Natural Gas Pressure Reducing Regulators, 4 Inch, 125 LB

Key Specifications / Features

The pressure regulating valve, a crucial nitrogen sealing apparatus, consists of a control valve, actuator, pressure spring, pilot, pulse pipe, and ancillary components. Its primary function is to uphold gas pressure, typically nitrogen, atop a vessel, thereby averting material exposure to air, preventing volatilization and oxidation, and ensuring vessel integrity. Especially adept for safeguarding gas containment systems in sizable storage tanks, this product boasts energy efficiency, swift responsiveness, dependable operation, and user-friendly maintenance. Its versatility extends across various sectors including petroleum, chemical industries, among others, where it finds widespread application.
