multi-hole plate can be installed inside the valve body to improve flow stability and help mitigate flashing or cavitation risks.
05. Flexible Multi-Hole Plate Options
Multi-hole plates are available in integrated internal or combined external configurations, allowing the valve to be adapted to different process requirements.
06. Options for Crystallising and Erosive Media
Heat jacket construction and erosion-resistant surface treatment are available for services involving crystallisation or abrasive fluids.
07. Simplified Maintenance
The symmetrical rotary plug design allows easier replacement of internal components and actuators without special orientation requirements.
08. Tight Shut-Off Options
Metal seat construction supports ANSI Class IV or Class V shut-off, while soft seat construction supports ANSI Class VI shut-off performance.
