Description

The component TwoWayFlowControlValve is a model of a 2-way flow control valve. It maintains a largely constant outlet flow even at a variable (higher) inlet pressure.

If pressure difference pA - pB is less than Nominal pressure difference the valve acts like an orifice with the characteristics Nominal volume flow and Nominal pressure difference.

For all pressures exceeding Nominal pressure difference the valve keeps the flow constant with the given Deviation at Pressure difference @ Deviation.

In reverse flow direction the check valve becomes active.

The component TwoWayFlowControlValve is not a model of a flow control valve according to its physical structure. It merely represents the characteristic behavior of a flow control valve. Therefore dynamic effects such as forces due to inertia will not be represented.
