A single-seat control valve with large Cv value, high rangeability, and accurate flow control performance.
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.
Metal seat tight shutoff (class IV, V) and soft seat tight shutoff (class VI) are available.
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 is achieved by a combination of wide rangeability and a smart valve positioner.
