“When natural gas custom electric valves fail and require shutdown, and the original manufacturer is gone, finding a solution becomes critical. Three suppliers insisted pipe modifications were needed - meaning at least 5 days of downtime for cutting and welding. That translates to significant revenue loss and mandatory safety reporting. Who can handle that?” This real-world scenario from Zhang, an engineer at a natural gas processing plant, reflects a common challenge companies face with obsolete custom electric valves. GRAT’s specialized electric valves capability provides precise solutions for natural gas transportation needs, completely solving the “pipework changes required for valve replacement” problem.
Customer Challenge
Zhang’s facility handles regional natural gas transmission. A critical DN40 custom electric valve failed after years of service, requiring immediate shutdown according to safety protocols. The original manufacturer of this specialized custom electric valve had ceased operations, with all dimensional drawings and material specifications unavailable.
Previous suppliers confirmed: “The flange spacing and bolt hole patterns are non-standard; conventional valves won’t fit. Pipeline modifications are unavoidable - at least 5 days downtime for alterations and testing.” For any natural gas operation, a 5-day shutdown triggers regulatory notifications and requires complete pipeline purging before restarting, creating substantial compliance burdens and operational risks. Zhang needed a solution that guaranteed: “No pipework changes, full compliance, and fast custom electric valves replacement.”
GRAT Custom Electric Valves Solution
Focused on the natural gas application requirements, GRAT’s engineering team completed comprehensive assessment - covering both dimensions and operating parameters - within 30 minutes:
- Mechanical Dimensions: DN40 bore, 280mm flange spacing (non-standard), 80° bolt hole orientation, RF flanged connection
- Operational Parameters: PN100 pressure class, SUS304 valve body material, hard-sealed construction, actuator with AC380V power, 4-20mA DC signal, 1/2NPT electrical connection
“After delivery of our custom electric valves, zero pipework or electrical modifications were necessary. Gas transmission resumed immediately.” The installation team followed strict safety protocols: removing the obsolete valve (nitrogen purging + sealing surface preparation), installing the new custom electric valves (perfect bolt hole alignment + direct electrical integration), and system commissioning (comprehensive leak testing + signal verification). The entire custom electric valves replacement process required just 3 hours to restore full operation, successfully passing all regulatory inspections.
Engineered for Natural Gas Safety & Efficiency
Zhang’s situation demonstrates GRAT’s custom electric valves approach to natural gas applications. The fundamental principle is “complete dimensional and operational compatibility with safety and process requirements”:
- Material Integrity: Selecting compliant materials including SUS304, with full certification, preventing natural gas corrosion
- Sealing Performance: Custom-engineered hard-seat configurations, factory-validated at 1.5 times operating pressure
- Dimensional Accuracy: Advanced metrology ensuring 0.1mm precision, guaranteeing perfect existing pipeline integration
- Electrical Compatibility: Pre-configured for PLC/SCADA system integration, eliminating signal compatibility issues
