Globe Control valve
PCV Globe Valves—available in both top-guided and cage-guided designs—offer exceptional versatility for general-purpose flow control across petrochemical and refinery applications. Built with a modular structure, they meet international standards such as ANSI, API, ASME, ISO, DIN, and JIS.
Each valve features a straight-body design with three flanged ends and a single-seat configuration. The cage-guided balanced plug ensures enhanced performance, especially in high-pressure and high-temperature service. A wide range of sizes, pressure classes, and material grades are available to match the specific requirements of various process fluids.
Flow control is precisely managed via a CNC-drilled cage, which acts as a full-length guide for the plug during its travel. This ensures stable, accurate, and responsive regulation under all operating conditions.
Engineered for durability and efficiency, PCV Globe Valves provide precise modulation across a wide flow range. The plug design is optimized to offer excellent rangeability, reduced minimum controllable flow, and minimized erosion, making them a reliable choice for critical flow control needs.
Specialized Trims for Demanding Applications
PCV Globe Valves can be equipped with replaceable specialized trims tailored for high-performance service conditions, providing flexibility for adaptation to high-temperature and critical process environments.
Available trim options include:
Standard Trim – For general-purpose flow control
Low Noise Trim – Designed to minimize aerodynamic noise in high-pressure gas service
Double Case Trim – Engineered for enhanced pressure recovery and protection against cavitation in severe liquid service
These configurations are ideal for high differential pressure applications, including gaseous fluids and cavitating liquid services, where precise control and operational stability are essential.
