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
· Optional shut-off valve
· Internal sense and easy connected
