brass Straight Ball Valve

Product Description

The Brass Straight Ball Valve is a fundamental component in modern fluid control systems, engineered to provide reliable "on-off" or "throttling" capabilities across a wide range of industrial, commercial, and residential applications. Characterized by its robust construction and high-performance design, this valve is a staple in plumbing, HVAC, and industrial processing.

Design and Construction

At the heart of the valve is a precision-machined, chrome-plated brass ball with a bore through its center. When the valve handle is in the open position, the bore aligns with the pipe's flow path, allowing for a straight-through flow with minimal pressure drop. A 90-degree turn of the lever rotates the ball, positioning the solid face against the flow to create a bubble-tight seal.

The body is typically forged from high-quality brass (such as CW617N or C37700), ensuring excellent mechanical strength and resistance to dezincification. To guarantee longevity and leak-proof performance, the internal ball is cushioned by PTFE (Teflon) seats, which provide a low-friction surface and a superior seal even after thousands of cycles.

Technical Specifications and Features

• Full Port Design: Most straight ball valves feature a full-port (full-bore) design, meaning the internal diameter of the valve matches the pipe diameter, ensuring maximum flow capacity.

• Pressure and Temperature: Designed to withstand high-pressure environments (often rated up to 600 PSI WOG) and a broad temperature spectrum, typically ranging from -20C to 150C.

• Blow-out Proof Stem: The stem is inserted from the inside to prevent it from being displaced by line pressure, enhancing operator safety.

• Versatile End Connections: Available with female-to-female (F/F), male-to-female (M/F), or compression ends to suit various installation requirements.

Primary Applications

Due to its corrosion resistance and durability, the brass straight ball valve is ideal for managing water, oil, gas (WOG), and compressed air. It is frequently utilized in municipal water systems, chemical processing lines, and fuel gas distribution, where quick shut-off and reliable sealing are paramount for system safety and efficiency.
