About Product
The Onus PFH-004 is a direct acting, high-performance pressure regulator engineered for reliable performance in high-pressure applications. Designed with a balanced inlet mechanism, this regulator ensures stable downstream pressure, even under fluctuating inlet conditions or varying flow demands.
Capable of handling inlet pressures up to 210 bar(g) and beyond, the PFH-004 is suitable for a wide range of industrial environments, including those requiring rugged, corrosion-resistant materials. Its balanced design significantly reduces the impact of inlet pressure changes, helping maintain consistent set pressure and optimal system performance.
With its robust construction and high flow capacity, the PFH-004 delivers both strength and precision—making it an ideal solution for critical control in gas and fluid handling systems.
• SELF-CONTAINED OPERATION
Operates entirely on process pressure—no need for compressed air, electricity, or external actuation systems. Perfect for remote or energy-independent applications.
• STABLE & ACCURATE PRESSURE REGULATION
Designed to deliver highly accurate downstream pressure control, even under varying flow and inlet conditions, ensuring process consistency and efficiency.
• IN-LINE SERVICEABILITY
Internal components can be accessed for inspection or replacement without removing the valve from the line, significantly reducing maintenance time and system downtime.
• TAMPER-RESISTANT ADJUSTMENT
Equipped with a secured adjustment cap and screw, the design discourages unauthorized or accidental changes to pressure settings in the field.
• REINFORCED DIAPHRAGM ASSEMBLY
A specially designed load-bearing diaphragm prevents damage under high-stress conditions, improving safety and extending service life.
• LEAK-TIGHT SEALING
Dual sealing—metal-to-metal and soft seat—delivers exceptional tight shut-off performance, complying with ANSI FCI 70.2 Class VI leakage standards.
