Screwed Gate Valves
When it comes to small-scale commercial, residential, or light industrial piping, screwed gate valves are the industry benchmark for dependable fluid isolation.
Engineered with female internal threads on both ends, these valves screw directly onto male pipe threads to create a tight mechanical seal.
Because they provide a completely clear pathway when fully open, they offer maximum flow capacity with practically zero pressure loss, making them a staple in low-to-medium pressure installations.
Key Advantages of Screwed Connections
- Cost-Effective Construction: Screwed gate valves are generally lighter, more compact, and significantly less expensive than their flanged counterparts.
- Tool-Free Welding: They require no specialized welding equipment, torches, or heavy machinery to install. A standard pipe wrench and pipe sealant or Teflon tape are all it takes.
- Compact Footprint: Because they do not feature large, protruding outer flanges, they fit seamlessly into highly confined spaces and tight utility closets.
Common Applications
Screwed gate valves are predominantly manufactured in smaller sizes (typically 1/2" up to 2" or 3") using robust materials like brass, bronze, and stainless steel. You will routinely find them in:
- Domestic and commercial plumbing lines
- Compressed air and gas distribution networks
- Light industrial HVAC systems
Main water shut-offs for individual equipment lines
