• The valve adopts swing type structure, casting body adopts streamline body design, the valve flow resistance is small;
• Body sealing face tilt 30°, reduce check valve closing time, ensure fast closing;
• The valve disc of the closing part is connected with the valve stem by rocker, and the valve disc is rotated around the valve stem, which can make the valve disc fall on the valve body sealing surface accurately and ensure the anastomosing of the sealing surface;
• A heavy hammer can be designed to balance the heavy torque of the disc assembly when the valve diameter is large. When the medium is flowing forward, it helps to open the check valve and keep the check valve stable during operation, reducing vibration;
• The side-mounted actuator is spring return single acting straight stroke pneumatic device or hydraulic device. The gas/hydraulic unit is installed on the left side by default (looking in the direction of airflow), if the user has special requirements, it should be indicated in the contract, and the gas/hydraulic unit can be installed on the right side.
