Product details

Danfoss MCV116A3204 Electronic Pilot Pressure Control Valve

Product Overview

Danfoss MCV116A3204 is a high‑performance Hydraulic valve, also known as PCP (Pressure Control Pilot) valve from MCV116 series. Mounted directly on pump housing, this Hydraulic valve serves as core proportional control component for Danfoss 90 series variable displacement piston pump. It converts 4‑20 mA electric signal into proportional pilot differential pressure to adjust pump swash‑plate angle and regulate pump displacement and output flow. It guarantees precise electronic remote adjustment for complete hydraulic system, widely used for original assembly, equipment overhaul and spare‑parts replacement of mobile construction Machine.

Working Principle

Electric controller sends 4‑20 mA control current to this Hydraulic valve. Internal torque motor deflects according to current magnitude, changing nozzle‑flapper clearance and generating proportional pilot differential pressure. Pilot pressure acts on pump servo piston to swing swash‑plate, so as to change displacement and flow of main hydraulic pump. Larger input current brings larger pump output flow; smaller current reduces flow output. Built‑in closed‑loop hydraulic feedback compensates disturbance caused by load and oil temperature, keeps control accuracy and protects whole hydraulic system from abnormal pressure fluctuation of construction Machine .

Core Advantages

1. Professional mobile‑hydraulic closed‑loop nozzle‑flapper design, fast response and excellent linearity, realizes stepless proportional flow adjustment for main pump of engineering Machine.

2. Excellent anti‑shock and anti‑vibration capability, adapts to severe vibration environment of construction‑site Machine.

3. Standard pump‑head mounting interface; original and qualified replacement parts are directly interchangeable, convenient for field disassembly and maintenance.

4. Better contamination tolerance than general servo valves, lowers failure risk for on‑site hydraulic system.

5. Adopts industry‑standard 4‑20 mA signal, easy to connect with PLC and industrial controller for automation upgrading of Machine.

Application Range

Danfoss MCV116A3204 Hydraulic valve is an essential proportional pilot accessory for Danfoss 90 series piston pump. It undertakes electronic displacement‑adjustment task inside mobile hydraulic system. Widely supplied for machinery repair workshops, construction‑site maintenance and global aftermarket spare‑parts business for road construction and mining Machine.
