Product Description

Parallel safety return valve: The parallel safety return valve is installed on the liquid phase return pipeline at the outlet of the tank pump of the liquefied petroleum gas station. When the front pressure of the pump exceeds the specified value, the valve automatically opens and plays a safe return role to ensure the safe operation of the equipment and pipelines.

Safety valve main points of order

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.
