Flow Control Valve V-034
Flow control valves precisely regulate medium flow by altering the cross-sectional area of the flow passage or the position of the valve core. Consequently, they ensure stable flow control and maintain the system within preset requirements. These precision flow control valves are not only key components for adjusting medium flow but also play a crucial role in achieving system efficiency and stability. Its operating pressure range spans 200 to 350 bar (depending on size and material), with a temperature range from -20°C to +180°C. Construction materials include cast iron (for general applications) and stainless steel/aluminum alloy (for high-pressure or corrosive media).
Compared to conventional valves, flow control valves prioritize stable and precise flow regulation. They maintain constant flow even during pressure fluctuations or environmental variations, preventing disruptions to system stability. While globe valves open or close pipelines, flow control valves are specifically engineered for continuous, smooth flow regulation. Constructed from corrosion-resistant, high-strength materials with superior sealing structures, these valves ensure stable performance across diverse complex operating conditions. Featuring low maintenance requirements, they maintain system efficiency and steady flow with minimal pressure drop—even during pump startups or load changes—making them the ideal flow control solution for process installations.

Features
High-Precision Regulation
The V-034 valve incorporates a precision-machined spool or needle valve in its internal structure, enabling exact flow adjustment to meet the demands of systems with highly sensitive flow requirements.
Low Pressure Drop Characteristics
Through fluid dynamics optimization, this valve minimizes fluid flow resistance. This low-resistance feature protects pump efficiency and reduces energy costs in hydraulic and process systems. Additionally, the valve's internal passage design ensures minimal pressure drop across the valve.
Superior Sealing Performance
The flow control valve incorporates wear-resistant and heat-resistant sealing components, effectively preventing leakage and ensuring stable operation in high-pressure or corrosive media environments.
Low Maintenance Costs
The V-034 features a simple structure with easily replaceable components, supporting online maintenance without requiring shutdown or pipeline disassembly. This reduces equipment downtime and lowers maintenance expenses for plant engineers.

Applications




The hydraulics high-precision flow control valve can be used to control the speed and motion of actuator and cylinder. Its low pressure drops preserves pump efficiency and improves equipment response.
A needle flow control valve can be utilized in metering, dosing, and proportional control loops of assembly lines. Precise regulation gives a uniform quality of the product with every production run.
The corrosion-proof flow control valve is suited for corrosive and high-viscosity fluids when manufactured in suitable materials and sealings. It regulates bypass flows, recirculation, and feed-rate control for safe and uniform processing.
Valve is also suitable for chilled-water balancing, pump bypass, and flow metering in utility systems. Low maintenance and tough seals reduce downtime for building operators.

Support


Before installing low-dropout valves, completely isolate and drain the pipeline section. Valve specifications, materials, and thread types (BSP, NPT, or G) must match the piping system. Clean the pipeline to remove contaminants and install inlet filters at locations where particulate matter may be present. When installing flow control valves, ensure all flow direction arrows point toward the system fluid flow direction. Threaded connections require manual initial tightening to prevent misalignment; use compatible thread sealant or flange gaskets at bolted joints. Support adjacent piping to prevent additional loads on the valve body. For pilot-operated or electric actuator designs, keep the actuator and control lines exposed. Set the initial flow rate after gradual pressurization, then inspect for leaks and verify flow stability. Re-verify torque values after initial operation.
