SUN LPBCXFN Direct‑Acting Relief Valve – Fast Response for High‑Flow Systems
-
The SUN LPBCXFN is a direct‑acting relief valve designed for applications requiring instantaneous pressure limiting. Its poppet‑type construction provides a large flow capacity with minimal pressure drop, making it suitable for high‑flow circuits such as fan drives and conveyor systems. The valve features a tamper‑proof adjustment option and a compact envelope that fits SUN’s standard cavities. With its simple, reliable design, it ensures system safety without complex pilot lines, reducing installation cost and potential leakage points.

Product Description
The LPBCXFN offers a straightforward yet highly effective solution for overpressure protection in demanding Hydraulic Systems. Direct‑acting operation means the valve responds immediately to pressure rises, limiting spikes that could damage sensitive components. The poppet is hardened and ground to ensure a tight seal and long service life, even with frequent cycling. Flow capacity is maximised through large internal passages, and the pressure‑flow characteristic is nearly flat, providing stable control across a wide flow range. Adjustment is performed via a hand knob or hex screw, depending on the variant, and the valve can be ordered with factory‑preset settings for applications where user adjustment is undesired. The exterior is treated with a durable coating to resist rust and chemical attack. Common uses include hydraulic power units, test rigs, and lifting equipment where rapid pressure relief is essential. The LPBCXFN is compatible with most hydraulic fluids and operates effectively in temperatures from -40°C to +120°C. Its cartridge design enables easy replacement without disturbing pipework.
