Overview of ZZYP-16BII self-operated pressure regulating valve with pilot: The pressure regulating valve does not require external energy, and uses the energy of the regulated medium as the power source. A pressure stabilizing device that automatically controls the flow of the valve medium and keeps the pressure behind the valve constant. It has been widely used in the production and transportation of natural gas with continuous gas supply, city gas and industrial production sectors such as metallurgy, petroleum and chemical industry. The valve features: high control accuracy, about twice as high as the general ZZY type direct-operated pressure regulating valve.

10ZZYP-16BII self-operated pressure regulating valve with pilot
Large adjustment pressure difference ratio (such as 0.8MPa before the valve, 0.001MPA after the valve) is especially suitable for low pressure gas control.
The pressure setting is realized on the pilot, so it is convenient, fast, labor-saving and time-saving, and can be set continuously in the running state.
