When it comes to industrial valve applications, choosing the right valve type is crucial for ensuring system efficiency and longevity. Underground gate valves, cast iron butterfly valves, and dual disc check valves are popular choices, each offering unique benefits. But what sets these valves apart, and how do they serve different needs? Let’s explore their features and why you might choose one over the other.
Underground Gate Valve: The Ultimate Solution for Subsurface Systems
An underground gate valve is designed specifically for controlling the flow of fluids in subsurface applications like municipal water supply systems, natural gas pipelines, and oil refineries. This valve gets its name from the gate-like mechanism that controls the fluid flow. The gate, typically made of metal, moves perpendicular to the fluid flow direction. When the gate is lowered, it blocks the flow, and when raised, it allows the fluid to pass through.
Key features of underground gate valves include:
Material Durability: Often made from cast iron or similar robust materials, these valves are designed to withstand harsh underground conditions, including pressure changes and soil movements.
Variety of Sizes: Available in a range of sizes from DN25 to DN1200, these valves can be customized to fit specific pipeline dimensions.
Multiple Actuation Options: These valves can be manually operated or equipped with actuators like electric or pneumatic systems, making them versatile for various applications.
For industries looking for reliable solutions in buried pipelines, the underground gate valve is a top choice. As a leading manufacturer, we offer OEM & ODM services, wholesale options, and can tailor valves according to your exact specifications.

Cast Iron Butterfly Valve: A Versatile and Cost-Effective Option
The cast iron butterfly valve is widely used in applications where space is limited and quick operation is essential. Unlike the gate valve, the butterfly valve operates by rotating a disc within the flow path. This disc, positioned in the center of the pipe, is connected to an actuator on the outside of the valve.
Here’s why you might choose a cast iron butterfly valve:
Compact Design: Its small size and lightweight nature make it ideal for installations where space and weight are considerations.
Quick Operation: The 90-degree rotation of the handle or actuator allows for rapid opening and closing, making it suitable for applications requiring frequent operation.
Material Options: While cast iron is a common choice, these valves can also be made from other materials, depending on the application’s temperature and pressure requirements.
Whether used in HVAC systems, water treatment plants, or industrial processes, cast iron butterfly valves provide efficient flow control with minimal maintenance. Our extensive range of butterfly valves includes options for various applications and industries. We also offer customized solutions and welcome local wholesalers and suppliers to contact us for competitive pricing and support.
A dual disc check valve is essential in systems where preventing backflow is critical. This valve type uses two spring-loaded discs that close against the flow direction, ensuring that the medium only flows in one direction. The dual disc check valve is particularly beneficial in applications involving water, oil, or chemicals.
Advantages of the dual disc check valve include:
Compact and Efficient: Its slim design allows for easy installation between flanges, making it a space-saving solution.
Wide Range of Applications: These valves can handle various media, including aggressive chemicals and high-temperature fluids, thanks to their robust construction.

There are two main designs to consider when selecting a check valve for axial flow applications in piping systems (we also call it axial flow check valve). They are single-disc or poppet-type valves and double-disc check valves. Both types allow flow in one direction while preventing back-flow. However there are some key differences in their operation and suitability for various services that need to be understood.
How Single Disc Valves Work
In a single-disc check valve (also called a poppet valve), a circular disc or “poppet” rests against the orifice. Fluid enters axially around the disc, opening it from its seat. When reverse flow occurs, the valve disc drops and closes under the action of gravity or fluid force to prevent reverse flow.
Pros of Single Disc Valves
Simple and economical design without springs or hinges.
Compact inline footprint fits into tight spaces.
Lightweight poppet responds quickly to flow changes.
Low popping pressure opens easily with minimal headloss.
Cons to Consider
Susceptible to disc bouncing at low flows or very rapid reversals.
Prone to water hammer damage if used with rapidly closing valves.
Minimal flow capacity – best for smaller pipe sizes.
Disc can hang up on debris and not reseat fully.
Dual Spring-Loaded Disc Operation
The two adjacent discs in a double disc check valve are held closed on the valve body by a coil spring. On forward flow, pressure forces the discs apart as they pivot on pin hinges. Instead, countercurrent pushes them closed, and the increased pressure compresses the springs.
Benefits of Dual Disc Design
Very positive closure, less sensitive to transient pressures.
Spring wear could reduce closing capability over time.
Overall, the single disc valve is a good budget choice for clean flow service or low pressure rise applications under 3 inches. However, dual disc check valve provides smoother operation and is suitable for higher flow rates, tighter containment requirements or debris handling in larger pipes. When choosing between two axial check valve types, please consider flow rates, fluid characteristics and installation space.
