Product details
Weiss Gauge Cock | BTC12 | 1/2″ NPT | Brass | T-Handle
Product Description
The BTC12 is a primary isolation accessory for mechanical plant rooms where space is at a premium. The “BTC” designation identifies this as a Brass T-Handle Cock, and the “12” denotes the 1/2″ NPT connection size.
In the UAE’s industrial sector, 1/2″ NPT is the preferred connection for main process headers and large-dial gauges (4.5″ and 6″). The T-handle design is particularly advantageous in dense piping layouts—such as those found in chiller plants or pump rooms in Dubai and Abu Dhabi—where a standard lever handle would strike adjacent pipes or walls. The internal plug mechanism allows for a simple on/off operation, enabling maintenance teams to safely swap or calibrate gauges without interrupting system flow.
Key Features
- Compact T-Handle Operation: Eliminates the “swing” radius required by lever handles, making it ideal for tight mechanical spaces and manifold mountings.
- Heavy-Duty Brass Construction: Provides excellent durability and resistance to corrosion in freshwater, chilled water, and compressed air systems.
- 1/2″ NPT Industrial Connection: A robust Female-to-Female thread size that ensures a secure mechanical mount for heavy industrial instruments.
- Simple & Reliable Design: Features a minimal number of moving parts, ensuring long-term reliability and leak-free performance in building service applications.
- Economic Isolation: Offers a cost-effective alternative to needle valves for systems operating within standard pressure ranges.

Frequently Asked Questions
- Q: Why use the BTC12 (T-Handle) instead of the BLC12 (Lever Handle)?
- A: Functionally they are the same, but the T-handle (BTC12) is much better for tight spots. If your gauge is located near a corner or surrounded by other valves, the T-handle is easier to turn without obstruction.
- Q: Is this suitable for high-pressure water booster systems?
- A: This valve is rated for 200 PSI. If your system pressure exceeds this (common in high-rise towers), a 1/2″ Needle Valve (50NVBR) should be used for safety and better control.
- Q: Can this be used for steam service?
- A: It is rated for temperatures up to 200°F, which is suitable for low-pressure steam heating. For high-pressure industrial steam, a dedicated steam-rated valve and a syphon are required.
