Product features

The electric high pressure gate valve is an integral straight through casting (forging) valve, which consists of a high pressure gate valve and an electric actuator. The middle part is connected by a valve cover. The valve body is made of chrome molybdenum vanadium steel, and the sealing ring is made of low-carbon steel or flexible graphite 316 wire (mesh). It has good sealing performance under high temperature and high pressure conditions. The electric high pressure gate valve is suitable for working pressure of 10MPa~25MPa, It is widely used in pipelines of water, steam, oil products and superheated steam under medium conditions with temperature ≤ 550 ℃.
Standard specification for electric high pressure gate valve:
Structure length: GB/T12221
Flange size: JB79
Inspection and test: JB/T9092
Carbon steel: GB/T12229
Stainless steel: GB/T12230

Protection grade: IP55 (customizable IP67)
Explosion proof sign: Exd Ⅱ BT4
Ambient temperature: - 20~+60 ℃
Ambient humidity: ≤ 90%

Structure Diagram of Electric High Pressure Gate Valve
Structural features of electric high-pressure gate valve:
 
1. The valve adopts pressure self tightening seal or valve body and bonnet gasket seal structure, which is safe and reliable.
2. The valve disc adopts the structure of double gate plates with universal roof in the middle, which can automatically adjust the fitting degree of the valve disc and the sealing surface of the valve seat to ensure the sealing of the valve. This structure is convenient for maintenance and cost saving, and the valve disc has good interchangeability.
3. The sealing surface of valve disc and valve seat is made of cobalt chromium tungsten carbide by plasma spray welding, with high hardness, abrasion resistance, scratch resistance and long service life.
4. The valve rod is made of nitrided steel, with nitrided surface, high hardness, scratch resistance, corrosion resistance and long service life.
5. The electric device is equipped with a torque control mechanism, a field operating mechanism, and a manual and electric switching mechanism.
