What is BS 4062-2 - Valves for hydraulic fluid power systems about?
BS 4062-2 is an international standard that specifies methods for testing hydraulic valves which are used for the control of flow or pressure in a circuit in order to determine their steady-state and dynamic performance. Requirements for test installations and procedures, measurements, and presentation of results are specified.
BS 4062-2 does not establish limits of performance since the suitability of the valve for its intended purpose should be agreed upon between the manufacturer and the user. Accuracy of measurement is divided into three classes (A, B, and C) which are explained in Annex A. Guidance as to the use of practical units for the presentation of results is given in Annex B. Proportional control valves are not dealt with in BS 4062-2.
Who is BS 4062-2 - Valves for hydraulic fluid power systems for?
BS 4062-2 on valves for hydraulic fluid power systems is useful for:
- The hydraulic industry
- Testing agencies
- Valves manufacturers
- Quality control personnel
- The chemical industry
- The power plant industry
- The mining industry
Why should you use BS 4062-2 - Valves for hydraulic fluid power systems?
In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. Hydraulic valves may be used to control the direction, pressure, or flow rate of the working fluid by adjusting or controlling their resistance to flow. ISO 4411, in which methods for determining the steady-state differential pressure/flow characteristics of hydraulic valves are specified, forms part of the same series of International Standards. The test requirements for production purposes may differ from those specified in BS 4062-2.
BS 4062-2 provides its users with general requirements for installation procedures and instructions for test procedures for the quality assurance of the valves for hydraulic fluid power systems. Using BS 4062-2 guidelines ensures high quality and better performance for a longer service life.
