The 1-2480 series control valves are used for high pressure drop and angular travel up to 80° on liquid and gas services. For more critical service a special execution with extended wings and angular travel up to 100° is available.
A double eccentric disc which reduces torque requirements and seal ring wear by minimizing its contact with the disc.
The 1-2480 series flanged control valves have a double eccentric disc which reduces torque requirements and seal ring wear by minimizing its contact with the disc.
Additional torque reduction is obtained by the profiled drilled integral wings of the design 1-2483.
The drilled wings of 1-2483 make the valve suitable for flow control in cavitating services on liquids and for low
noise flow control on compressible fluids.
Due to the eccentric design of the disc, these valves can provide a stable flow control with limited negative
gradients and excellent shut-off in closed position.
Also the flow characteristic is improved and it is close to an equal percentage shape for low openings.
The reduction of flow coefficients due to the wings is balanced by higher values of factors FL, xT and xFZ which
allow the use of this valves for high pressure drop and angular travel up to 80° on liquid and gas services.
For more critical service a special execution with extended wings and angular travel up to 100° is available.
Valves are available with A216 WCB, AISI 316, AISI 316L, A890 4A duplex stainless steel body and size up to 80".
