Stainless spindle with double O-ring sealing. Outer O-ring can be exchanged without draining the system. Models:, and with T-piece. Connection with threaded, soldering, or welding nipples. Models: conically sealing N 1, G / 4 male thread. Connection with HEIMEIER compression fittings for plastic, copper, precision steel, or multi-layer pipes. Operating temperature C to C; with protection cap or actuator up to 0 C. dmissible operating over-pressure P bar. Max. admissible differential pressure: N 1 = 1.0 bar N 0 = 0.7 bar N = 0.0 bar N = 0. bar Construction (black protection cap) Thermostatic insert models with or without presetting ideal for supply temperature control with actuator EMO /0 for all HEIMEIER thermostatic heads and actuators corrosion-resistant gunmetal body universal connection possibilities Corrosion-resistant gunmetal body with Presetting (white protection cap) Thermostatic insert with presetting Setting key

3 Function Thermostatic heads (brochure: Thermostatic Head K with contact or immersion sensor and/or thermostatic heads) are used for proportional control without auxiliary power. When the temperature rises, the angled - passage is closed, and the straight - passage is opened. The EMO 1, EMO EI, EMOLON, and/or EMO / EMO /0 motorized actuators are used for proportional and/or three-step control with auxiliary power (brochure: EMO, EMO EI, EMOLON). pplication Mixing function dmixture control in heating or cooling systems. Variable volume flow in the primary. Constant volume flow in the secondary. istributing function Power control in heating or cooling systems by means of flow rate control. Constant volume flow in the primary. Variable volume flow in the secondary. The EMO T (brochure: EMO T) thermal actuator is used for two-step control with auxiliary power. In the model normally open (NO), the angled - passage is open without, and the straight - passage is closed without current. In the model, normally closed (NC), the angled - passage is closed without current, and the straight - passage is open without current. Principle heating mode 1) with EMO T thermal actuator normally open (NO), or with motorized actuator EMO 1//EI/LON ) Mixing function Primary istributing function Primary Secondary Secondary The models with continuously adjustable presetting enable the adjustment of the necessary volume flow in the outlet. To preset, the setting key is slipped onto the valve insert, and the desired value is set. The setting values are displayed on the front of the valve insert. Without an instrument, the presetting cannot be manipulated by unauthorised persons. with thermostatic head or with EMO T thermal actuator normally closed (NC) Mixing function Primary istributing function Primary Secondary Secondary Examples of use Supply temperature control for floor heating manifolds with thermostatic head K with contact sensor. 1) For cooling, the connection of inlets and must be exchanged. ) The effective direction of the EMO 1//EI/LON motorized actuators is determined by the controller or the connection. Water-side control of fan-coil appliances (air-conditioning systems / fan-coil units), e. g. with EMO T (NO). Heating support for bivalent solar facilities with EMO T (NO), for example. dmixture control in the heating with EMO /0, for example. Supply temperature control by means of admixture control in the heating with EMO /0. Information To prevent damage and incrustation in hot water heating systems, the composition of the heat transfer medium should meet VI [German Engineer ssociation] directive 0. The instruction leaflet of the VdTÜV [German ssociation of Technical Inspection uthorities] Return temperature increase for solid-fuel boilers with thermostatic head K with contact sensor. Globo P Floor heating manifold Oil/gas boiler Radiator Fan/coil unit Solid-fuel boiler Solar collector Combined solar storage tank 1466/GFW-Merkblatt /1 must be observed for industrial and long-distance energy systems. Mineral oil or mineral-oil based lubricants of all kinds in the heat transfer medium lead to considerable swelling and, in most cases, to a failure of EPM seals. When using non-nitrite antifreeze and anti-corrosive agents based on ethylene glycol, please read the respective particulars-especially on the concentration of the individual additives-in the manufacturer s documentation.
