F650 Series Cast Steel Check Valve Size Range DN15～DN600 Temperature Range -25～450℃ Body Materials Carbon steel Bonnet material Carbon steel Disc material Carbon steel Stem material Stainless steel - Hard surface material seat, API internals Double Flange Check Valve Features and advantages Rugged construction ensures safety in the appropriate pressure temperature range. dual disc check valve Can provide flange and butt two connections. The bonnet does not require removal of the valve from the line, allowing access to the maintenance hinge and disc. The valve flap is closed by its own weight to prevent the backflow of the fluid to form a sufficiently large flow rate to avoid damaging impact. Through the balance valve and the "wing" structure, the head loss (or head loss) is reduced to the minimum extent. Shorter stroke, combined with the advantages of the balance valve, the valve closed more quickly, to minimize the impact of the phenomenon. Because of the small gap on the pivot pin, a funnel tight seat seal can be achieved throughout the pressure range to ensure the integrity of the valve seat seal between the disc ring and the valve body.

Composite Exhaust Valve China Air Release Valve supplier Features and advantages The exhaust process is smooth, can prevent the occurrence of pressure fluctuations or other destructive phenomena. Air can be discharged in the pipeline when the water is filled with water, and can be evacuated or negative pressure in the pipeline, such as the water column separation conditions will be automatically opened, into the pipeline to eliminate negative pressure. High speed exhaust gas flow, and even the high speed airflow mixed with water mist will not cause the exhaust port to be closed in advance. The vent is closed only after the air is completely discharged. At any time, as long as the system pressure is lower than atmospheric pressure, such as the occurrence of water column separation phenomenon, the air relief valve will immediately open the system into the air, to prevent the emergence of negative pressure in the system. At the same time, the system emptying time in a timely manner can accelerate the emptying rate.
