T 2036 EN Double adapter Do2, DoS2 Manual adjuster Ma, MaS for temperature, differential pressure and flow regulators Application Suitable for temperature, differential pressure and flow regulators ∙ Double adapter Do2 for attachment of an additional thermostat ∙ Double adapter DoS2 and indication of valve's closed position by a momentary-contact switch Manual adjuster Ma with double adapter and manual override ∙ Manual adjuster MaS with double adapter, manual override and indication of valve's closed position by a momentary-contact switch Double adapter Do2 −− Type 1, Type 4 and Type 9 Temperature Regulators mounted between a Type 2111, 2422 or 2119 Valve and the control thermostat. −− Type 42-24 and Type 42-28 Differential Pressure Regulators as well as Types 42-34, 42-36, 42-37, 42-38 and 42-39 Differential Pressure and Flow Regulators mounted between a Type 2422 or 2423 Valve and the diaphragm actuator. In both cases, the double adapter additionally allows a Type 2231 to Type 2235 Thermostat or a Type 2213 Safety Thermostat to be connected. The largest signal is always used to control the regulator. Fig. 1: Double Type 4 Temperature Regulator, double adapter Do2 and two Type 2231 Control Thermostats Double adapter Do2 and manual adjuster Ma The double adapter and the manual adjuster have a mechanical travel indicator which shows the valve plug position on a scale. Double adapter Do2S The double adapter additionally has a momentary-contact switch which issues a signal to alarm equipment when the valve closes. Manual adjuster Ma A manual adjuster (see Fig. 5) is used with a Do2 in place of the second connection of a thermostat. In this case, only one control thermostat can be connected. Manual adjuster with momentary-contact switch MaS The manual adjuster additionally has a momentary-contact switch which issues a signal to alarm equipment when the valve closes.

Double adapter Do2, DoS2 Manual adjuster Ma, MaS for temperature, differential pressure and flow regulators - 2

Principle of operation The double adapter Do2 is mounted between the valve and control thermostat or diaphragm actuator. The additional control thermostat is attached to connection c. The travel of the mounted unit is directly transferred (connection b) or over the lever (6) to the coupling pin (5) and plug stem (10.1) of the valve. The unit with the largest stroke is coupled to the plug stem. The indicator (5.1) fixed to the coupling pin (5) indicates the travel. The manual adjuster Ma is mounted at connection c (thermostat connection, see Fig. 5). Turning the handwheel (8.1) causes the...
