Product Details:

FOXBORO B0123HE is a precision pneumatic pressure regulator, a heavy-duty air control valve built for process automation. This regulator adopts corrosion-resistant metal housing, protecting internal diaphragm and valve components from dust, moisture and chemical vapors in industrial workshops. The mechanical pressure adjustment knob allows operators to set stable output air pressure on site without power supply. It adopts force-balance principle to maintain constant outlet pressure even when inlet pressure or air flow fluctuates, delivering reliable pneumatic pressure supply for valve positioners, pneumatic actuators and other field pneumatic instruments.

This FOXBORO B0123HE air control valve reduces high inlet compressed air to stable preset outlet pressure. The built-in diaphragm and pintle valve assembly automatically compensates pressure deviation. It features internal relief function: when outlet pressure exceeds set value, excess air will be exhausted automatically to prevent overpressure damage to downstream pneumatic equipment. The matching repair kit B0127VS can replace diaphragm and internal wearing parts for regular maintenance. It supports inline air pipeline installation, and filter screen at air inlet can block particle impurities to avoid internal valve blockage. This device requires no electric power, suitable for explosion-risk field areas.

This pneumatic pressure regulator has excellent vibration resistance and chemical tolerance, supporting long-term stable operation in chemical, oil & gas, power and pulp & paper plants. It is widely used to provide stable pneumatic source for field control loops. It can be deployed for new pneumatic instrument project construction, and also serves as spare parts to replace aging pressure regulators on legacy pneumatic control systems. Every FOXBORO B0123HE regulator passes strict factory pressure testing before shipment to guarantee stable pressure control performance for process automation.
