Today, Cameron’s THORNHILL CRAVER adjustable and positive choke valves are commonly employed for production manifolds, wellheads, heaters, critical services, well testing and well cleanup. The force- balanced design concept distributes the force of downstream pressure to the stem and thus reduces the effects of upstream pressure almost entirely. This, coupled with the upper stem design that rotates in a bearing independently of the lower stem, reduces the torque needed to operate the valve. This makes the valve easier to operate overall than conventional types of chokes and eliminates the need for potentially costly gear operators. Engineered for heavy-duty, maintenance-free performance and backed by Cameron’s dedication to quality, the THORNHILL CRAVER brand is just another example of Cameron’s valve expertise.
