pressure, eliminating hunting by the control system, even at low coil flow. The pressure regulator virtually eliminates cavitation in the valve, and decouples the control valve from the effects of piping components such as reducers and elbows. Pressure independent control valves are sized to match design coil flow regardless of coil size. API - Valve StandardsValve standards from API - the American Petroleum Institute:. API SPEC 6D Specification for Pipeline Valves. API Specification 6D is an adoption of ISO 14313:1999, Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball

Ball Valve - an overview ScienceDirect Topics

Seals are usually resilient and can provide drop tight shut off. Ball valves are commonly used in small diameters (up to DN 300) although at least one manufacturer can make ball valves up to DN 1200. Ball valves are manufactured in one-piece, top entry, two-piece (Fig. 18.6) and three-piece bodies. A top entry body allows access to the ball and seats for maintenance without the need to remove the valve Control Valve Basics:Sizing and Selection MSS SP-69 for general butterfly valves UL 1091 for safety butterfly valves for fire protection services Advantages: Low cost and maintenance High capacity Good flow control Low pressure drop Disadvantages: High torque required for control Prone to cavitation at lower flows

pressure analysis with a mass spectrometer or the time-related pressure rise test may be used. Since it is only possible to determine the existence of a leak and not its position in the system when using the pressure rise test, it is recommended to use a helium leak detector with which the leaks may also be localized significantly faster. Fundamentals of medium voltage switchgear EatonMetal-clad switchgear is defined by IEEE C37.20.2 and refers to the construction of medium-voltage electrical switchgear where all electrical components including the incoming bus, outgoing bus, instrumentation and main circuit breaker or switch, are enclosed in separate metal compartments to provide an additional level of safety, ruggedness and ease of maintenance.

  • What Is It?Terms UsedThe DirectiveThe (PED) European Pressure Equipment Directive (European Commission Directive no. 97/23/EC) is similar to the ASME Boiler and Pressure Vessel Code in that it provides requirements for certain pressure equipment. However, there is one major difference between the ASME Code and the PED; as a directive, or European law, PED compliance is mandatory within the European Union (EU) and for components being sent to the EU, for work on pressure-retaining equipment as defined under that law. The PressurLeading the way in pressure relief technologyHigh flow safety relief valves for gas, steam, liquid and mixed-phase applications.
