- Model RV 111 - Control Valve



The valves series RV 111 COMAR are control valves of a compact construction with external threaded coupling connection. The valves excel with minimum dimensions and weight, quality control function and a high tightness in closed position. Thanks to an unique LDMspline, flow characteristic, which has been optimized for thermodynamic processes control, the valves are ideal for applications in heating and air-conditioning. In regard of a sophisticated design of internal parts and long service life of packing, the valves fulfill every demand for a long-time service without necessary maintanance. 

The valves are optionally manufactured either two-way or three-way. The part of the delivery is a screw joint enabling a quick and easy installation to an appliance. Assembled with ANT5 actuators of LDM and actuators Siemens (Landis & Staefa), the valves can be controlled with 3-point or continuous signal. The part of the delivery is also a hand wheel which can be used for the valve control untill assembling with an actuator.

Used materials for throttling trim which consists of plug made of high-quality stainless steel and soft sealing elemnts, ensure a hermetic tightness in both ports and enable the valves to be used not only in common warm-water and hot-water regulation circuits in heating but also in applications with special characteristic features of process medium such as in refrigerating industry and air-conditioning.

The valves series RV 111 are suitable for applications where process medium is water or air. Further they can be used for refrigerating media and other non-aggressive liquids or gases with temperature ranging from +2°C to +150°C. Sealing surfaces of control trim are resistant to common sludge or water impurities. Yet it is recommended to pipe a strainer in front of valve to ensure a reliable function and tightness in case there are abrasive particles present.
