PVG Hydraulic Multi-way Valve
The PVG Hydraulic Multi-way Valve (Danfoss PVG) is an efficient and stable control valve. The following introduces its specific content:
I. Basic Overview
The PVG multi-way valve is an advanced control valve developed by Danfoss, featuring various functions such as pressure control, temperature control, and flow control. It is widely used in various fields, such as refrigeration and air conditioning systems, hydraulic systems, and gas compression systems.
II. Working Principle
The PVG multi-way valve is characterized by its spool closed-loop control, combined with a pressure compensator, to achieve precise flow control. The electronic control module PVE is the core component ensuring precise control. By changing the current signal of the electromagnet, the position of the spool can be controlled, thereby changing the flow rate and pressure of the hydraulic oil to control the actuating element.
III. Product Series and Specifications
The mainstream PVG product series include PVG16, PVG32, PVG100, and PVG128/256, with flow specifications ranging from small to large to meet different application scenarios and needs. These series belong to the same platform and can be combined across series to maximize application requirements.
