Key benefits

· High flow coefficient
· High accuracy, even at high flow rates
· Reduced lock-up pressure zone and lock-up pressure
· Reduced response time, no internal leakage at zero flow rate
· Fail to open
· Periodic maintenance without disassembling the valve from the pipework
· Ability to retrofit the SD100 or SD400 slam-shut OPSO/UPSO, without modifying the existing piping
