This reliable precision control valve uses a top-guided, unbalanced trim and an S-shaped flow path. It offers low pressure loss, high flow capacity, a wide control range and accurate flow characteristics. It is suitable for applications with relatively low differential pressure and tight shut-off requirements, regulating flow or pressure. A threaded, replaceable seat simplifies maintenance and extends service life. Flow-to-open operation supports accurate control at small openings. Electric or pneumatic actuation can be selected to suit the operating conditions.
