Function

High-precision positioning: After receiving pneumatic signals, it can precisely drive the cylinder actuator, overcome the influence of valve packing friction, medium pressure fluctuations, etc., with small positioning errors, ensuring the stability of valve opening, and thereby stabilizing the flow and pressure of the fluid in the pipeline.

Multi-mode adaptation: Supports range control, can switch between forward and reverse action modes, and is equipped with cams with freely selectable characteristics, which can adapt to valve and pipeline systems with different control logics and flow characteristics.

Stable gas path compatibility: Compatible with a wide supply pressure range of 1.4-7kgf/cm², the output pressure can meet the requirements of high-pressure cylinder actuators, with low gas consumption, reduced gas source loss, and ensuring the economic efficiency of continuous operation.

Convenient monitoring and maintenance: Reserved pressure gauge interfaces can monitor the gas line pressure in real time, facilitating staff to quickly identify gas line or valve location faults and reducing maintenance costs.

Application scenarios

It is highly consistent with the application scenarios of the same series NS737D-C, focusing on areas with high fluid control requirements:

In the Marine field: It is compatible with cargo oil pipelines, ballast water systems, and fuel delivery pipelines on ships, controlling the opening degrees of butterfly valves, ball valves, etc., to ensure the accuracy of fluid transportation and regulation during navigation.

Petrochemical industry: It is used for the feed pipeline of reaction vessels and the finished product conveying pipeline, precisely controlling the medium flow rate, and meeting the fluid proportioning and pressure stability requirements of multiple processes in chemical production.

General industrial pipelines: Suitable for steam, clear water and other medium pipelines in industries such as power and water treatment. When paired with double-acting actuators, it can achieve automatic valve control and enhance pipeline operation efficiency.
