A Complete Guide to Screwed Ball Valves
If you're in the business of sourcing valves, screwed ball valves are likely a staple in your procurement list. Compact, reliable, and versatile, these valves are perfect for controlling fluid flow in pipelines. Flowork’s range offers high-quality options designed to meet diverse industrial needs, ensuring durability and ease of operation.
What Are Screwed Ball Valves?
Definition and Basic Function
A screwed ball valve is a type of valve with threaded ends that connect directly to piping. Unlike flanged or welded valves, these are easy to install and remove, making them ideal for small to medium piping systems. The internal ball mechanism allows precise flow control and quick shutoff, which is crucial for minimizing downtime in your operations.
Key Points:
- Compact design, suitable for tight spaces
- Quick installation without welding
- Full or partial flow control capability
- Compatible with various piping materials
- Durable against high pressure and temperature
