BS EN IEC 60534-4 is the fourth part of the IEC 60534 series that specifies the requirements for the inspection and routine testing of control valves manufactured in conformity with the other parts of IEC 60534.
BS EN IEC 60534-4 is applicable to valves with pressure ratings not exceeding Class 2500. The requirements for actuators apply only to pneumatic actuators.
Note: BS EN IEC 60534-4 does not apply to the types of control valves where radioactive service, fire safety testing, or other hazardous service conditions are encountered. If a standard for hazardous service conflicts with the requirements of BS EN IEC 60534-4, the standard for hazardous service should take precedence.
BS EN IEC 60534-4 on industrial-process control valves is useful for:
By implementing a control valve diagnostics programme, plant personnel can have a better understanding of each control valve's genuine status, as well as predict exact maintenance requirements. Maintenance costs are significantly reduced. Increasing the overall efficiency of the plant.
BS EN IEC 60534-4 provides you with requirements for the conduction of tests and the procedures to be followed to assess the efficiency and performance. Using BS EN IEC 60534-4 guidelines you can enhance the safety and protection along with performance, quality assurance, cost-effectiveness, and durability of valves.
