Ball valves are favored for their reliability and ease of use. They have a quick shut – off capability, making them ideal for situations where frequent operation is necessary, and are typically made from durable materials like brass or stainless steel. They can handle high pressures and resist corrosion, ensuring their functionality in demanding underground environments.
These valves have two functions. They can control both water flow and drainage, which is essential for preventing freeze damage in outdoor plumbing systems, especially in irrigation setups. Commonly used in low – pressure systems, stop – and – waste valves allow for manual drainage after the water supply has been shut off.
Plug valves are small but strong. They are suitable for diverse fluid types and pressures and offer reliable shut – off and precise flow control. This makes them an excellent choice for underground systems. Usually made from materials resistant to corrosion and abrasion, plug valves can maintain their performance even in challenging environments, ensuring long – term durability.
The primary function of check valves is to prevent backflow, ensuring that water flows in only one direction. This is crucial for maintaining the efficiency and safety of underground water systems. Check valves prevent water from flowing backward, which helps avoid damage and ensures the water distribution network works properly.
Underground water shut-off valves play a critical role in controlling water flow within pipelines. Effective flow control is crucial for maintaining the water distribution network and preventing accidents caused by uncontrolled water flow.
In addition to controlling water flow, some underground shut-off valves are designed to control water pressure within the system. By maintaining the pressure within safe limits, these valves help prevent damage to the infrastructure and equipment.

Gate valves control water flow by lifting or lowering a metal gate, allowing for a full-open or full-closed position. These valves are highly durable and can withstand harsh underground conditions over long periods. They handle high water pressures and temperature variations well, making them ideal for main water shut-offs where infrequent operation is expected. However, frequent use can cause wear and tear on the gate mechanism, leading to potential leaks and reduced performance.
Plug valves use a rotating cylindrical or tapered plug to control water flow. These valves are compact, versatile, and offer reliable on/off control. They are well-suited for applications requiring precise flow control and can handle different fluid types and pressures. Nevertheless, without additional support, they may not be suitable for high-pressure or high-temperature conditions.
Ball valves use a rotary ball with a hole through its center. When rotated, the hole aligns with the pipeline to allow flow or blocks it when perpendicular. These valves offer quick shut-off capabilities, are durable, and need minimal maintenance. They are ideal for frequent use and increasingly popular for main water shut-offs. However, in certain environments, they can suffer from dezincification corrosion, which may affect their performance and lifespan.
Check valves are essential for preventing backflow, maintaining system integrity, and ensuring safety in applications where flow direction control is crucial. These valves typically use a flap or a disc that opens when water flows in the correct direction and closes to prevent backflow. While they are crucial for controlling flow direction, they generally do not have control handles for manual operation, which can be a limitation in some situations.
Stop-and-waste valves serve a dual purpose: stopping water flow and draining excess water from pipelines. This functionality is especially useful for protecting against freeze damage. These valves offer reliable water shut-off and drainage, making them crucial for outdoor systems in cold climates. However, due to their specific functionality, they may not be suitable for all underground applications.
