Control valves are used for controlling process variables such as flow, pressure, level or temperature in a process plant to ensure the quality of the end product. Hence, correct sizing and selection is critical to ensuring the required outcome.
At Winnellie Valve and Process, we carry an extensive product range of quality Control Valves in a range of design types to suit all applications. If you’re looking to buy the most comprehensive range of Control Valves in Australia, you need look no further than our premium collection.
We have many years of experience in selecting the right valve for your application. Our Control Valves product ranges are available with:
Control valves are used to regulate the flow of fluid through a system as you modify the valve plug or disc with an actuator. They are brilliant at maintaining a steady flow rate, temperature and pressure as well as other variables such as concentration, density and liquid level.
Control Valves are used to vary the rate of flow passing through a system. The valve stem moves, altering the size of the passage and this increases, decreases or holds steady the flow. The Control Valve opening is altered whenever the process parameter being controlled is unequal to the value it is meant to be (called a set point).
Control Valves are integral to process systems across a wide range of industrial applications to control flow, whether in the oil and gas, petrochemical, pharmaceutical or other process-related utilities where control elements are necessary.
Types of control valves include High-Pressure Control Valves, V-port Ball Valves, Butterfly Valves, and Segmented Ball Valves. Control Valves come with three primary types of trim: Snap Trim (also called a Quick Opening Trim), Nominal Trim (also called Linear Trim) and Equal Percentage Trim. These are the operative parts that control the flow of liquid and gas through a valve.
There are a wide range of different Control Valves with different considerations for their purpose. When selecting a valve, it is important to check the pressure recovery characteristics of valves for the thermodynamic properties of the fluid. Characteristics to look for are what liquid or gas is flowing through the valve, valve size, valve body, trim materials, actuator type and valve flow characteristic. When it comes to valves, Winnellie Valves and Process will be able to talk you through what type of product is best suited to your needs so you acquire the best-fit valves for your application.

Installing a Control Valve is equally as important as choosing the right type of process control. The main variables you’ll want to consider are the design of the process, size of the valve(s) relative to the application and how accessible it is to install, repair and maintain. In the case of high-pressure gas or steam pressure-reducing applications, try to have only straight pipes downstream of the valve or use a long sweeping elbow to avoid additional pipe noise as well as to allow for drainage through the valve.
