Bidirectional Brass Gate Valve — DN15 to DN50 | Internal Thread Water Shutoff
Take precise control of your water flow with this heavy-duty Bidirectional Brass Gate Valve. Available in a full range of sizes from 1/2" (DN15) to 2" (DN50), this manual shutoff valve is built from high-quality copper brass for exceptional durability, corrosion resistance, and long-lasting performance in both residential and commercial plumbing systems.
Featuring a female internal threaded connection, this gate valve installs easily into standard pipe fittings and operates bidirectionally — meaning it handles water flow in either direction without sacrificing seal integrity. The sturdy manual handwheel provides smooth, reliable open/close operation every time.

- Working Pressure: Up to 850 kPa (approx. 123 PSI)
- Operation: Manual handwheel — simple quarter-to-full turn control
- Application: Water supply lines, irrigation systems, boilers, heating circuits, and industrial pipelines
Why Choose a Brass Gate Valve?
Brass gate valves are the industry standard for water shutoff applications due to their excellent sealing capability, minimal flow restriction when fully open, and outstanding longevity. Unlike ball valves used for quick shutoffs, gate valves allow for fine-tuned flow regulation and are ideal for systems where the valve remains in a predominantly open or fully closed position.
Whether you're installing new plumbing, upgrading an irrigation system, or replacing a worn valve in a commercial setting, this bidirectional brass gate valve delivers professional-grade reliability.

Frequently Asked Questions
Q: What pipe sizes does this brass gate valve fit?
A: This bidirectional brass gate valve is available in six sizes: 1/2" (DN15), 3/4" (DN20), 1" (DN25), 1-1/4" (DN32), 1-1/2" (DN40), and 2" (DN50). Please select the size that matches your existing pipe diameter when ordering.
Q: Is this gate valve suitable for both hot and cold water systems?
A: Yes. The high-grade brass construction makes this valve suitable for use in both hot and cold water supply lines, heating systems, and irrigation applications, provided the working pressure remains below 850 kPa (approximately 123 PSI).
Q: Does the valve need to be installed in a specific flow direction?
A: No — this is a fully bidirectional gate valve, meaning it operates correctly regardless of which direction water flows through it. This makes installation straightforward and flexible.
Q: What thread standard does this valve use?
A: This valve features a female internal thread connection, compatible with standard BSP (British Standard Pipe) and NPT (National Pipe Thread) fittings commonly used in residential and commercial plumbing.
