Wuhan Grat Control Valve Co., Ltd. nukiz@grat.com.cn 86-027-6070-6977
With the optimization and adjustment of the global energy structure, an international energy group urgently requires the installation of high-precision control valves in the DN80 diameter section of long-distance pipeline projects in the Central Asian region, intended for pressure and flow control at urban gate stations. To ensure the efficient and stable operation of the natural gas transmission and distribution system, stringent requirements have been set for critical flow control equipment. Given the flammable and explosive nature of natural gas and the significant fluctuations in working conditions, our company recommends the use of SUS304 stainless steel electric V-type control valves. This product integrates smart positioners and multiple sealing technologies, perfectly adapting to the medium-pressure gas control scenario, helping clients achieve upgrades in digital pipeline management.
Size: DN80
Pressure: PN5000Pa
Medium: Natural gas
Temperature: 50-80℃
Material: SUS304
Power: AC220V
Control signal: 4-20mA
The V-shaped ball valve structure achieves an equal percentage flow characteristic, with a regulation ratio of 100:1, facilitating linear control from fine adjustments of low flow rates to fully open states.
Equipped with a high-resolution servo motor, with a positioning accuracy of ±0.5% and a response time of less than 3 seconds.
The valve seat utilizes a PTFE+graphite composite seal, maintaining zero leakage under conditions ranging from -30℃ to 150℃ (compliant with ANSIVI standards).
With an IP67 protection rating, it adapts to the day-night temperature differential and sand-dust environments in desert regions.
Built-in temperature/vibration sensors support predictive maintenance (optional wireless transmission module available).
Modular structural design allows for valve core replacement without detaching the pipelines, reducing maintenance time by 60%.
The valve rod undergoes plasma nitriding treatment, with a wear-resistant lifespan exceeding 100,000 action cycles.
Certified by ISO15848-1 for micro-leakage, with a service life of over 15 years.
Since the valves have been put into operation for 18 months, significant benefits have been achieved in the following dimensions:
Energy efficiency improvement: Reduces energy consumption of downstream voltage regulators by 12% through precise pressure control
Stability breakthrough: Outlet pressure control deviation < 1.5% at 0.3-4.2MPa inlet pressure fluctuations
Maintenance cost: Compared with the original pneumatic valve, the annual maintenance cost is reduced by about $8,000 per unit
Safety record: 13,000 hours of zero-fail safe operation.
