STE5 To Operate Spring Loaded Safety Valves As Controlled Safety Pressure Relief Sytems Pneumatic Control Unit
High pressure safety valve for boiler protection with welding end or flanged connections
Features
• High tightness up to set pressure due to supplementary load
• Small opening and closing pressure differences
• High setting accuracy and reproducibility
• Opening possible even below set pressure
• Pressure setting of safety valve during normal plant operation
• Check of the control function without operation of the safety valve
• With one unit more than one safety valve can be operated
• In case of failure, the safety valve opens as direct spring valve (fail-safe function)
• No electrical energy supply necessary
• Ideally suitable for explosion Protection
GENERAL APPLICATION
The efficiency of plant operation can be increased by application of pneumatically assisted operation on a spring loaded safety valve. All control paths are three times redundant and the unit is working according to the fail safe principle. The advantages of direct acting safety valves will be combined with the advantages of controlled safety valves
Quality of compressed air: Filtered and dried; due point temperature at least 10 °C lower than ambient temperature
