Does anyone know the application of double block and bleed valve, i understand this valve consists of double seats with a body bleed, is it correct? Aslo, i heard that in case the pressure rating 900 and above, the double block valve (Two valves seried with a bleed) shall be applied. Double Block and Bleed valve shall not be considered for this application.
For this, do they have any code or standard concerned this matter. Your help will be very appreciated.
