The OB-30 Temperature Regulator from Yoshitake are a versatile and compact temperature regular for Steam and Hot Water Applications. The thermal capability of the valve can be adjusted by changing the thermal bulb attached to the valve (thermal bulb connection is common size among all thread sizes). The setting of the initial temperature is then a case of adjusting the top handle until the desired set point is reached. This bronze bodied valve features a Stainless Steel Valve & PTFE seat which offered excellent durability and high sealability. The single valve and balance bellows structure offers stable temperature control without being affected by inlet pressure fluctuations. A range of sensors and thermowells are available to suit this valve.
