CONTROL VALVES

Control Valves

DISTRIBUTOR VALVE – VDX 2500

The distributor valve REIVAX VDX2500 is a proportional directional control valve designed for hydraulic systems with pressure up to 100
bar.

Being a multiplier flow element, is used in large systems with flow rate up to 2500 l / min (Ap = 10 bar). It is a hydraulically piloted, which 

are embedded in the housing safety valves (electric, hydraulic and manual drives), the proportional control valve and the device
transduction position proportional directional valve 4-way, providing a compact construction and high safety.

Due to internal geometric features, enables precise and smooth control of the position of the spool, and contribute to the increased length
of intermittency pumps the hydraulic unit due to low internal leakage.

Distributor Valve
DISTRIBUTOR VALVE – VDX 7000

The distributor valve VDX 7000 is a directional proportional control valve designed for hydraulic systems with pressure up to 65 bar.

It is used in large system with nominal flow rate up to 7,000 l / min (Ap = 10 bar). It is configured as a hydraulically pilot operated proportional directional valve 4-way, controlled by a commercial proportional directional valve. Due to internal geometric features, enables precise and smooth control of the position of the spool, and contribute to the increased length of intermittency pumps the hydraulic unit due to low internal leakage.

Servoproportional Valve – VPX 30

VPX30 is a servoproportional valve designed to control distributor valves and hydraulic servomotors of hydro power plant’s governors.

Synthesizes several solutions providing a robust equipment, tolerant to oil contamination and with high dynamic performance.
