SPVF50 overflow valve KRACHT factory direct supply‌

KRACHT SPVF50A2F1A05 (commonly written as SPVF5OA2F1A05) is a German company's SPVF series direct acting sliding piston low-pressure relief valve, designed specifically for overload protection, pressure stability, and safe unloading of low-pressure hydraulic circuits. SPVF50A2F1A05 has the core advantages of a direct acting slide valve structure, DN50 large flow capacity, precise pressure regulation of 0.5-5 bar, high reliability, and easy maintenance. It is suitable for low-pressure and high flow conditions, effectively preventing system overload, stabilizing pressure, and extending equipment life. It is the preferred overflow valve for industrial low-pressure hydraulic circuits.

Structure and Working Principle

Adopting a direct acting slide valve structure, the core consists of a valve body, sliding piston, pressure regulating spring, adjusting screw, vent hole, and protective cap. The valve body is made of GGG40 ductile iron, which has high strength and impact resistance; The piston is hardened and matched with precision ground valve seats, resulting in minimal leakage; The spring chamber is equipped with pressure compensation and exhaust holes to ensure stable response and no jamming.

Performance characteristics

Large flow capacity: DN50 diameter, 450 L/min high flow rate, low pressure loss (≤ 1.5 bar), suitable for low-pressure high flow circuits.

Accurate and stable pressure regulation: The direct acting structure has a fast response (≤ 50 ms), small pressure fluctuations, and a repeatability of ≤± 0.3% FS, making it suitable for precision pressure control scenarios.

Reliable sealing and long service life: hardened piston and precision valve seat line contact seal, low leakage rate; The valve body is corrosion-resistant and suitable for various media such as hydraulic oil and lubricating oil.

Easy installation and maintenance: modular design, can directly connect pipelines without the need for additional brackets; The top adjustment screw comes with a protective cap, making pressure adjustment convenient. The spring chamber exhaust hole allows for quick exhaust, reducing maintenance costs.

Application scenarios

Widely used in low-pressure and high flow hydraulic systems: engineering machinery (loader, excavator low-pressure circuit), metallurgy (rolling mill lubrication station, electric furnace hydraulic), ships (deck machinery, servo low-pressure section), machine tools (lubrication system, fixture hydraulic), centralized lubrication system, and new energy vehicle battery cooling hydraulic circuit. It is the core component of low-pressure circuit safety protection and pressure stability.
