Electric flange gate valve

Electric flange gate valveAction distance ratiopneumatic valveLarge, the opening and closing speed of pneumatic valves can be adjusted, with a simple structure and easy maintenance. Due to the buffering characteristics of the gas itself during the operation, it is not easy to be damaged due to jamming, but there must be a gas source, and its control system is alsoElectric ValveComplex.Electric flange gate valveSensitive response, safe and reliable, many factories with high control requirements set up compressed air stations specifically for pneumatic instrument control components. Electric devices require electricity and can control their flow rate.

Electric flange gate valveanalyze

ChinaElectric ValveWith the continuous development of science and technology, the product market is also moving towards high technological content, high parameters, strong corrosion resistance, and high lifespan. Based on the analysis of domestic and foreign electric valve technology and the market demand for electric valves at home and abroad, the development trends and investment directions of industrial electric valves and high-tech in the electric valve industry in various industries in recent years have been studied, as follows:

1. Oil and natural gasWellhead equipmentUsing valves

The valves used in oil and gas wellhead equipment are mainly in compliance with the requirements of the United StatesAPI6A standard single or double gate valves, forged steel parallel gate valves with or without diversion holes, mud valves, angle throttle valves, oilfield specific parallel control valves, oilfield specific straight through check valves, injection/polymer specific parallel gate valves, clamp type parallel gate valvesPilot operated safety valveAnd check valve.

The nominal pressure level of electric valves used in oil and gas wellhead equipment isAPI2000psi、3000psi、5000psi、10000psi、15000psi、20000psi； The nominal diameter is DN46~228mm (113/16in~9in); The temperature levels are K (-60~182 ℃), L (-42~182 ℃), P (-29~182 ℃), R (room temperature), S (-18~166 ℃), T (-18~182 ℃), U (-18~121 ℃), V (2~121 ℃); The material requirements are AA, BB, CC, DD, EE, FF, HH; The material performance requirements are 36K, 45K, 60K, and 75K; The product technical requirements are based on PSL1 (Product Specification Level 1), PSL2 (Product Specification Level 2), PSL3 (Product Specification Level 3), and PSL4 (Product Specification Level 4).

2. Valves for long-distance oil and gas pipelines

Valves used in long-distance oil and gas pipelines are mainly in compliance with the requirements of the United StatesSingle or double gate, with or without diversion holes according to API6D standardFlat gate valveForged steel or cast steel three body, top mounted or fully welded fixed ball valves; Oil sealed or pressure balanced plug valve; Swing orButterfly Check ValveBall check valve; Cleaning valves, etc.

theseElectric ValveThe nominal pressure level isCL150(PN2.0MPa)、CL300(PN5.0MPa)、CL400(PN6.4MPa)、CL600(PN10.0MPa)、CL900(PN15.0MPa)、CL1500(PN25.0MPa)、CL2500(PN42.0MPa)； The nominal diameter is DN50~1500mm (2in~60in); The technical requirements for fire resistance testing shall comply with ISO10497; The pressure test of electric valves shall be conducted in accordance with ISO520
