Angle Type Cage-Guided China Control Valve

Precision Flow Control for Severe Service Applications

Introduction

In industries where process conditions are extreme—featuring high pressures, elevated temperatures, and large pressure differentials—valve reliability and performance are critical. The Angle Type Cage-Guided Control Valve is specifically engineered for such demanding applications, delivering unmatched durability, precision control, and long service life.

This high-performance valve is ideal for handling clean liquids and gases in sectors such as power generation, petrochemical refining, oil and gas production, and chemical processing. Whether regulating high-pressure steam, managing flashing fluids, or controlling boiler blowdown, this valve ensures superior flow modulation, minimal noise, and reduced maintenance requirements.

Engineered Design for Harsh Environments

Cage-Guided Plug Mechanism

The core of this valve’s reliability lies in its cage-guided design, which provides excellent plug stability. Unlike stem-guided valves, cage-guided configurations reduce vibration and plug misalignment, ensuring a longer service life and more consistent performance, even under severe flow turbulence.

Enhanced plug alignment for stable, precise flow control

Noise and vibration mitigation via drilled-hole cage configurations

Maintains reliable flow characteristics across a wide range of conditions

Versatile Trim Options for Precise Control

To meet a broad spectrum of application needs, the valve offers multiple interchangeable trim types:

Single P-Port Trim – Standard for balanced, general-purpose flow regulation

Multi-Step Pressure-Reducing Trim – Mitigates cavitation and vibration in high ΔP systems

V-Notch Cage Trim – Provides fine resolution for sensitive or low-flow control tasks

Flashing Service Trim – Designed with erosion-resistant geometry for flashing fluids

Advanced Performance Features

Anti-Cavitation and Anti-Flashing Capabilities

Multi-stage pressure reduction is built into the valve trims to prevent cavitation and flashing, two common issues in high-energy flow systems. Hard-faced internal materials extend wear life, while specially designed cages and ports minimize internal turbulence and vibration.

Hard alloys resist internal erosion from flashing and turbulent flows

Low-noise operation even under extreme conditions

Reliable control of vaporizing liquids and saturated steam

Flow Direction Flexibility

Flow orientation can be customized to meet process demands:

Flow-to-Close (FTC) for liquid media where positive shutoff is required

Flow-to-Open (FTO) for steam or gas services where fast response is critical

Key Design Features

Multi-Spring Pneumatic Actuator – Delivers precise, repeatable, and responsive control with low hysteresis

Fail-Safe Options – Choose from Fail-Open, Fail-Closed, or Fail-In-Place configurations for safety assurance

Top-Entry Body Design – Enables internal maintenance without removing the valve from the pipeline

ANSI Class IV, V, or VI Shutoff – Ensures proper sealing based on application demands

Modular Trim Sets – Allows quick trim changes based on flow characteristics
