Brass ball valves are key parts in water-based fire protection systems, delivering reliable, precise flow control when it matters most. Designed to withstand high pressures up to 300 PSI or 600 PSI, these valves are ideal for fire sprinkler systems, industrial applications, and non-potable water supply lines. Built from cast brass with durable seals and optional stainless-steel components, they ensure long-lasting performance in demanding environments.
Whether you need to stop water flow or drain water from a system, QRFS offers high-quality fire protection valves engineered for precision and durability.
Ball valves use a rotating ball with a full port design to provide minimal restriction and efficient flow control. These valves are widely used in fire protection systems because they allow for quick shut-offs and consistent performance under high working pressures.
Their threaded connections make installation simple across a variety of industrial, gas, and fire protection applications.
Our brass ball valves are specifically designed for fire sprinkler systems and related applications. Many models are UL Listed and FM Approved, ensuring compliance with industry standards. These valves are commonly used in trim and drain applications on fire sprinkler systems, as well as other non-potable water systems.
Fire protection ball valves must perform reliably under demanding conditions. QRFS valves are engineered to handle high pressures, making them ideal for large-scale systems and critical infrastructure. Their robust construction supports long-term use in industrial and commercial settings where consistent performance is non-negotiable.

What is a ball valve, and how does it work?
A ball valve is a flow-control device that uses a rotating ball with a hole through its center to regulate water movement. When the handle is turned, the ball aligns with the pipe to allow flow or rotates perpendicularly to stop it completely. This simple quarter-turn operation makes ball valves fast and reliable for shutoff applications.
Why are ball valves used in fire protection systems?
Ball valves are commonly used in fire protection systems because they provide quick shut-off and dependable performance. They are often installed in drain lines, test lines, and various sprinkler system trim applications to control or stop water flow efficiently.
What role do ball valves play in fire sprinkler systems?
In fire sprinkler systems, ball valves help control, isolate, and direct water flow to critical components. They are frequently used for draining systems, testing equipment, and shutting off water to a device during maintenance. These functions ensure the system operates properly and can be serviced safely.
What are trim valves, and how do ball valves fit into this category?
Trim valves are auxiliary valves that support the operation, monitoring, and maintenance of fire protection systems. Ball valves are a common type of trim valve because they allow quick shutoff and easy control of water flow. They help with tasks like draining, replacing parts, and system testing.
Are ball valves suitable for high-pressure applications?
Yes, ball valves are designed to handle high-pressure environments depending on their construction and materials. Many industrial and fire protection ball valves are built to withstand demanding conditions while maintaining reliable shutoff. Their robust design makes them a common choice for high-pressure systems, with common max pressures of 300 PSI or 600 PSI.
How do ball valves help with system maintenance?
Ball valves make maintenance easier by allowing sections of a system to be isolated without shutting down the entire operation. They enable technicians to drain water, test pressure, or replace components safely. This improves efficiency and reduces downtime in fire protection systems.
What are the advantages of ball valves over other valve types?
Ball valves offer quick operation, tight sealing, and long-term durability compared to many other valve types. They are especially valued for their ability to provide immediate shut-off. While they are not ideal for fine flow adjustment, they excel in on/off control applications.
