Introduction of ZJSF/H pneumatic film three-way regulating valve: The ZJSF(H) pneumatic film three-way split (combined) flow regulating valve adopts a double valve core up and down guide structure, equipped with a pneumatic actuator or an electric actuator. The valve body is a three-way structure, that is, one inlet and two outlets (split type). Two inlets and one outlet (combined flow type), so as to achieve fluid mixing to raise or lower temperature, or fluid unequal diversion, to meet the requirements of different industries and mines.

The valve body has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics and convenient maintenance. It can be used in a variety of different working conditions, and is especially suitable for the temperature control system of the oil industry heat exchanger and other automation control systems in various industries. This series of products has many types such as normal temperature type, high temperature type, low temperature type, adjustable cut-off type, and bellows sealed type. The nominal pressure grade of the product is available in PN1.6 and 4.0 specifications. This series of regulating valves adopts a variety of grades within the range of fluid temperature -150-560℃; leakage grade neon is divided into grade IV, grade V, and grade VI; flow characteristics are linear and percentage. A variety of specifications are available. This series of regulating valves adopts modular design, which can adopt different combinations and be equipped with various accessories.
