Types of Valve Exercising Machines
Valve exercising machines come in various forms, each designed for specific applications within water management systems. Understanding the different types helps organizations choose the right tools for their needs.
Mounted Valve Operators
Mounted valve operators are essential for maintaining valves that are difficult to reach. A prominent example is the ERV-750 from Wachs Utility Products, renowned for its extendable arm that can reach up to 13 feet. This type of valve exerciser is ideal for curbside valve boxes and hydrants, allowing operators to exercise multiple valves without relocating equipment. The dual pivot points provide flexibility, ensuring effective operation even in challenging locations.
Handheld Valve Operators
Handheld valve operators, such as the Wachs Pow-R-Drive 2, are crucial for organizations that deal with a high volume of valves. These tools enable operators to exercise valves manually, reducing the risk of damage from excessive force. The portability of handheld models makes them perfect for everyday use, especially in hard-to-reach areas. They also feature electronic torque control, enhancing safety and efficiency.
Portable Valve Exercisers
For confined or limited spaces, portable valve exercisers are the optimal choice. These compact devices can easily be maneuvered by a single operator, allowing for quick valve cycling. The Wheeler-Rex ValveMaster is an example of a portable exerciser that balances design and functionality, making it an excellent addition to any water utility’s toolkit.
Heavy-Duty Valve Exercisers
Heavy-duty valve exercisers, such as the TM-7 HD Plus, are designed to handle stubborn valves that may not have been exercised regularly. These machines deliver high torque, making them suitable for large valves ranging from 6 inches to 60 inches in diameter. They are often equipped with advanced features like Bluetooth for data communication and are compatible with various logging programs, ensuring that operators can maintain accurate records of valve performance.
Electric and Pneumatic Operators
Electric and pneumatic valve operators enhance the efficiency of valve exercising, particularly in industrial applications. These machines can support a range of valve types, including non-rising and rising stem valves. Their design focuses on quick operation and improved operator safety, significantly reducing the risk of injury associated with manual valve handling.
