Q & A

Jamesbury™ Series 5H Standard Port Ball Valve Q & A

+ What size options are available for the Series 5H valve?
The Series 5H is available in threaded (screwed-end) sizes from ¼″ to 2″ (DN 8 to 50).
+ What materials are used in its construction?
The valve body is available in carbon steel or stainless steel. The internals often include a stainless ball (e.g. 316 SS), a 17-4PH stem, and seats made of acetal/PTFE combinations (depending on the variant) for tight sealing.
+ What sealing / seat technology does it use, and how tight is the shutoff?
It features a flexible-lip seat (Double-Seal™ design) that provides long-lasting bubble-tight shutoff in either flow direction. The leakage performance exceeds ANSI/FCI 70-2 Class VI.
+ Is the valve bi-directional?
Yes. The Series 5H is designed for bi-directional flow and sealing, making it suitable even in applications where flow direction may vary.
+ Can it be automated / actuated?

Yes. The design supports actuator mounting. The linkage allows actuators to be attached without disassembling the valve body. The valve/actuator linkage can handle loads up to about 200 lb (91 kg) without misalignment issues.
