What is an arc valve?

An automatic recirculation valve (ARC valve) is a multi- functional valve whose primary purpose is to ensure that a pre-determined minimum flow is assured through a centrifugal pump at all times.

How does a yarway valve work?

The sensing system responds to changes in flow rather than pressure. The control valve incorporates a pressure reducing device that divides recirculation flow and guides the resulting streams through successive 90° turns to dissipate the destructive energies of high pressure while controlling fluid velocity.

What is recirculation valve?

Automatic recirculation valves, sometimes referred to as pump protection valves or minimum flow valves are installed on the outlet of a centrifugal pump discharge line. Their purpose is to prevent the pump from overheating by ensuring that there is a minimum flow through the pump at all times.

What is bypass valve?

A bypass valve is a type of valve that is installed in a bypass pipeline. Therefore, valves that are installed on the bypass piping line, such as pressure reducing valves, steam traps and control valves, are also known to be bypass valves.

What is an ARV pipe?

Air release valves (ARVs) are used to help resolve air entrapment issues. ARVs are typically located at high point elevations in force mains. The ARV released any entrapped air caught at the high point of the system (see image below 1).

How does a minimum flow valve work?

A minimum flow aids the cooling of the bearings and the seals within the pump and reduces the potential for a continuous stop/start situation. The valve maintains a minimum flow through the pump, whilst also acting as a non- return check valve for the pump.

What’s the difference between recirculating dump valve?

A recirc valve does a very similar job to a blow off valve, the key difference is that a recirc valve recirculates the excess pressure back into the intake, instead of out into the atmosphere. This, in turn, helps your turbo setup retain psi level better between shifts, and gets rid of turbo flutter.

What is the purpose of a bypass valve?

The bypass valve – otherwise known as a pressure relief valve – is an integral part of the oil filter. The valve is designed to open when the oil filter becomes clogged or when the oil is too thick. This allows the oil to bypass the filter through a center tube.

What is a bypass valve turbo?

A compressor bypass valve (CBV), also known as a pressure relief valve or diverter valve, is a manifold vacuum-actuated valve designed to release pressure in the intake system of a turbocharged vehicle when the throttle is lifted or closed. This type of valve is typically an aftermarket modification.

What is the long form of ARV?

ART stands for antiretroviral treatment. It is also called combination therapy or HIV treatment. What are ARVs? HIV drugs are called antiretrovirals (ARVs) because HIV is a type of virus called a retrovirus.

Why is deadheading a pump bad?

Deadheading means you shut off the pump’s ability to discharge fluid by closing a valve. The fluid will churn inside the pump until it heats into a vapor. The pump’s impeller is now receiving little to no fluid, usually causing irreparable damage.
