Brass No-Loss Valve

Industrial Brass No-Loss Safety Valve

Maintain complete system integrity during routine maintenance and diagnostics with our Brass No-Loss Valve. Specifically engineered for pressure testing applications, this valve acts as an intelligent manual isolation gate. Its internal sealing mechanism ensures that when pressure gauges, test point probes, or transducers are screwed into or removed from the valve, zero system media escapes into the environment.

Featuring a ⅜” BSP Female internal thread for your instrument and a robust ½” BSPT Tapered Male thread for your pipeline or manifold entry, this valve is essential for high-pressure, hazardous, or costly fluid and gas lines. It not only prevents dangerous system pressure drops during gauge changes but also shields the technician from accidental contact with hot or pressurised media.

Key Features & Benefits

• Zero-Leakage Operation: Eliminates the “blow-back” of liquids or gases during gauge installation and removal, ensuring a safer workspace and zero loss of line pressure.
• Tapered Pipeline Connection: Outfitted with a standard ½” BSPT (tapered) male thread to provide a secure, high-pressure, interference-fit seal directly into the process line.
• Standard Instrument Port: Features a precision-cut ⅜” BSP parallel female thread, making it universally compatible with standard industrial pressure gauges and test points.
• Heavy-Duty Solid Brass: Machined from premium-grade brass for superior structural strength, resistance to mechanical wear, and excellent corrosion resistance in HVAC, pneumatic, and water systems.
• Hexagonal Wrenching Body: Designed with a clean hexagonal profile to ensure an easy, high-torque grip with standard spanners during installation.
