The valve has many components that you can choose from when ordering, thus it is always important to know the media or application the valve will be used in. Knowing what end connections you need is very crucial. Not all applications can accommodate.
- Raised Face (Flanged) Connections
- Ring Type Joint (Flanged) Connections
- Threaded Ends
- Socket Weld Ends
- Occasionally Butt Weld (Not Standard Production End Connection)
Fact: Did you know that Flanged End Connections are known for being easy to apply to your project?
You may wonder what the difference is between Flanged and Threaded Ends. Flanged Valves feature more bolts, resulting in less tightening, in contrast to Threaded End Connections which need more tightening. Flanged Ends overall can be used for any type of Valve, i.e. Gate, Globe, Ball, or Check. When you have a Threaded End, ultimately you will be working with a Low Pressure type situation. GVC offers Valves with Threaded End connections and can be modified to Socket Weld or Socket Weld x Threaded if need be.
Socket Weld End Connections are commonly used on Stainless Steel or Carbon Steel Valves. When you have a higher temperature and pressure rating you would want to turn to the SW Connection. GVC offers SW Ends and features their leak free seal.
Last but not least, the RTJ and Butt Weld End Connections: GVC stocks majority RTJ End Valves opposed to Butt Weld End Valves. Butt weld end valves are applied to most applications where a higher grade of steel, temperature and pressure is needed. An Engineer from an article I found states, “RTJ Valves have grooves cut into their faces in which they obtain steel Ring Gaskets. They seal when tightened bolts compress the gasket between the Flanges into the grooves, deforming the gasket to make contact inside the grooves, thus creating a metal to metal seal.” Each valve end is beveled to match with the thickness and bevel on the pipe.
Can you guess what the end connections in the picture are?
