Solvent/water based. Instruction manual 305475. For gun mounted fluid regulators, reference instruction manual 307016. This is a back pressure regulator in the P200 series with NPT threading. According to the key, P200 indicates regulation max of 200 bar, R indicates back-pressure regulation action, and M indicates mechanical operating mode. Used in circulating systems to limit supply pressure to a set value by opening an outlet and guiding back excess material when predetermined pressure has been achieved. Referenced in Figure 1 as cutaway example of mechanical back pressure regulator.
