Low boost buck regulator

Products low boost regulator, DYS-40 low temperature boost regulator DYS-40 low temperature boost regulator DYS-40 low temperature boost regulator DYS-40 boost regulator DYS-40 low temperature rise low pressure regulator valve Overview: cryogenic valve is a single, double seat control valve deformation of the product. It differs from a normal temperature regulating valve that uses a long-necked type valve cover, the filler in work at room temperature. Suitable for medium -60 ~ -250 ℃ cryogenic strong state (such as liquid oxygen, nitrogen, etc.) regulation. To ensure regulation accuracy must be equipped with a positioner. Low temperature valve structure principle: Cryogenic valve by a pneumatic diaphragm actuator and low temperature in single, double seat valve of two parts. The signal input to the pressure regulator chamber pneumatic diaphragm actuator to produce thrust, driven spool by connecting rod, change spool position valve cross-sectional area of ??the flow of change, to achieve the medium flow regulation. Product properties DYS-20 low temperature boost regulator> DYS-20A1 thread within low boost regulator> LNG, O2, N2, Ar boost regulator low boost regulator Cryogenic pressure buildup (PB) regulator Screwed ends Design temperature: -196 ℃ ~ + 80 ℃ Applicable medium: LNG, O2, N2, Ar additional instructions cryogenic valve installation Caution: 1, should be mounted vertically on a horizontal pipe, require horizontal or inclined in exceptional circumstances When installed, the general should be added to the support. Mounted on the wall of the incubator and incubator park board walls should be parallel. 2, should be installed close to the ground or floor place for that maintenance and overhaul of the positioner is equipped with hand wheel or who should ensure observe, adjust and operate and convenient. 3, generally set the bypass pipe so that, when the automatic control system malfunction or maintenance of the control valve is switched to manual operation warrant to stop production. 4, equipped with hand wheel, can be omitted when the line manually bypass line, can be used to limit the valve opening. When to stop using, the hand wheel must be restored to its original neutral position, in order to facilitate automatic control system normally. 5, the installation should be made consistent with the body indicating the flow direction of the medium. 6, the control valve in the pipeline to clean the dirt before installing response, welding slag. After installation, the regulator valve is fully open, for pipes, valves, and other cleaning and test sealing each junction.
