Safety valve order main matters

Safety valve medium, pressure level, opening mode (full opening/micro opening) set the take-off pressure, determine the valve size, connection mode, standard maximum temperature resistance, release flow/hour, valve body material, internal valve body structure, working principle, installation instructions and other related technical data. Safety valve selection is mainly based on (take-off pressure and neat pressure flow temperature) caliber general design institute will be given, and in fact through the steam pressure, flow and take-off pressure, you can infer the size of the safety valve. Generally, it will be smaller than the caliber selected by the design institute. When the occasion is very important or the environment is more complex, please try your best to provide design drawings and detailed parameters, by our Xuan Cheng valve company experts for your review.
