Minimumflow controlvalve of the recycling system of feed water pump of boiler in power plant The fuction of a boiler feedpump recirculation valve is to insure that adequate flow is maintained through the boiler feedpump to prevent overheating of the pump and cavitation. A minimum flow through the boiler feedpump also protects against erosion and instability caused by cavitation at low flow conditions. Type: straightway connection type: RF &RTJ ANSI B16.5 DN:1",1/2", 2", 3", 4" PN:15 32Mpa Pressure: 900 2500LB Body materials:ASTM A105,F22, F304. F316, F304L,F316L.Moneltitanium alloy etc. or depend on customer's special requests. inner materials: ASTM A276 431, ASTM A276 420, 440C, 630 Stainless steel, 316,316L overlaying welding Stellite alloy. Valve designed on modular assembly principle Circulatory flow impact structure and the pressure to be reduced step by step. With our special technology, we offer a level of expertise that is excellent in providing innovative solutions to the most challenging flow control application in critical working condition(Higher pressure drops). Boiler feed pump stystem Leakage-free pressure-balanced design Low sound level, Easy assembly Designed for preciaion flow control with high pressure, high temperature and aggressive fluids Other shapessuchas single-seat, minitype disc/plug can be available.
