OKEManual Control Valve Working Principle

Manual control valves are components used in pipeline fluid transport systems to control the flow of media. They can alter the channel cross-section and the direction of media flow, providing functions such as diversion, shut-off, regulation, throttling, check,分流, or pressure relief through overflow. Manual control valves typically consist of parts such as the valve seat, valve disc, valve stem, valve cover, and valve body.

OKE ManualControl Valve Performance Characteristics

The main performance characteristics of manual control valves include improving heating supply conditions, saving energy, and enhancing the hydraulic conditions of the pipeline network. They can adjust flow according to design conditions, achieving optimal temperature conditions, and offer better regulation performance than gate valves or globe valves, with an approximately linear regulation characteristic. Additionally, manual control valves can manage flow based on rated capacity, reducing excess flow in the pipeline network and improving the operational conditions of water pipes.

OKEManual Control Valve Installation and Use

Installation of manual control valves requires attention to multiple aspects, including ensuring that the installation position, height, and inlet/outlet direction comply with design requirements, and that connections are secure and tight. For manual valves installed on insulated pipelines, the handle must not face downward. Valves must undergo visual inspection before installation to ensure that the nameplate meets national standards. Strength and tightness performance tests should also be conducted before installation, and only after passing these tests can they be used.

OKECorrect Operation of Manual Control Valves

Correct operation of manual control valves is crucial for ensuring the continuity and safety of the process. Maintenance and care of manual control valves

Maintenance and care of manual control valves are equally important to ensure their long-term stable operation. This includes regular inspection of the valve's sealing performance, cleaning the valve body and seat, and replacing worn parts as necessary. Proper maintenance and care can significantly extend the service life of manual control valves.

In summary, manual control valves are indispensable components in pipeline systems, and their correct installation, use, and maintenance are vital for ensuring system safety and efficiency.
