Product Description
Feed water system control valve(pressure≤8.0MPa, single-stage balanced cage style)
Performance characteristics:used in boiler feed pipelines, water as medium, medium temperature commonly not more than 215 ºC;
In the debugging and running stage, when boiler runs if the pressure is under load, the difference pressure is very big, generally 8.0-12.0 MPa or so (depending on the pump's feed pressure and boiler's vapor pressure), whereas in the full load normal working state, the differential pressure is generally 2.0-4.0 MPa or so.
Sealing rating is generally level IV
Action frequency: more frequent.
Company Profile
Runh Power Corporation Limited was founded in 1996 as one of the earliest independent EPC contractor of power plant and later incorporated one of the most famous turbine designer and manufacturer, Qingdao ChuangNeng Steam Turbine Co.,Ltd (better known as CNT in China). With subordinate design institute founded in 2001, Runh Power was bestowed upon the capability of providing one-step, package technical solution of thermal, hydraulic, solar, biomass power plant.
Scope of service includes :
A. EPC (Engineering, Purchase & Construction) project of power plant plus financing service.
Power plant project on EPC basis (or "on turnkey basis") is characterized by the overall package solution provided by the contractor. Runh Power's service covers survey all the way till final acceptance.

1. Thermal power plant EPC project
Thermal power plants refer to power plants generating power from fossil fuel, such as coal, heavy oil or natural gas. Thermal power plant, being the most common in the world, has been a speciality of Runh Power since its very foundation.

4. Condensing & double extracting steam turbine: Mostly used for cogeneration purpose. It's structure allows to to produce steam of two sets of parameters, such as temperature, pressure, flow, to be extracted from two exits for different purposes, which makes it popular in industies such as food-processing or phamarciuticals where steam of different parameters are often needed.
