Valve Repair Services

Valve repair services repair and rebuild used valves. They may perform blast cleaning and degreasing operations, apply corrosion-resistant and anti-wear coatings, and provide non-destructive evaluation (NDE) test and inspection. Valve repair services may also produce full-dimensional inspections and reports, and specialize in reverse engineering and parts remanufacturing. Valve repair services which perform metal inert gas (MIG) welding, tungsten inert gas (TIG) welding, and other valve welding operations are also available. Related repair techniques include plasma cutting, machine tooling and fixturing, and field laser alignment.

Valve repair services specialize in the repair and rebuild of many different types of used valves. Examples include angle valves, back flow prevention valves, balancing valves, ball valves, bellows valves, block-and-bleed valves, blow-off valves, butterfly valves, cartridge valves or manifold valves, check valves, clamshell valves or bin gate valves, and control diaphragm valves. In addition, valve repair services may specialize in the repair and rebuild of directional valves, diverter valves, double-flap airlock valves, drain valves, duckbill valves, float valves, foot valves, and gate valves or knife valves.

Some valve repair services repair and rebuild globe valves, hydraulic valves, iris valves, metering valves, mixing valves, needle valves, pilot valves, pinch valves, plug valves, pneumatic valves, poppet valves, and pressure relief valves. Other valve repair services repair and rebuild shut-off valves, sampling valves or dispensing valves, safety valves, sanitary valves or hygienic valves, servo valves, solenoid valves, spool valves, toggle valves, underwater valves, and vacuum relief valves or anti-siphon valves. Valve repair services that work with specialized, proprietary or patented products are also available.

Valve repair services are located across North America and around the world. They comply with both voluntary standards and regulatory requirements for valve repairs. The International Standards Organization (ISO), a worldwide federation of national standards bodies, establishes voluntary guidelines. The American National Standards Institute (ANSI) represents the United States in ISO. Industry-specific standards for valve repair services include QS-9000 and AS9100. QS-9000 is a quality standard for suppliers of DaimlerChrylser Corporation, Ford Motor Company, and General Motors Corporation. AS9100, a standard from the International Aerospace Quality Group (IAQG), contains over 70 requirements specifically for aerospace and aviation companies. Regulatory agencies such as the U.S. Food and Drug Administration (FDA) also provide guidelines that valve repair services need to follow.
