1. Material Selection & Preparation: High-grade materials are chosen for their specific properties to withstand high pressures, varied temperatures, and chemical exposure. For critical components exposed to natural gas, forged steel (e.g., ASTM A105, A350 LF2) or stainless steel (e.g., SS304, SS316) is often preferred for its exceptional strength and corrosion resistance. Elastomeric components, such as diaphragms and O-rings, are selected from specialized HNBR or FKM compounds, ensuring long-term flexibility and chemical compatibility with various gas compositions.
2. Casting/Forging & CNC Machining: Body and bonnet components are typically produced via precision casting or hot forging to achieve superior metallurgical integrity and reduce internal stresses. This foundation is crucial for structural robustness. This is followed by advanced CNC machining, where intricate internal geometries and critical sealing surfaces are brought to exact tolerances, typically within ±0.01mm. This precision is vital for the regulator's responsiveness, leak-tightness, and overall flow characteristics.
3. Component Assembly: In a controlled cleanroom environment, skilled technicians meticulously assemble the diaphragm, springs, valve seat, and other internal mechanisms. Careful attention is paid to torque specifications and alignment to ensure optimal performance. The integration of advanced sealing technologies is key to minimizing fugitive emissions and enhancing overall system integrity.
4. Testing & Calibration: Every single unit undergoes rigorous testing, far exceeding standard requirements. This includes hydrostatic pressure testing (e.g., 1.5 times the maximum allowable working pressure per ASME B16.34), pneumatic seat leakage tests (e.g., to ANSI/FCI 70-2 Class VI standards), and functional performance tests across the entire flow range. Calibration is performed to ensure the outlet pressure remains within specified narrow bands (e.g., Accuracy Class AC10, Lock-up Pressure SG20), even with fluctuating inlet pressures and varying flow rates. Our products boast a design service life of over 20 years under typical operating conditions.
5. Surface Treatment & Finishing: Components may undergo specialized surface treatments, such as phosphating or epoxy coating, to enhance corrosion resistance, particularly for outdoor or harsh industrial environments. Final inspection checks for aesthetics, marking, and secure packaging.

This rigorous process ensures that each RTJ2-DKQ series unit is delivered with the highest quality, ready for demanding applications in target industries such as petrochemical, metallurgy, power generation, and urban gas distribution, where energy saving and corrosion resistance are paramount.
