Overview
The KITZ 125 brass gate valve is a Class 125 forged brass manual isolation valve with threaded connections and a non-rising stem design. Built to ASME B1.20.1 standards, this valve is rated for 200 WOG (working pressure at 100°F) and 125 WSP (saturated steam). The non-rising stem mechanism keeps the stem inside the valve body, preventing overhead interference in tight installations.
Key Features
- Non-Rising Stem: Stem remains inside the valve body for compact overhead clearance and safety.
- Full-Bore Design: Unobstructed flow path maximizes flow capacity and reduces pressure drop.
- Forged Brass Construction: Superior corrosion resistance and durability in diverse media including water, oil, and gas.
- Screwed Bonnet: Field-replaceable internal components for extended valve life.
- ASME B1.20.1 Threaded Ends: NPT or ISO connections for standard industrial installations.
- Class 125 Rating: Proven ANSI/ASME pressure class for general service applications.
