Pressure Control Valve Features
• Self-Operated: The self-operated pressure regulating valve requires no external energy, functioning efficiently without electricity or gas, making it convenient and energy-saving.
• Flexible Action: Designed for flexible operation, it ensures a good seal and minimal pressure set point fluctuation.
• Smart Regulation: Offers precise regulation, takes up minimal space, and is easy to operate.
• Standards Compliance: Complies with AMSE, API, BS, DIN, and GB standards.
• High Adjustment Accuracy: Features a fine range of pressure sections that overlap, providing high adjustment accuracy.
• Sensitive Detection: Equipped with a rubber diaphragm for high detection accuracy and sensitive actuator response.
