The supplied Bypass Stations are

comprised of qty 3 Steam pressure

reduction and steam conditioning

systems.

The first HP Bypass system includes

qty 2 Bypass Valves angle type, size

10" #2500 x #900 BW in A182 F22. The

trim is Extra Low Noise type, complete

with pilot plug.

Downstream the valve seat, directly

mounted into the injection chamber,

there is a double stages silencer to

reduce the noise generated from the

valve trim before the water injection.

The injection chamber is full integrated downstream the valve seat and is provided with a wall mounted desuperheating system made

up of water spray nozzles (variable area, spring type).

The HP Bypass valves are equipped with Valvitalia Pneumatic Double Acting actuators, fail last, sized for a quick opening/closing time

of less than 5 seconds in trip mode.

The second HP Bypass system includes qty 1 Bypass valve angle type, 10x16" #2500 x #600 in A182 F22.

Provided with Low Noise trim and pilot plug, the Bypass valve is designed with integrated double stage silencer and 16” injection

chamber. The desuperheating section, wall mounted on the injection chamber, is provided with variable area-spring assisted water

spray nozzles.

The Valvitalia Pneumatic Double Acting actuator guarantees 5 seconds quick opening/closing time.

The supplied IP Bypass system is made up of qty 2 Bypass Valves angle type 12x14" #600 x #300 BW in A105.

The valve trim is Low noise type and the steam conditioning is realized through the water spray nozzles wall mounted in the integrated

injection chamber (14”).

The valve is provided with Valvitalia Pneumatic Diaphragm actuator, spring return, with fail position “last”.
