Kromschroeder 03089067 spring 300-550 mbar, orange/green for JSAV 50-100

Overpressure spring (upper limit adjustment spring) Kromschroder 03089067 for safety shut-off valves JSAV 50-100 (300–550 mbar, orange-green). This is an original replacement spring for safety shut-off valves (SSV) of the JSAV 50, 80 and 100 series, designed for setting the upper pressure trip threshold. It is installed after the pressure regulator and cuts off gas supply in case of emergency pressure rise above 550 mbar, protecting the burner and fittings from damage. Technical specifications: Parameter Value; Part numbers 03089067, 624.625.045; Manufacturer Kromschroder / Honeywell (Germany); Part type Upper limit spring (Obergrenzenfeder); Compatibility JSAV 50, JSAV 80, JSAV 100 (DN50, DN80, DN100); Setting range Pdo (emergency threshold) 300 – 550 mbar (0.3 – 0.55 bar); Color coding Orange-green; Material High-quality spring steel; Weight 0.025 – 0.03 kg; Operating temperature -15°C to +60°C; Application Natural gas, liquefied gas (propane-butane), biogas, hydrogen. ✅ Key advantages: High emergency threshold 550 mbar: This spring has the highest setting range in the JSAV line (300–550 mbar) and is intended for systems where the pressure regulator may pass gas at up to 5.5 bar, requiring reliable protection under extreme loads. Easy identification by color: Unique color coding (orange-green) allows quick and error-free identification of the trip range, critical for service personnel. Original Kromschroder quality: The spring is made of high-quality steel, resistant to deformation and corrosion, maintains elasticity and stable trip threshold throughout its service life. Certified safety: Fully complies with European gas safety standards.
