The ARC valve is very useful in protecting pumps that are used in various settings. Different manufacturers make valves. You will therefore be exposed to different types and designs of valves. However, the functionality is the same. These are just a few of the many options available for protective valves.
ZHD Minimum Flow Control Valve
This multistage minimum flow control valve uses a multilevel cage-symmetric sleeve. This valve has a medium velocity and is intended to reduce noise due to high steam pressure or gas pressure. It prevents liquid cavitations, making it an excellent choice for medium pressure high performance. You can use it with either a multi-spring diaphragm or pneumatic actuators.
ZDL Automatic Recirculation Valve
This series provides protection for centrifugal pumps during low-load operations. The bypass is opened completely when the pump flow level falls below the minimum threshold to allow for a flow path that maintains pump flow. This valve series is a multistage bypass pressure reducer and can be used for bypass with low to medium pressure differential. Manufacturers can help you select the right one for you.
ZDM Automatic Recirculation Valve
Another series is this one, which is intended to provide protection for the centrifugal pump through the bypass opening when there is low load flow on the pumps. The series has a 30MPa maximum differential pressure, compared to the 6MPa differential pressure of the ZDL series. The multistage decompression bypass reduces noise and prevents cavitation erosion damage.
ZDT Valve
This series can also protect the operation of centrifugal pumps. It is the same protection as other series but has a maximum pressure differential of 4MPa. This series is great for many applications. Your manufacturing factory can assist you in finding the best solution for your specific applications. It’s simple to assemble, reliable and stable in operation. It is easy to install on the pressure outlet of the pump and has few parts that can cause damage.
YB7 Pressure Valve
This back pressure valve can be used when the common control system is not available. It is a special pressure control valve that matches the automatic recirculation to protect the pump system. It regulates upstream pressure and can easily reach the technological set pressure value. It is resistant to corrosion and vaporization phenomena. It is easy to use and self-supporting.
You will want to ensure that the automatic recirculation device you purchase is suitable for your specific application. You should choose the right brand for your automatic recirculation valve. This will ensure that you get the best protection.
