The Furon CDV 2-Way valves with a 1/2 inch orifice have been tested for reliability in 35 wt% hydrochloric acid (HCl) by an independent test lab using the protocol of a major US OEM manufacturer.
Accelerated Life Test Method
Ten valves were assembled in a test manifold allowing parallel flow of 35% HCl through all valves (Figure 1). The valves were cycled approximately ten times per minute under 65 ± 5 psig inlet chemical pressure and actuator pressure of 80 psig.
The acid was supplied to the valves using a double diaphragm pump drawing from a chemical reservoir. Cleanroom grade HCl was filtered through a 0.45 µm filter prior to entering the valve manifold. The acid was replenished every 400,000 cycles to ensure full chemical strength was maintained.
