A single-seat control valve with large Cv value, high rangeability, and accurate flow control performance.
- The flow path is designed for minimal pressure loss. The valve has a large Cv value, high rangeability, and accurate flow control performance.
- The plug is securely held in place by a top-guided stem with a long stroke, making it highly resistant to vibration.
- SIL3-capable: certified by the U.S. company exida

A wide range of available materials
Products can be provided to meet a variety of body material specifications, such as: carbon steel, which is generally used with water, steam, and fuel oil; highly corrosion resistant stainless steel, which is essential for controlling corrosive fluids; and resin.
Excellent seat leakage performance
Metal seat tight shutoff (class IV, V) and soft seat tight shutoff (class VI) are available.
Excellent external leakage prevention performance
A bellows seal can be added to valve stems. Increasingly sought-after specifications for gland packings can be applied to comply with fugitive emissions regulations for volatile organic compounds.
High control performance
High control performance is achieved by a combination of wide rangeability and a smart valve positioner.
