T-MATS: Valve Library Block
This block simulates the performance of a valve using basic thermodynamic equations, properties, and table lookups.

Valve Inputs:

Valve Input	Description
ByGasPthCharIn	Gas Path Characteristics of the Bypass, 5x1 vector consisting of: - W - gas path flow [pps] - ht - enthalpy [BTU/lbm] - Tt - Total Temperature [degR] - Pt - Total Pressure [psia] - FARc - Combusted Fuel to Air Ratio [frac]
ValvePos	Valve Position[frac] 0 - full closed command, 1 - full open command
MFPGasPthCharIn	Gas Path Characteristics of the Main Flow Path, 5x1 vector consisting of: - W - gas path flow [pps] - ht - enthalpy [BTU/lbm] - Tt - Total Temperature [degR] - Pt - Total Pressure [psia] - FARc - Combusted Fuel to Air Ratio [frac]
Nmech	shaft speed [rpm]

V_Data	Valve internal calculation Data

Valve Mask Variables:

Valve Mask Variable	Description
VFO_M	Valve fully open Value[frac], mechanical valve limit
VDZ_M	Valve dead zone Value[frac], mechanical requirement before valve begins to move off fully closed
VAe_M	Valve Active Area[in^2], size of valve opening
X_VPRVec_M	Valve Pressure Ratio Vector (x-axis)
T_VWArray_M	Valve Flow Array (W=f(PR))

Note: Vectors are the x and/or y axis to a table made of an array.
