This allows for the better transient modelling of sprinkler systems. The Transient Nozzle model has been improved, with the ability to be set as on or off, as opposed to simply having a 0 flowrate requirement. Y-Type Valve: Similar to globe valves, but instead of using an internal baffle, the gate mechanism is located at an angle to the flow, allowing frequent operation with less restriction on the flow.

Globe Valve: Typically used in pipelines, these consist of two halves of a valve body, separated by an internal baffle, where a plug closes in between the baffle. Gate Valve: These have a planar sealing surface between the valve gate and the valve seats, used when a straight line flow is required with minimum restriction. Diaphragm Valve: These consist of a rubber or plastic membrane which is pushed down to shut off flow in many process systems. Butterfly Valve: Consisting of a rotating disc, either flat or lenticular in nature, used in applications which require bi-direction tight shut-off. Ball Valve: Consisting of a rotary valve ball, this valve is also commonly used in many industries. Angle Valve: This is common in the oil/gas, power and shipbuilding industries, consisting of a controlled valve door around a 90 degree bend. With earlier versions of PIPENET Transient module, it was necessary for the user to input the valve characteristics themselves. The range of built-in valve models has been has been enhanced to provide powerful facilities. This is a new way of working with PIPENETs operating valve in the transient module, making the modelling of many common types of valve considerably easier. When the pressure on the plug increases above a specified set pressure, the valve opens until the flow pressure reaches the valves fully open pressure. The valve consists of a plug situated ahead of a spring or similar device.
