My furnace uses a Robertshaw 7000 BKER gas valve and a Robertshaw SP715A ignition control (intermittent pilot), which replaced the original SP710 that failed. I was browsing through the literature for the gas valve last night, and noticed that it states that the valve uses a pick and hold coil for the pilot. According to the literature, the pick coil should be de-energized when the pilot flame is proven, and also states that the pick coil must never be energized when the main valve is energized. However, the wiring harness that came with the SP715A has both the pick and hold wires terminated in the same connector, which is connected to the PV terminal on the control. This means that both the pick and hold coils are energized all the time, including when the main valve is on. What gives? It's been like this for a while and seems to work fine, but the Robertshaw's gas valve literature seems to contradict the way Robertshaw designed the wiring harness.
