Specification of damping ball valve pneumatic butterfly valve PTM-D series pneumatic butterfly valve is composed of nodular cast iron shell, horizontal adjusting bolt, valve gasket, bottom plate with anti-skid valve gasket and reserved limit hole
The application of TPTM-D series pneumatic butterfly valves is typically to reduce the transmission of noise and vibration from fluid equipment such as boilers, cooling towers, etc. to the structure, while taking into account the load
When under rated load, the outer diameter of the ball valve is greater than 80% of the height of the ball valve after load
The load of all ball valves exceeds 50% of the rated load listed in the table, making the coefficient of pneumatic butterfly valve higher
Installation instructions for pneumatic butterfly valve of damping ball valve 1. Check and adjust the locating bolt at the lower part of the bearing plate
2. Adjust the flat bolt&nut to leave a 2-3mm gap between the pad and the bracket
Adjust the level again after the equipment is filled with water; Adjust the pneumatic butterfly valve until the bearing plate contacts the bottom of the equipment and inserts the screw through the bottom of the equipment and the support
