Jamesbury ball valves are reliable and long-lasting valves. Their cycle life of can be as much as 100 times longer than with competitive products.
By focusing on the all-important areas of seat design, polymer material research, and sealing technologies – Jamesbury™ was able to engineer and deliver next-generation ball valve performance. Solutions that offer vastly improved stem sealing and cycle life.
FM-Approved Emergency Shut-Off Heat Activated Valves (FM Figure 1075) These valves provide emergency shut-off for flammable gases, liquids and toxic fluids where ambient temperatures exceed acceptable limits. FM-approved and available with fusible links for 165° F (73° C) to 200° F (93° C) shut-off.
One look – both inside and out – and you can see that next generation Jamesbury® valves are much more than your average valve. You’ll notice a streamlined common version theme that integrates five valves that make them look totally different than past models.
The JAMESBURY® polymeric-seated flanged ball valves offer a patented flexible-lip seat design that pro-vides positive bi-directional shut-off for a variety of appli-cations in industries ranging from chemical and petro-chemical to refining, pulp and paper, and power.
We believe that our Jamesbury valve and actuator solutions provide the best performance available on the market today. How can we make such a bold statement? It’s our technology. Innovative sealing designs that eliminate leaks. Seat materials that withstand extraordinary extremes in temperature and pressure.
The superior performance of Jamesbury ball valves is achieved by the unique design of the seats. The flexible lip seats exert continuous sealing pressure on the ball and automatically compensate for wear and changes in pressure and temperature, yielding positive bi-directional zero-leak shut-of.
