V130 operated flow control valve operated flow control valve -> http://www.bub-valve.com/showproduct.asp?id=436 is a need for any external drive energy, rely on media pressure to be transferred as power source its medium pressure branched, energy-saving control device to automatically adjust the settings. It sets the detection, control, and perform many other functions in a valve own independent instrument control side by low flow resistance single seat (sleeve) body, pressure balance, directing and implementing agencies. The basic design of the technical specifications: GB / T 17213.1 test: ASME B16.104 Product Specifications Model: V130D05 V131D05 size range: DN15 ~ DN250 Pressure rating: 1.6 ~ 4.0MPa shell material: carbon steel, stainless steel Suitable medium: gas, liquid , steam operation: automatic 【Features】 no external drive energy energy-saving automatic control system. The low cost of equipment; adjustable set point and the range is wide. Facilitate continuous adjustment of the flow within a set range; command and operational direct acting type fast dynamic response. High precision, adjustable ratio; pressure balance valve bodies, responsive, precise control of the regulating valve, allowing the pressure large. Both the hard seal (V130D05) and soft seal (V131D05) sealed form of self-regulating valve -> http://www.bub-valve.com/product2.asp?cateid=104 standard Bo valve Shanghai Co., Ltd.
