A104-DL Low Leakage Bellows Seal Cage Type Control Valve

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

• 
  • Various valve body materials for, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials

• 
  • 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

• 
  • 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

• 
  • Bellows seal structure adopted for the upper bonnet, eliminating the possibility of medium leakage from the valve stem movement clearance
