All rights reserved.*VHB2 & VHB 3Protects the feedwater heater steam jacket in case of tube rupture or leakage. Protects the turbine extraction from excessive backpressure. Or water carry over Allows the feedwater heater to be isolated from the system without disrupting the circulation through the plant. Allows bypassing of the feedwater heater during plant start-up at low turbine load. Allows bypassing of the feedwater heater at peak loads to increase output from the turbine. null© 2006. CCI – Control Components Inc. All rights reserved.*Feedwater Heater Bypass ValveFunction of VHB3 Feed Heater Bypass© 2006. CCI – Control Components Inc. All rights reserved.*Function of VHB3 Feed Heater BypassThe bypass system is always in stand-by position, When the water level rises, the feedwater heater bypass valve will open and bypass the feedwater around the heater When the pressure increases in the steam heating line. The switch-over is automatic and can be very fast. Resetting the system to normal operating mode can be done manually or automatically The VHB-3 passes the feedwater from the feed water pump side, to the feedwater heater or to the bypass VHBS-2 is installed at the feedwater heater outlet side. VHBS-3 is available in a three-way versionUnder normal conditions© 2006. CCI – Control Components Inc. All rights reserved.*Under normal conditionsthe feedheater is on-line, the bypass piping is filled with pressurized water, but is shut down on its upstream side. Resetting the system to normal conditions, i.e. passing the fluid again through the feedheater, is usually done slowly and carefully by local manual actions but can also be done remotely.null© 2006.

The dump valve shall close and the on/off valve ‘B’ shall stay closed. The filling valve ‘C’ will refill/pressurize the FWH and piping. When the pressure is equalized the plug will move to normal position The valve is now back in normal mode operation. VHB-T3WHVHB 3, Self acting Hydraulics Normal to Bypass Mode© 2006. CCI – Control Components Inc. All rights reserved.*VHB 3, Self acting Hydraulics Normal to Bypass ModeThe upper chamber is pressurized through the valve A. The on/off valve B opens and evacuates the pressure in the lower chamber of the actuator. The plug isolates the FWH. The VHBS is connected to the same control system and works in parallel with the VHB-3. When the FWH is isolated, the dump valve is opened to depressurize and drain the FWH and piping. The internal pressure in the valves acting on the plugs secures the plug position in bypass mode. The manual hand wheel is turned to lock the plug-stem The hand wheel is secured with a pad lock. When the limit switches for the plug and the hand wheel are activated, the on/off valve B can be closednull© 2006. CCI – Control Components Inc.

CCI – Control Components Inc. All rights reserved.*Standard VHB3 for Pneumatic and Electric Actuation, Normal mode to Bypass modeThe valve plug is positioned so that the flow is allowed to pass through the feedwater heater & the by-pass line closed. The internal pressure acting on the plug results in a force, which tends to maintain the plug closed. The actuator is also acting in this direction to secure a shut-off towards the bypass line. The feedwater from the FWH passes through to the VHBS2or 3. The internal pressure in the valve, acting on the plug, tends to keep the valve open. The actuator is also acting in the same direction to secure the free passage from the FWH to the boiler.Standard VHB3 for Pneumatic and Electric Actuation, Bypass mode© 2006. CCI – Control Components Inc. All rights reserved.*Standard VHB3 for Pneumatic and Electric Actuation, Bypass modeWhen the water level activates the level switch, the feedwater heater bypass system switches the VHB-3 to close the passage to the FWH and opens the bypass line. At the same time, VHBS will close the passage to the FWH, and the FWH is isolated Other signals, such as hi steam pressure, will switch the valves. Manual opening of the bypass system is performed the same way, except that the signal to open is generated in the control room The VHB valves cannot be stroked while in bypass mode due to the large pressure differential over the plugs as the actuator has insufficient force.

CCI – Control Components Inc. All rights reserved.*Valve BodyThe valve is manufactured from fully machined forgings with a body shape of smooth design and all body penetrations circular to prevent asymmetrical stress patterns. Connections are adapted to the connecting piping. Material is typically carbon steel, WB36 or CrMo low alloy steel.Bonnet © 2006. CCI – Control Components Inc.

All internal parts can be removed through the bonnet cavity. Material is typically CrMo low alloy steel, but can be Carbon Steel if required.
