Diaphragm valve A104-DL

pneumaticalloystainless steel

It is widely adopted in the automatic control system of highly toxic, highly corrosive, radioactive and rare precious media. Features Multi-spring pneumatic diaphragm actuator or cylinder-type double-acting actuator available for, simple and firm structure, large output force and long service life Compact structure and S-shaped streamlined channel of valve body, enabling small pressure drop loss, large flow, wide adjustable range, high accuracy of flow characteristics Bellows seal structure adopted for the upper bonnet, eliminating the possibility of medium leakage from the valve stem movement clearance Various valve body materials for, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials Pressure balance structure of valve element, using small actuator thrust to control the high pressure difference, and a sealing ring between the valve element and the valve cage to reduce leakage
