Boiler feed valve, also fulfilling the role of a starting valve. A cast body, material G17CrMo9-10 (1.7379), with a self-tightening bonnet. The main plug is controlled by an auxiliary plug (pilot), flow over the plug (FTC). A multi-step pilot allows to regulate small flows at big pressure reductions without the risk of cavitation occurring. The main plug: two-step up to the middle of lift, with resistance elements (plates). When opened wider, no internal throttling; the function of filling the boiler is carried out at a small pressure reduced. A protective cage on the seat. It is highly air-tight Reducing and cooling station. An angle steam power reduction valve DN25 / DN150, is made of X10CrMoVNb9-1 (1.4903). A multistage plug and resistance plates on the outflow aiming at elimination of choked flow and limiting the noise levels. The cooling chamber is an integral part of the valve. A lance desuperheater, an injection valve with an anti-cavitation structure. STEAM WATER 18 SPECIAL VALVES
Steam reduction valve. An angular body made of 13CrMo4-5 (1.7335). A self-tightening bonnet. The main plug: cage type, controlled by an auxiliary plug (pilot).
