A Flow control valves may be installed between the safety valve and the system that is being protected so long as they are practically almost always open References: 1 The Pressure Equipment (Safety) Regulations 2016 (UK Statutory Instrument 2016 No.1105). 2 The Simple Pressure Vessels (Safety) Regulations 2016 (UK Statutory Instrument 2016 No.1092). 3 Withdrawn Superseded UK standard BS 6759-1 1984 Safety valves. Specification for safety valves for steam and water. 4 NABIC recommendation direct communication. 5 Approved Code of Practice and guidance L122 Safety of pressure systems, UK HSE 2014. B If valves are mounted in other than a vertical position, the valve manufacturers recommendations must be considered C Safety valves may be manually isolated from the equipment that is being protected if an appropriate alternative safety device is connected D Devices such as manual three-way valves can provide connections to alternative safety devices when a safety valve is under maintenance E When testing, alternative safety device(s) connected to the equipment must provide the required full relief capacity 68 October 2020 www.cibsejournal.com CIBSE Oct20 pp65-68 CPD168 NABIC v2.indd 68 25/09/2020 17:13
