ZJFF (H) Pneumatic Thin Film Three way Split (Close) Flow Control Valve
Product Model: ZXGQ (X) Product Features: ZJFF (H) Pneumatic Thin Film Three way Split (Close) Flow Regulating Valve
Product details
ZJSF(H)The pneumatic thin film three-way flow control valve adopts a dual valve core up and down guiding structure, equipped with pneumatic or electric actuators. The valve body is a three-way structure, with one inlet and two outlets (diversion type) and two inlets and one outlet (merging type), so as to achieve fluid mixing heating or cooling, or uneven fluid diversion, meeting the requirements of different industries and mines. The valve body has the advantages of compact structure, light weight, sensitive action, low pressure drop loss, large valve capacity, precise flow characteristics, and easy maintenance. It can be used under various working conditions, especially for temperature control systems of heat exchangers in the petroleum industry and automation control systems in other industries. This series of products includes various types such as room temperature type, high temperature type, low temperature type, adjustable cutting type, and corrugated pipe sealing type. The nominal pressure rating of the product includesPN1.6、4.0Multiple specifications are available for selection. This series of regulating valves uses fluid temperature-150-560Multiple grades within the temperature range of ℃; Leakage level neon is divided intoIVLevelVLevelVIGrade; Traffic characteristics include straight lines and percentages. Multiple specifications are available for selection. This series of regulating valves adopts a modular design, which can be combined in different ways and equipped with various accessories.
