Standards Compliance: Filter pressure regulating valves must comply with international standards (such as ISO 5599, ISO 6432) and domestic standards (such as GB/T 14525). Some industries (such as natural gas) require special equipment certification (such as TSG D2001).
Selection Considerations:
Media Type: For natural gas, explosion-proof and corrosion-resistant models are required. For compressed air, pay attention to oil content (if oil-free air is used, PTFE seals are necessary).
Environmental Conditions: For high-temperature (>80℃) or low-temperature (<-20℃) conditions, heat-resistant materials are required. For humid environments, enhanced rust prevention treatment is necessary.
Maintenance Cycle: Automatic drain valves reduce the frequency of manual maintenance, and differential pressure gauges can provide early warnings of filter clogging.
