Pressure Control Valves

Valves for pressure control and relief

Use these blocks to model valves that control the flow pressure in a network.

Simscape Blocks

Pressure Compensator	Valve used to regulate the pressure drop across a hydraulic component
Pressure Reducing 3-Way Valve	Composite valve comprising the functions of pressure reducing and relief valves
Pressure Reducing Valve	Valve used to reduce pressure to a specified value
Pressure Relief Valve	Valve used to vent pressure in excess of a preset value from a hydraulic line

Featured Examples

Direct-Acting Pressure Relief Valve Test Rig

A test circuit built to check the pressure-flow characteristic of a direct-acting pressure-relief valve. The valve model consists of an orifice, a hydro-mechanical converter, a preloaded spring, and a hard stop.

Pressure-Compensated Flow Control Test Rig

A test circuit built to check the characteristics of a pressure compensator. A pressure source is connected to two flow paths, each with a fixed orifice and a variable orifice that acts as a variable load. Along one flow path a pressure compensator is installed.
