Valve Type:                                                 Shut off globe valve

 

Valve Nominal Size:                                  DN20 through DN300; 0.75 inch through 12 inch

 

Pressure Rating:                                         PN16, 40, 100, 160, 250, 400; ANSI Class 150, 300, 600, 900, 1500, 2500

 

Body Style:                                                  Double top stem guided globe or angle

 

Trim Type:                                                   Unbalanced plug

 

Flow Direction:                                           Flow over the plug; Flow under the plug

 

Flow Characteristic:                                   Quick open

 

Rangeability:                                               50:1

 

Temperature Range:                                 Standard bonnet type from -29°C to 250 °C; Extension type from -100°C to 650°C;

                                          Bellows type from -60°C to 537°C; Cryogenic type down to -196°C

 

Seat Leakage:                                              ANSI V or VI

 

Actuator:                                                      Pneumatic cylinder actuator; Pneumatic diaphragm actuator;

                                          Electric actuator; Hand-wheel manual for option

 

For on-off service, quick open plug is employed. CV1400 control valve is primarily designed to produce maximum flow quickly. 

Attention: most power plant using flow characteristic linear replaced quick open to reduce water hammer as valve’s flow direction is flow to close.
