Imported Boiler blowdown valve periodically (Shenzhen imported boiler blowdown valve periodically to ensure high price - steam control valve)
Imported Boiler blowdown valve periodically, is a multi-level air defense of the relief valve. Specially designed valve member such that the fluid progressively buck, control the flow and prevent cavitation damage; throttle portion separated from the sealing surface, the effective protection of the sealing surface. Trim surface hardening, hardness HRC70 left
Right, erosion resistance, long life; spool face opened a big gap, the fluid-containing particles, the spool will not stuck. The valve is used in power plants regularly excluded boiler water insoluble impurities precipitate ideal solution.
Control valve parameters: Trim characteristic: the imbalance within the top guide member structure Multistage Throttle core structure Body type: straight-through angle type Bonnet forms: Standard Thermally Flow characteristics: equal percentage linear quick opening Diameter range: DN25-50 (1 "-2") Pressure rating: PN25,32Mpa (ANSI 1500,2500LB) Leakage class: ASME B16.104 Ⅴ (Standard metal seat) Pipe connection: flanged welded formula Temperature range: less than 420 ° Actuator Type: pneumatic diaphragm actuator Pneumatic piston actuator Electric actuator Location: United States Product Brand: Ou (OKE)
