Product Overview
The Swagelok SS-AFSS8 is a precision adjustable pressure relief valve engineered for dependable overpressure protection in industrial fluid and hydraulic systems. Manufactured by Swagelok, a globally recognized authority in high-pressure instrumentation and fluid control, this valve operates on a direct spring-loaded poppet principle. When system pressure exceeds the user-set cracking threshold, the internal poppet lifts off its seat to relieve excess fluid, thereby safeguarding downstream components from pressure spikes and potential rupture. Its adjustable design allows technicians to fine-tune the set pressure within the valve’s rated range, making it a versatile solution for both continuous process control and intermittent safety relief duties in demanding industrial environments.
