Flanged Ends UV236
Description: Shut-off valves series UV226 and UV236 are handwheel valves that excel with unique features suitable for a long-time no maintenance service. If a bellow is used, it ensures a hermetic tightness to environment and in addition it is added with a safety packing made of graphite. Valves with graphite packing are equipped with back seat. The most advantageous feature is low linear forces when opening or closing the valve which does not change during the life-time. Thanks to the yoke design, the valve can be easily insulated and its handwheel can be operated even at high temperatures of process medium. The handwheel is non-rising, which enables the valves application in unaccessible places. The visible indicator ensures an easy identification of the position.
Application: The valves are especially designed for applications in warmwater and steam circuits in power plants, heating plants, heatexchange stations, heat transferring stations and common heating applications. Thanks to a great scale of available valve sizes, the valve is suitable for a tight closing
(shutting down) of main branches, by-passes, extracting and sampling pipelines. The used materials enable the valves to be installed also in air-conditioning, refrigerating and other special applications.
Process media: The valves UV226 and UV236 are suitable for shutting off water, water vapour and other liquids and gases which are compatible with used materials of the valve body and internal materials. The valves UV226 (Ex) and UV236 (Ex) can be also used for industrial and heating gases and flammable liquids. To ensure a long-life of a valve seat, we recomend the installation of a strainer in front of the valve or to ensure in any other way that process medium does not contain abrasive particles or impurities.
Installation: The valves can be installed in any position, except execution V and B. The valves of execution V and B must be installed only in horizontal position to the vertical axis of the spindle. It is recommended to ensure enough space for hand wheel operating. The flow direction is indicated by the arrows on the valve body. The alternate flow direction through the valve is permissible, except execution V and B. Detailed information is given in the instruction for installation and service which is standard part of delivery.
