Product Description

Product Description

The NAI-LOK Relief Valve is a high-performance safety valve designed for applications requiring precise pressure control in confined spaces. Its compact design, external adjustability, and robust construction make it ideal for industries such as oil & gas, chemical processing, and power generation.

Key Features & Benefits

 Space-Saving Design - Compact body allows easy installation in tight spaces where traditional relief valves cannot fit.
 Externally Adjustable Cracking Pressure - Fine-tune pressure settings without disassembly, reducing maintenance downtime.
 Lock Wire Capability - Ensures pressure relief settings remain secure, preventing accidental adjustments.
 100% Factory Tested - Guaranteed crack and reseal performance for reliable, leak-free operation.
 Wide Temperature Range - Operates reliably in extreme conditions (-23°C to 204°C / -10°F to 400°F).
 Precision Orifice Size (4.8 mm / 0.19 in) - Optimized flow control for consistent pressure management.
 Outlet Pressure Sensitivity - Cracking pressure adjusts based on downstream conditions for enhanced system safety.
