TYFZ butterfly valve type pressure regulating valve groupDetailed product description：

summary:
The TYFZ type gas pressure regulating valve group is suitable for blast furnace systems in ironworks, ensuring stable top pressure within a certain range by regulating the flow rate of gas medium. Installed on the clean gas pipeline after the dust removal device (wet dust removal or dry dust removal). It is also applicable to other gas medium pipeline systems that require flow rate and pressure regulation to maintain stable production.

Characteristics and Applications:
The TYFZ type gas pressure regulating group consists of ZAJW-1 type automatic regulating butterfly valve and normal pipe. In use, one ZAJW-1 automatic regulating butterfly valve is generally controlled automatically through a DDZ electric unit combination instrument, while the other two (or three) ZAJUW-1 automatic regulating butterfly valves are roughly adjusted by electric actuators equipped with valves through manual operators on the instrument panel to achieve pressure regulation of system flow. TYFZ gas regulating valve group is suitable for blast furnace systems and other flow control systems. Pressure regulation is a system that maintains stable production. When installing this valve group on a horizontal pipeline, there is no directional requirement, but the regular pipe should be placed below the valve group to ensure the discharge of condensed water when the system temperature drops. When installing on a vertical pipeline, the working position of the electric actuator should be considered.
