1/2in 15in PN16-PN160 High Temperature Resistance Heat Transfer Oil Cast Steel Bellow Seal Globe Valve Applicable Water
Accuracy of adapted working conditions Clarify the properties of the medium: If it is flammable, explosive, or highly corrosive, select materials with corresponding corrosion resistance and explosion-proof ratings; if it is drinking water or other domestic media, ensure that the valve body material complies with hygiene standards. Match operating parameters: Ensure that the valve's pressure and temperature ratings are higher than the long-term working pressure and temperature limit of the pipeline. For example, the pressure rating of a two-way stop valve in an air conditioning scenario should be at least 4.2 MPa.
Compliance qualification guarantee Basic qualifications: The manufacturer must hold the "Special Equipment Production License " issued by the State Administration for Market Regulation. Special scenario qualifications: Valves for explosion-proof conditions should be equipped with a certification of explosion-proof compliance issued by the National Quality Supervision and Inspection Center for Explosion-proof Electrical Products; for government and enterprise projects, it is necessary to confirm that the supplier has passed relevant certifications such as ISO9001 and ISO14001
Quality and delivery reliability Quality control system: Preferentially select suppliers with a full-process inspection process. The product must undergo full-parameter inspections such as appearance, size, pressure, and sealing, and provide a formal inspection report to avoid purchasing substandard products with loose seals or insufficient pressure resistance. Delivery capability: For regular working conditions, select suppliers with regular stock and capable of delivering within 48 hours;
Improved after-sales service Service coverage: Confirm that the supplier has service outlets nationwide, clearly define the emergency response time, and whether they can provide on-site installation and commissioning, operation training, regular inspection, etc. services.
