We stock the PSX3 in 2" NPT with OPSO, UPSO, and all spring ranges. Other connection sizes are available to order — Contact Us to confirm lead time and configure your unit. The BelGAS PSX3 standalone slam shut valve is built for wherever instantaneous termination of pressure transference is needed. Operating on preset values, the PSX3 automatically stops downstream flow the instant pipeline pressure exceeds the upper set limit or drops below the lower set limit — protecting downstream equipment from overpressure and ensuring gas flow shuts down if pressure drops below what's needed to maintain pilot light or critical flow. Once tripped, the PSX3 requires a manual reset before flow can resume, so the system stays shut down until it's been inspected and confirmed safe. We carry the PSX3 in OPSO (overpressure shut-off), UPSO (underpressure shut-off), and combined OPSO/UPSO configurations, across all available spring ranges. The valve comes in either internal or external pressure registration, with easy conversion between the two — so one unit can be field-configured to match your application without ordering a different model. As a standalone slam shut, the PSX3 can be installed independently or paired with a separate regulator to add a dedicated layer of overpressure/underpressure protection anywhere code or good practice calls for it — gate stations, farm taps, and any setup where you want shut-off protection isolated from the regulating function itself. Features: OPSO (overpressure shut-off) and UPSO (underpressure shut-off) protection All spring ranges in stock Field-convertible between internal and external pressure registration Manual reset required after trip — system stays down until inspected Molded seat assembly (Nitrile / Aluminum) Lead seal and wire available (tamper protection) Rebuild kits available Applications: Industrial and commercial gas systems Pressure protection for gas engines Standalone or paired with service regulators Gate stations and farm taps Product Documentation: PSX3 Spec Sheet PSX3 Installation & Operation Manual (IOM) Specifications Spec Detail Model / Series PSX3 Type Standalone slam shut valve — OPSO / UPSO Port Size 2" NPT — in stock.
