Part 234261 is the npt version (P20-RM DN1 npt) with identical specifications. Based on model designation key: P20 = 20 bar pressure regulation max, R = back-pressure regulation, M = mechanical operating mode, DN1 = valve seat orifice size Part of the back pressure regulators family used in circulating systems This part is mentioned in the header as one of the Mechanical Back Pressure Regulators covered by this parts diagram. It uses the same housing (lower) as 233758, the same seat as other models in the family, the same O-RING as 233758/234261/234262, the same cover and compression spring as other models, and the same plunger as 233758/234261/234262. It's a non-npt model that uses parts 15Y036 (O-RING), 15A219 (RING), and 245373 (PLUNGER, valve).
