What Is A Hand Valve?

Hand Valve is a valve that requires manual intervention to achieve on-off control. It can change the flow direction or size of the fluid in the pipeline, and has the functions of diversion, cut-off, regulation, throttling, check, shunt or overflow relief. It is an important fluid control element.

The working principle of Hand Valves is usually to operate the valve opening and closing by mechanical means such as rotation or lever. When the valve is open, fluid can flow through the valve; When the valve is closed, the fluid is prevented from flowing. According to the needs of specific applications, Hand Valves can be operated in a variety of ways, such as hand wheels, handles, levers, sprockets, etc.

There are many kinds of Hand Valves, which can be divided into ball valves, plug valves, butterfly valves, hand wheel valves, etc. Each valve has its own unique characteristics and applications, such as ball valves for liquid and gas pipeline switch control, plug valves for low and medium pressure liquid and gas pipeline switch control, butterfly valves for low and medium pressure liquid and gas pipeline control.

Marine Hand Valves are usually installed in the ship's piping system to control the flow and shutdown of liquids. According to the needs of the specific application, the Hand Valve can be installed at the inlet and outlet of the pipeline, the outlet of the pump, and the oil tank.

When choosing to purchase a Marine Hand Valve, it is necessary to consider factors such as its applicability, reliability and economy. Specifically, factors such as the working pressure of the Hand Valve, the size of the interface, and the type of media need to be considered. At the same time, it is also necessary to consider the sealing performance, corrosion resistance and safety performance of the manual valve.

When installing Marine Hand Valves, it is necessary to follow the relevant specifications and requirements to ensure that the Hand Valves can work normally and extend their service life. At the same time, it is also necessary to check and maintain the Hand Valve regularly to discover and solve potential problems in time to ensure its safe and reliable operation.
