Automatic Recirculation valves
ARC Valve Disign
EDVC 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 any times.This is very important could pretect thecentrifugal pumps from permanently damaged if run dry when suffer from over heating and cavitation condition.
ARC Valve Principles
There are main line and bypass line outlet working principles. When there are sufficient flow through the valve, internal valve disc in the main line stay on an open mode. Dereasing flow through the valve caused the spring loaded disc to its seat closing the process outlet. Simultaneously, a bypass outlet is uncovered allowing a minimum flow of liquid back to teh pump.
Pressure reducing valve
EDVC is suitable for bypass with medium or low pressure, maximum pressure differential is 6MPa, and specific choice is determined by factory. Unique L bypass can eliminated noise by made high-speed flow medium, and prevent cavitation.
Characteristics
• Multi-cage type bypass, low noise, suitable for medium and low pressure working conditions.
• Forged valve body, can choose carbon steel or stainless steel material, etc.
• Standard bypass non-return function, maximum working pressure differential is 6MPa.
• With venturi port main flow non-return structure, adapt to complicated conditions.
• Pressure grade from PN16 to PN100, diameter from DN2to DN500.
• Can select manual bypass operation function, used in fault.
