(Summary description)Brief introduction of power station valve "Power station valve" is also called special valve for power station. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, the power station valve is characterized by high temperature and high pressure, and a unique self-sealing design. The higher the pressure, the more reliable the sealing. Due to the special performance and technical characteristics and the special working conditions, the product also has characteristics that cannot be replaced by other products.

Information
Brief introduction of power station valve
"Power station valve" is also called special valve for power station. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, the power station valve is characterized by high temperature and high pressure, and a unique self-sealing design. The higher the pressure, the more reliable the sealing. Due to the special performance and technical characteristics and the special working conditions, the product also has characteristics that cannot be replaced by other products.
Main design specification for power station valve
Design and manufacture GB/T12234 ASMEB16.34
Structure length JB/T3595
Interface connection size JB/T3595 GB/T12224
Inspection and Test JB/T3595 MSS SP61
Pressure and temperature reference JB/T3595 ANSI B16.34
Main pressure level of power station valve
Nominal pressure 200, 250, 320
Working pressure P 55 100V, P 55 140V, P 55 170V
Structural advantage
1. The pressure self-tightening seal is adopted, and both ends of the valve body branch pipe are welded.
2. The valve seat and valve disc sealing surface are made of cobalt-based hard alloy surfacing or plasma spray welding, with good high temperature resistance, wear resistance and scratch resistance.
3. The valve stem is treated with anti-corrosion nitriding, which has good corrosion resistance and scratch resistance.
Basic classification
Power station gate valve, power station stop valve, power station check valve, high temperature and high pressure power station valve
