High Temp. and High Pressure Power Station Gate Valve, the products of Shanghai Power Station Valve Factory Co., Ltd.

High Temp. and High Pressure Power Station Gate Valve, the products of Shanghai Power Station Valve Factory Co., Ltd.

High Temp. and High Pressure Power Station Gate Valve is one of the high-performance products independently developed and produced by Shanghai Power Station Valve Factory Co., Ltd.

01：Forged or Casted Construction

The valve body can adopt forging or casting process according to working conditions and customer requirements, and select different grades of alloy steel according to working parameters and needs to meet high temperature and high pressure or other special requirements.

02： Metal Seated Design

The sealing surface between the valve seat and wedge is STL overlaid, and has undergone high hardening and fine grinding to ensure high hardness and hardness difference of sealing surface, effectively prolonging the service life, and also guarantee the valve seat leakage rate meets the leakage standard

03：Low Torque Design of Switch

The stem surface is precision ground and nitrided, the friction with the packing is small, the scratch resistance and corrosion resistance, effectively reduce the opening and closing torque, and the stem copper nut is supported by needle roller bearings, which is easier to operate.

04：Wedge Double Gate Design

Unique wedge double gate structure, its spherical hinged structure in the process of gate closing, the sealing surface contact has a certain adjustment compensation effect on the wedge angle, automatic correction of processing errors, always maintain the sealing surface 100% matching, with extremely high closing tightness; With the finished valve plate guide rail, the possible jamming phenomenon during the opening and closing of the valve is eliminated to ensure smooth operation. 

05： Pressure Seal Bonnet

When the medium pressure is low, it is sealed by bolt pretension; As the medium pressure rises, the bonnet gradually moves upwards to force the sealing gasket to enhance the sealing performance.

The Operator can be set according to customer requirements such as Manual, Worm Gear, Pneumatic or Electric Actuator,etc.

High Temp. And High Pressure Power Station Valve SDFZ627 Series, nominal pressure PN10.0MPa~63.0MPa, Nominal Diameter DN50~DN600, Body material: WCB、WC9、A105、F22、F91 or other special Alloy Steel. It is applied to Coal-fired power plants, gas-fired power plants and nuclear power plants, as well as petroleum, chemical and metallurgy and other harsh working conditions.
