Rules and regulations, standards and specifications for instrument valves

Rules and regulations, standards and specifications for instrument valves

Valves are useful in wide variety of applications. Valves are used throughout the industrial, commercial and residential industries and the diverse uses demand that valves production meet stringent standard regulations for safety and other purposes. As a result, many regulatory Refer to This organizations are up and doing to ensure that valves function at their best, meet compatibility needs and guarantee safety for users.

Valves are critical materials used in fluid system control. They provide the gateway that decides what comes and goes regarding the flow of volume and pressure. A faulty valve will disrupt the free running of any flow control system, and a sudden breakdown may spell disaster in critical operations. Therefore, so much value is placed on the engineering, design, production, and sales of valves to ensure top quality valves are available to end users.

Engineers designing valves consider a global application in their design and production. To produce acceptable valves for global use, it must be produced according to globally certified standards. To ensure strict compliance with efficient production of valves, manufacturers are expected to meet these delicately designed standards and specifications. Also, at government levels, regulatory authorities are in place to regulate standards and enforce compliance. Furthermore, players in the flow control industry have also deemed it fit to come together to establish trade organizations that will serve as a watchdog to ensure that every valve produced meet lay down standards and specifications. Essentially, different bodies are established to monitor and enforce compliance with an established specification for valve instrumentation.

Engineers designing valves must take cognizance of the main functions of the instrument. It is with these functions in mind that the right policy, standard, and specification will be applied.  Valves perform four major functions as listed below:

  • Regulation – It performs control and adjustment function by regulating the flow rate of fluid content in a flow control system.
  • Direction – Manage the flow path of media with many circuits.
  • Protection – It provides check and relief function to protect system pressures or filtration.
  • Isolation – it provides on or off function to connect to or isolate the flow system.

 To ensure reliable and top quality valves, rules, and regulations are provided to check the activities of stakeholders in the flow control industry. As a result, major standard organizations exist to monitor activities of players in the industry. The following are some of the standard organizations established to provide rules and regulations to guide the industry. These organizations also come up with standards and specifications for valve engineers and manufacturers to comply within the industry.

  • American Petroleum Institute (API).
  • American Society of Mechanical Engineers (ASME).
  • American National Standards Institute (ANSI).
  • ASTM International (FKA American Society for Testing Materials).
  • Manufacturers Standardization Society (MSS).

 Additionally, valve design engineers have specific industrial standards to follow, below are relevant valve standard to include in their designs.

  • API Valve Standards
  • ASHRAE Valve Standards
  • ASME BPVC Valve Standards
  • ASSE Valve Standards
  • AWWA Valve Standards
  • ISA Valve Standards
  • NFPA Valve Standards
  • SAE Valve Standards

Rules and regulations, standards and specifications for instrument valves

To have reliable and top quality valves in the flow control industry, every stakeholder must play an active role in ensuring due diligence is followed. From the importance of abiding by the rules and regulation in the industry cannot be overemphasized due to needing to ensure that people and material resources are well protected from disaster due to valve failure.
