Proportional pressure valves
Vickers by Danfoss three-way pressure-reducing/relieving valves set output pressure as a function of electric current, regardless of system pressure or flow. For pressures up to 350 bar [5,000 psi] and flows up to 400 l/min [106 US gal/min], these valves are often used for the position control of a single-acting cylinder, height control of a combine header, pressure control of a clutch or brake, or pilot signaling of a directional control valve.
