Body of forged steel
Body in form piece to reduce a number of welds and fittings
Body also available as a single block type – thereby eliminating the nozzle welding seams
Fast switch over, in order to avoid damaging further HP feedwater pipes
Alternatives with a moderation of the closing speed by means of various solutions. This is then required if it is possible for the water to hit and damage the separation wall of the preheater or if the customer specifies the operating times
Simultaneous operation of two main valves with one pilot valve
Open the preheater only after equalization of the pressure – increases safety because work is done behind the valve
System medium operated - no heavy actuator
Alternatives available for selection of the pilot valves
