WSV Manual Valve
Manual valves are those valves that operate through a manual operator, such as a handle lever, handwheel, or Gearbox. They are a control part of the pipeline flow system. Manual operated valves can be divided into many types, manual three-way valve is one of the most common types. The manual regulating valve can be used in many circumstances and various usages. For instance, there are manual air/gas shut-off valves, manually actuated valves for remote manual valve operation, manual selector valve, manual block valve, manual bypass valve, etc. Wedouli is a professional manual valve manufacturer that able to offer different types of manual hand valve.

Manual valves are mainly used to stop and start flow(shut off or on-off valves), although some designs are available for basic manual throttling. The best manual on-off services are those that allow flow to pass directly through the valve body, with a full are closure element that presents little or no pressure drop. Then manual operators are usually placed in the middle stroke position. Even though a manual on-off valve is being used for basic throttling, it is not considered a control valve due to it is not part of a process loop, which requires some type of self-actuation as well as input from a controlling device to the valves.
Many different types of industrial valve are used in industrial applications worldwide.
Weidouli valves offers a variety of manual valves, including ball valves, gate valves, butterfly valves, plug valves, globe valves, check valves, discharge valves and strainers to meet core competencies of quality, cost and delivery time.
A ball valve is a shut-off valve that controls the flow of a liquid or gas through rotary ball have a bore. The medium can flow or be blocked by rotating the ball a quarter turn (90 degrees) around its stem.
A gate valve is generally used to completely shut off fluid flow or in the fully open position, provide full flow in a pipeline.
A butterfly valve is a quarter-turn rotational valve, that is used to stop, regulate and start flow.
A plug valve uses a rotating plug inside of body to control fluid flow, shaped like a cone or cylinder.
A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipe.
A check valve is a device that only allows the flow of fluids in one direction and is commonly referred to as non return valves or one way valves.
A discharge valve is a device for monitoring and control flow through a circulation system.
A strainer is typically used in applications where the number of solids to be removed is small, and where frequent clean-out is not required.
