Hub End Ball Valves
Hub End Ball Valves, Hub end connectors are around 80% lighter than standard ASME B16. 5 flanges, and they use significantly less space. Reduce Downtime – They can be assembled or dismantled quickly with fewer bolts, thus helping to reduce the downtime. Grayloc Hub end is the is most popular type of hub end ball valves.

Key Specifications / Features
For hub end ball valves, the end connection must be machined accurately and good smooth finish. One of the customer turned to us for hub end ball valves and told us “We bought hub end ball valves from other valve manufacturer, however the valves were not able to connect to the clamp connector”.
Valve hub ends are to designed according to the dimension of Grayloc® clamp connectors or as customer specifications.
What is a Hub and Clamp Connector?
A hub and clamp connector is an alternate method to traditional ASME B16.5 pipe flanges of connecting pipe spool joints to each other or other equipment. This metal-to-metal sealed connector is reliable and easy-to-assemble.
Advantages of Using Hub & Clamp Connectors
Simple Connection – As compared to the conventional flanges, only four bolts are required to install.
Lighter & Smaller – Hub and clamp connectors are around 80% lighter than standard ASME B16.5 flanges, and they use significantly less space.
Reduce Downtime – They can be assembled or dismantled quickly with fewer bolts, thus helping to reduce the downtime.
Economical Solution – A hub and clamp connector is affordable and can help reduce the total cost of installation.
Leak-Free – It helps to withstand temperature and load variations and ensures leak-free operation when correctly installed.
Uses & Applications of Hub & Clamp Connectors
The hub and clamp joint is used in piping systems that require high integrity seals in applications involving erosive, corrosive, high pressure and temperature, and cyclic conditions. In addition to this, they are also used in compressors, manifolds, pumps, pipeline pig closures and valves. Some manufacturers are also certified to supply hub and clamp connectors for pressure vessel nozzles.
