    Do you have a time for the valve to go from full open to full closed ?
  1. Q Do you have a time for the valve to go from full open to full closed ?
    A The time to go from fully-closed to fully-open on these actuated butterfly valves is 1.5 seconds.
  2. Is this valve air operated?
  3. Q Is this valve air operated?
    A Yes, this tri-clamp actuated butterfly valve is an air actuator. Since the valve setting is Normally Closed (NC), air is required to open the valve and a spring is used to close once air pressure is relieved.
