The Lightweight Stainless Steel 2-Piece Thread Ball Valve is a compact, easy-to-install solution for on/off flow control in low-to-medium pressure systems. Constructed from 304 stainless steel, this valve features NPT threads (ANSI B1.20.1) and a lightweight design, making it ideal for commercial plumbing, HVAC, and light industrial applications where space and weight are critical.
Compact & Lightweight Design:
30% lighter than equivalent cast iron valves (e.g., 0.5kg for 1" size), reducing strain on overhead pipelines and portable equipment.
Two-piece body with union connection for easy maintenance, allowing stem and seat replacement without disconnecting the pipeline.
Reliable Sealing Performance:
PTFE seat provides bubble-tight shutoff (API 598) up to 100 PSI, with a polished ball (Ra ≤0.8μm) ensuring low operating torque (≤8 N·m for 1" valves).
Blowout-proof stem design and anti-static spring (dissipates static charge in gas applications) enhance safety compliance.
Threaded Connection Advantages:
NPT male/female threads for quick assembly/disassembly, compatible with steel, copper, and PEX pipes, eliminating the need for welding or press tools.
Thread sealant not required for water applications; optional PTFE tape recommended for gas systems to enhance leak resistance.
Operational Flexibility:
Temperature range: -20°C to 180°C (PTFE seat), suitable for hot water, compressed air, and non-corrosive liquid lines.
Available in full-port (100% flow efficiency) and reduced-port (space-saving) options, with sizes ranging from 1/4" to 2" NPS.
Perfect for commercial and light industrial settings:
Plumbing & Residential: Water supply lines, shutoff valves for sinks/faucets, and radiant floor heating systems, compliant with NSF/ANSI 61 for potable water.
HVAC Systems: Control valves for air conditioning condensate lines and small refrigerant pipes in rooftop units and data centers.
Food Service: Beverage dispensing systems and ice machine connections, with 304 stainless steel meeting FDA requirements for indirect food contact.
Laboratory Equipment: On/off control for non-corrosive reagent lines and vacuum systems, with reduced-port models suitable for low-flow applications.
Q: Can this valve be used with steam?
A: Limited to 150°C (PTFE seat); for higher temperatures, choose a valve with an RPTFE seat (up to 260°C).
Q: What is the difference between full-port and reduced-port models?
A: Full-port valves have the same bore as the pipe (e.g., 1" bore for 1" valve), while reduced-port valves have a 20% smaller bore for compactness.
Q: How to lubricate the stem for smooth operation?
A: Apply a food-grade lubricant (e.g., silicone grease) to the stem packing every 6-12 months, depending on usage frequency.
Q: Is the valve suitable for buried installations?
A: Yes, but use a valve box for access and protect threads with anti-corrosion tape to prevent soil moisture damage.
