Single Seated Control Valve
DLS small-port single-seated control valves are suitable for all general applications over a wide range of pressure drops and temperatures where flow rate is fairly small,The compact valve body,having S-shape flow passage that features low pressure loss,allows a large flow capacity,rangebility,and high accuracy flow characteristics which comply with the IEC standards.
The valve plugs are availabie in a wide range of CV values,The seat leakage performance performance complies with the ANSI standards,The valve is actuated by a new compact and powerful diaphragm actuator loaded with multiple springs.
Main Performance:
1.Valve size:20,25mm
2.Pressure rating:JIS 10K,20K,30K,40K,ANSI CLASS 150,300,600 PN1.6,4.0,6.4
3. End connection:Flanged end:RF and RJ, welded end:SW
4.Seat leakage:metal seat:ANSI Class IV,soft seat:ANSI Class VI
5.Hysteresis error:3%FS(without positioner),1%FS(with positioner)
6.Linearity:±5%FS(without positioner), ±1%FS(with positioner)
