Product Overview

Self-actuated regulating valve is a device that integrates detection, transmission, control and execution into a single unit.They differ significantly from regular control valves due to their unique characteristic of operating automatically using the energy of the controlled medium without requiring external energy sources such as electricity or gas.

Classification Of Self-operated pressure regulating valves :
1.ZPL610(ZZYP, ZZYM) type: self-operated pressure regulating valve 
2.ZPL620(ZZVP, ZZVM) type: self-operated micro-pressure regulating valve 
3.ZPL630(ZZYVP-BII) type: With pressure controller regulating valve (nitrogen seal device)
4.ZFQ type: explosion-proof fire-resistance breathing valve

Application And Characteristics Of ZPL610

The ZPL610 Type self-actuated pressure regulating valve is operates autonomously, using the energy of the controlled medium without relying on external power sources. Its key advantage lies in its ability to function effectively in environments devoid of electricity and compressed air, while simultaneously conserving energy. Furthermore, the pressure setting range can be flexibly adjusted within a specified request.

Selection Guide Of ZPL610

According to internal structures
1.Single-seat structure   
2.With Steel Bushing structure
3.Double-seat structure
According to Bonnet Type

1.Ordinary type: used in general situations

2.Long-neck type: need wide range of pressure regulation

3.With cooling disc: While the medium temperature upto 350ºC

According to the type of Pneumatic Actuator

1.Assembled with Standard Diaphragm (or reinforced diaphragm)

2. Assembled with Piston
3. Assembled with Metal diaphragm (OCr18Ni9)

The ZPL610 self-actuated pressure regulating valve offers flexibility selection based on working conditions such as pressure differential, temperature, and medium state, as well as leakage requirements. It features a fast-open flow characteristic, ensuring quick response and high regulation accuracy with an error margin of less then 10%. Compared to other types,ZPL610 valve occupies less space and is easily adjustable, making it widely used in various industries including petroleum, chemical, electric power, metallurgy, food processing, textiles manufacturing, mechanical engineering, and civilian infrastructure for gas, liquid or steam pressure reduce and stabilization (for post-valve regulation), or pre-valve regulation for pressure relief and stabilization.
