Profile: R. E. Mason Co. is a supplier of Fisher valves and regulators. We offer a large array of process automation and asset management solutions. We provide solutions that include process control valves, regulators, automated on-off valves and instruments for demanding industrial applications. We provide a wide complement of valve and instrument services, including complete engineering, assembly, staging, calibration, loop checkout & commissioning, bus design & configuration, and outage management. We offer reliable control valves, regulators, instrumentation and performance services to the process control industries. Our manual handwheel actuators are used in applications that require a throttling type of control valve that can be manually operated and set. Capable of giving precise manual throttling control, these actuators can be used on nearly all standard globe-style or angle-style valve body assemblies. A travel indicator on the actuator yoke can provide a visual indication of valve plug position. The Fisher 1008 manual handwheel actuator is used in applications that require a throttling type of control valve that can be manually operated and set. A pneumatic actuator provides high stem force output for demanding service conditions. These actuators are usually air operated but some can be self operated by the process fluid. Fisher spring and diaphragm pneumatic actuators can be direct-acting, meaning that air to the diaphragm casing pushes the actuator stem downward.
