Brass Globe Valve (Red Hollow - out Handwheel, Female Thread)
Good Shut-Off Capability: When fully closed, it offers a tight seal with minimal leakage.
Durability and Corrosion Resistance: Brass construction offers excellent resistance to corrosion from water and many chemicals, ensuring a long service life.
Ease of Maintenance & Repair: The seat and disc are often easily accessible and replaceable without removing the entire valve from the pipeline, especially in union bonnet designs.
Robust and Reliable: Simple mechanical design with strong materials makes it a trusted component in critical systems.
Cost-Effective: For its range of functions, brass globe valves are generally affordable and widely available.
Features are the physical design characteristics that enable its function.
Spherical Body: The distinctive shape that creates a complex flow path.
Linear Motion Stem: The stem moves up and down rather than rotating, connected to a handwheel via threads.
Disc and Seat Design: The heart of the valve. The disc can be a flat, conical, or ball shape that mates precisely with the seat to form a tight seal.
High Pressure Drop: The internal"S-shaped"flow path (Z-body) causes a significant change in flow direction and pressure loss, which is a trade-off for its regulating ability.
Bonnets: The top section that houses the stem. It can be:
Screwed Bonnet: Simple and common for low-pressure applications.
Union Bonnet: Allows for easy maintenance and is more robust.
Bolted Bonnet: For higher-pressure applications.
Packing Gland: A system (often graphite or PTFE) that seals the stem where it exits the bonnet, preventing leaks.
