Help, as the title says! ! ! ! ! ! ! ! 1
Slightly open flanged safety valve, flange face sealing, pressure rating 150lb, inlet DN50
It is estimated that a floating ball valve made of ammonia-resistant material will be used, with the sealing surface made of 316 stainless steel; the flange type is RF with a raised surface
Which fancy valve manufacturer came up with this model? This model isn’t accurate at all – a nominal pressure in US standards is added to what should be a standard Chinese standard model. I don’t think it’s a safety valve; AQ41R – the number 4 before it indicates the valve model. In cases of special requirements, letters can be added in front of the valve model for identification; for example, DQ41R refers to a low-temperature ball valve. Has this valve manufacturer come up with another type designation? The letter A stands for standards such as API and ASME; this type refers to a ball valve that complies with American standards, featuring an RF connection, a pressure rating of 150LB, a diameter of 2 inches, a 316 stainless steel sealing surface, and a valve body made of carbon steel. The use of a 316 sealing surface may be due to the requirement for resistance to hydrogen sulfide.
