Automatic Recirculation Valve (ARC) Options

An ARC valve has proved to be very important in offering protection to pumps which are used in different kinds of settings. There are different manufacturers dealing in the making of valves. This means, therefore that you will be exposed to different types of the valves varying in their design, features, materials and sizes although the functionality is just the same. Here are some of the options that you have in the market for these important protective valves.

ZHD Minimum Flow Control Valve:

This is a multistage minimum flow control valve using a multilevel cage symmetric sleeve valve. It has a medium velocity valve and is designed to reduce noise through high steam or gas pressure within the valve. It effectively prevents liquid cavitations and is therefore an excellent choice for high pressure medium performances. It works with a multi-spring diaphragm mechanism or on pneumatic actuators, among others from which you can choose.

ZDL Automatic Recirculation Valve:

This series offers protection to the centrifugal pumps at low load operations. When the pump flow levels are below preset minimum levels, the bypass opens completely to offer a path that maintains the allowed pump flow. This valve series works on multistage bypass pressure reduction and it is suitable for bypass with low or medium pressure differential. The manufacturers can help you choose the specific one for your needs.

ZDM Automatic Recirculation Valve:

This is another series that is designed to offer protection to centrifugal pumps through the bypass opening during low load flows on the pumps. This series, however, has a 30MPa maximum pressure differential compared to the 6MPa maximum pressure differential of the ZDL valve series. With a multistage decompression bypass, noise from the high speed flow is eliminated and there is prevention of cavitation erosion damage and valve components braising.

ZDT Valve:

This series is also made to protect the functioning of centrifugal pumps the same as the other protective series but with maximum pressure differential at 4MPa. It is a great choice for different applications and your manufacturing factory can help you in getting the best for the applications that you have. It is simple in structure, stable and reliable in terms of operation. It has very few mobbing parts and it can be installed separately on the pump pressure outlet.

YB7 Pressure Valve:

This back pressure valve is used in conditions where the common controlling system cannot be used. It acts as a special pressure control valve to match with the automatic recirculation valve in terms of protecting the pump system. It controls upstream pressure and easily achieves technological set pressure value. It prevents corrosion and vaporization phenomena. Apart from being easy to operate, it is also very easy to maintain and is also self supporting.

When purchasing an automatic recirculation valve, you will need to make sure that you get the best for your application needs. Quality is important on an automatic recirculation valve for choosing your brand with care to enjoy the best protection from the choice you make.
