Overview of ZZYP type self operated pressure regulating valve:

ZZYP type self operated pressure regulating valve is an energy-saving control device that does not require external driving energy, relies on the pressure of the regulated medium itself as the power source and its pressure changes, and automatically adjusts according to the predetermined set value. It integrates detection, control, and execution of many functions into one valve, forming an independent instrument control system. This product has the advantages of no need for external energy, simple structure, easy use, and low maintenance workload. It is particularly suitable for urban heating, heating, and situations where there is no external power or gas supply and steam pressure needs to be controlled. According to foreign reports, the use of this product in urban heating and heating systems has significantly increased energy efficiency by 30% -40% compared to before.

Characteristics of ZZYP type self operated pressure regulating valve:

An energy-saving self-control system that does not require external driving energy, has low equipment costs, and is suitable for explosive environments; Simple structure and low maintenance workload; The set point is adjustable and has a wide range, making it easy for users to continuously adjust within the set range; Diaphragm type execution machinery has higher detection accuracy and more sensitive action than cylinder type mechanisms; The valve adopts a pressure balance mechanism, which makes the regulating valve responsive, precise in control, and allows for a large pressure difference.
