The Instrumentation Products Division Europe of Parker Hannifin has announced the addition of a tyre-actuated pneumatic valve to its Bestobell cryogenic globe valve range. The valve can be operated remotely with a single switch command, providing much greater speed and convenience than a manually operated type.
The tyre- actuated pneumatic valve complements the Parker Bestobell range of cryogenic valves, which covers gate valves, ball valves, check valves, and relief valves as well as globe types. It comes with all the same features, specifications, and certifications as the manually operated valves, and is available in the following valve sizes: DN25, DN40, and DN65. It also has various end connections, including butt weld, socket weld, and flanged.
Globe valves are used for pressure and flow regulation as well as shut-off. The tyre-actuated globe valve is particularly beneficial to cryogenic transport trailers, as its rubber actuator weighs significantly less than stainless-steel linear actuators. The valve features a longer, stronger spring to assure a robust seal on closure – an essential safety consideration. Remote control allows emergency operation; the valve can also be integrated into an automated system, or installed in inaccessible locations. Manual override is provided to perform an emergency discharge if air pressure is lost.
