Description
Control Gate Valves (actuated regulating gate valves) are high-performance pipeline valves engineered for both precise flow modulation and reliable bubble-tight shut-off. Equipped with smart electric or pneumatic actuators, these valves respond to continuous 4-20mA signals from control systems, making them ideal for heavy-duty industrial automation in water treatment, oil & gas, and chemical processing.
Designed for severe operating conditions, these valves complement our industrial butterfly valves and interface smoothly into automated piping with precision-machined industrial flanges.

Key Features & Actuation Capabilities
Unlike basic manual gate valves, modulating control gate valves deliver precise fluid positioning and remote automation:
- Precise Flow Modulation: Configured with specialized trim options or V-port wedge designs to reduce turbulence and provide stable, proportional flow regulation across various open percentages.
- Smart PLC Integration: Compatible with MODBUS, Profibus, or HART protocols, allowing real-time status feedback, remote troubleshooting, and automatic stroke limit adjustment.
- Zero-Leakage Bi-directional Sealing: Precision-ground wedge seating faces ensure zero-leakage shut-off even in high-pressure differential applications.
Target Applications & Industries
Our control gate valves are deployed in high-capacity fluid lines requiring automated regulation:
- Municipal Water & Wastewater: Pumping station flow control, main distribution, and raw water intake.
- Oil & Gas Refineries: Hydrocarbon storage transfer, crude oil pipeline flow balancing.
- Power Plants & HVAC: Cooling water circulation, low-pressure steam regulation, and boiler feed lines.
Frequently Asked Questions (FAQ)
Q1: What is the difference between an ON/OFF gate valve and a control gate valve?
An ON/OFF gate valve is only designed for fully open or fully closed service. A control gate valve features heavy-duty modulating actuators, anti-vibration trim, and positioners to safely operate at partial openings for continuous flow regulation.
Q2: What control actuator brands can be integrated?
We supply built-in intelligent actuators and can also customize mounting flanges (ISO 5210 standard) to accommodate customer-specified actuator brands such as Rotork, AUMA, or SIPOS.
Q3: Can Oucang Valve customize pressure ratings and face-to-face dimensions?
Yes. As a direct manufacturer, Oucang Valve provides custom face-to-face lengths (API 600 / DIN 3202), high-pressure ratings, and matching companion flanges.
