The new RPEI provides smooth, precise control of fan speed with full-flow relief to protect the system if the fan motor stalls. It combines an electro-proportional adjustable pilot stage and high-capacity main stage to provide precise pressure control inversely proportional to the input electrical current. The pressure setting at zero current is also manually adjustable to allow the system designer to fine tune the RPEI to their specific system requirements.
In fan drive applications, the RPEI electro-proportional inverse relief valve delivers smooth, precise changes in pressure to the fan drive motor to maintain the desired fan speed while also acting as a full flow relief valve for system safety in the event the fan motor stalls. The RPEI defaults to the maximum pressure setting to ensure the fan drive continues to cool in the event of electrical power or signal loss to the XMD driver or valve coil.
Features of the new RPEI include the following:
• 25 gpm (95 l/min) flow capacity.
• Designed and tested to 5 million on-off operational cycles.
• Exceeds new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.
• Standard zinc-nickel plating for 1000 hour salt fog protection.
• Available in two nominal pressure settings: ‘A’ range manually adjustable from 60 to 210 bar; and ‘W’ range manually adjustable from 140 to 350 bar.
• Fully compatible with Sun’s XMD valve drivers for applications requiring closed-loop control.
Hydroformed tube valve body for diaphragm valves
Hydraulic systems & components
