Durable and Long-Lasting Gate Valves Delivered Fast Anywhere in Australia
What are gate valves, how do they operate and what are their uses?
Gate valves are used to isolate a substance - be it gas or fluid - in a line by the turning off of a wheel that is usually operated by hand though they can be used with other kinds of actuation. Essentially a gate (or block) is lowered into the pipe using a rising or non-rising system. Material utilised in their production may be cast steel, stainless or brass depending on type.
Gate valves can last for decades if they are not in regular contact with corrosive materials but if they are may need far more frequent replacement. When looking for gate valves in Australia look for products that are fully tested and certified to industry standards.
Mostly delivery of valves under 5 kg can be made to metropolitan areas the next day though country delivery by road freight may take an average of three days or longer.
Types of gate valves and specific qualities to look out for:
Types of Gate Valves:
1. Rising Stem Gate Valve:
The stem rises above the valve when the valve is opened.
Suitable for applications where valve position visibility is necessary
2. Non-Rising Stem Gate Valve:
The stem does not rise above the valve when opened.
Ideal for applications with limited vertical space.
3. Solid Wedge Gate Valve:
Uses a solid wedge as the gate, which is more durable and suitable for more robust applications.
4. Flexible Wedge Gate Valve
The wedge is split into segments to accommodate changes in the seat angle due to thermal expansion.
Qualities to Look for When Purchasing Gate Valves:
1. Valve Material:
Choose materials suitable for the fluid and environmental conditions (e.g., stainless steel, carbon steel, brass).
2. Pressure and Temperature Ratings:
Ensure the valve can withstand the maximum pressure and temperature of your application.
3. Size and End Connections:
Select the valve size and end connections (flanged, threaded, welded) that match your piping system.
4. Operation Type
Determine whether manual (handwheel, lever) or automated (actuator) operation is needed based on operational requirements.
5. Sealing Mechanism
Check the sealing mechanism (solid wedge, flexible wedge) to ensure it suits your application’s demands for sealing efficiency.
6. Compliance and Certification
Verify that the valve complies with relevant standards (e.g., Australian Standards AS/NZS) and holds necessary certifications (e.g., ISO certification).
7. Durability and Maintenance:
Evaluate the valve's expected lifespan and ease of maintenance (availability of spare parts, accessibility for servicing).
8. Supplier Reputation and Support:
Choose a reputable supplier known for quality products and reliable customer support.
9. Cost and Value:
Consider the initial cost along with long-term value, including factors such as energy efficiency and operational reliability.
By considering these factors, you can ensure that the gate valve you choose is suitable for your specific application needs in Australia, whether it's for industrial, commercial, or residential use.
