Manual Valves

We design and manufacture high-performing manual valves, including Ball Valves, Gate Valves, Globe Valves, Check Valves, Plug Valves, and Butterfly Valves. We also have a dedicated PTFE / PFA lining facility for PTFE / PFA-lined valves, Pipe Spools, Pipe fittings, and associated equipment for high-corrosive/chemical applications.

How To Choose Manual Valves?

Selecting the right manual valve depends on your system’s pressure, flow control needs, and application type. Here’s a quick guide to help you decide:

1. Understand Your Application Requirements

Choosing the right manual valve starts with clearly understanding what the valve is expected to do in your system. Are you looking to simply open or close the flow (on/off control), regulate the flow rate (throttling), or prevent backflow? Each function requires a specific type of valve. For example, ball and gate valves are excellent for on/off control, while globe valves are ideal for throttling. Check valves are used to stop reverse flow, and plug valves work well with thick or slurry-like fluids. Clarifying the purpose upfront helps narrow down your options and ensures you’re selecting a valve built for that task.


2. Know Your Media (What’s Flowing Through the Pipe)

The fluid or gas passing through your system—also known as the media—has a major impact on valve selection. Some valves handle clean water or air easily, but harsh chemicals, steam, or abrasive slurries require corrosion-resistant materials and more robust designs. For instance, stainless steel or forged steel is commonly used for high-temperature or high-pressure applications, while specialty coatings or internal linings may be needed for chemical resistance. Always choose a valve material that’s compatible with your media to prevent premature wear, corrosion, or failure.


3. Consider Pressure and Temperature Ratings

Manual valves are designed to operate within specific pressure and temperature ranges. Exceeding these limits can result in leaks or system damage. Always check the valve’s pressure rating (measured in PSI or bar) and temperature tolerance to ensure it matches your system’s operating conditions. For high-pressure steam systems, forged steel gate or globe valves are preferred. In contrast, butterfly valves may be better suited for low-pressure applications with large diameter piping. Following API or ASME standards helps ensure the valve is safe and effective for your intended use.


4. Evaluate Flow Control Needs

Different valve types manage flow in different ways. Ball valves are best for quick shut-off with little flow resistance. Gate valves are excellent when you need full open or full close operation but are not ideal for throttling. Globe valves, however, provide precise control over flow rate and are commonly used where modulation is needed. Butterfly valves offer a lightweight and space-saving solution, often used in large pipelines. Understanding how much control you need over the flow will help determine the most appropriate valve type.


5. Select the Right Valve Type Based on Function

Each valve type has specific strengths depending on your system’s needs:

  • Ball Valves: Excellent for quick shut-off and high-pressure applications.

  • Gate Valves: Best for full isolation in pipelines with infrequent operation.

  • Globe Valves: Designed for flow regulation and frequent adjustment.

  • Check Valves: Automatically prevent reverse flow, protecting equipment.

  • Plug Valves: Ideal for viscous or abrasive media like slurries or chemicals.

  • Butterfly Valves: Lightweight, cost-effective, and great for large diameter systems.

Matching the valve type with its ideal use case helps you get the best performance and reliability.


6. Check for Compliance & Quality Standards

Industrial valve applications require strict adherence to performance and safety standards. Always ensure the valve you choose complies with recognized certifications like API 600 or 602 for gate valves, ASME B16.34 for pressure-temperature ratings, and ISO 9001 for manufacturing quality. These certifications verify that the valve has been tested for durability, reliability, and performance under demanding conditions, giving you peace of mind and preventing costly system failures.


7. Maintenance and Accessibility

Manual valves should be easy to operate and maintain over time, especially in critical or hard-to-reach areas. Consider features like low torque operation, extended stem designs for buried service, or top-entry configurations that allow for easier internal access. Also, think about whether spare parts like seats or seals are readily available. Selecting a valve that balances performance with simple maintenance will save time and cost in the long run—especially in systems that require regular inspections or servicing.
