HRSN Needle Valves

Service valves with a pointed regulating cone for fine regulation of the medium flow

AWP needle valves are equipped with a regulating cone to shut-off and regulate liquid and gaseous mediums. They  are designed for installation in industrial heating and refrigeration systems and are available with various types of connections. The locking and regulating function can be operated with a handwheel or a ratchet. The stem sealing is provided by a threaded bush. The valves are also equipped with a back seal. When the valve is fully open, it is possible to replace the threaded bush and the seal without interrupting operation.
