What is a Valve Actuator?

Shafer®'s principal product is a valve actuator, which is mounted on the stem of a pipeline valve. Valve actuators are devices which permit the valve to be opened or closed automatically by either an internal self-generated signal or a remote, hydraulic, electric or pneumatic signal. Valve actuators are used on the piping of compressors, metering and regulating stations, distribution systems or transmission lines, refineries and petrochemical, gasoline and power plants and for certain marine applications.

Shafer® valve actuators are used primarily in the gas transmission pipeline industry, where reliability is critical. Hence, Shafer® has become recognized as "guardians of the world's pipelines." We have valve actuators in service in Siberia, the Andes Mountains, the floor of the ocean off the coast of Spain, and on long lines like the TransCanada pipeline. All of the valves on this 2,000-mile length of pipeline could be operated from a single location!

Markets Served

Shafer® Valve Operating Systems are sold worldwide for a vast number of applications, with export business accounting for 42% of the company's sales since 1980.

Oil & Natural Gas: Shafer® valve control applications begin with oil field and gas wells then continue through the pipeline transmission and distribution networks and refineries. Shafer® is especially recognized for critical applications such as emergency shutdown and linebreak protection. Shafer® also pioneered valve control products capable of withstanding the demands offshore platforms and subsea pipelines, along with a variety of specific marine applications.

Process Industries: Shafer® has developed valve actuators specifically to meet the requirements of the process industries such as pulp & paper, chemical, food & beverage, water & waste water, power and mining. Our products are often specified in the highly demanding valve control and priority shut-off applications in these industries.

R&D, Engineering, Manufacturing

Research and development represents our investment in the future. Many of our new products and the refinement of existing products are based upon concepts generated by our customers. Listening to customer concerns, and responding with engineered product solutions means Shafer®'s development and improvement objectives are always "market-driven." Because product quality and reliability begin at the drawing board, Shafer® products are continuously evaluated to ensure that the most current technology and materials are applied, using the latest computer aided tools.

Shafer's manufacturing facility and headquarters are located in Mansfield, Ohio, USA. The company manufactures virtually all of the metal components needed in its valve actuators from raw steel stock, which affords Shafer® the opportunity to control technology, craftsmanship and quality. Because our products require exacting tolerances and zero defect components, every phase of production uses state-of-the-art equipment and highly-trained personnel. Shafer® was certified under the ISO 9001 quality standard in March of 1993. This certification is not only important to export sales, it serves to solidify Shafer®'s market reputation for excellence.
