800X Pressure Differential Valve

Specifications

Taian provides high quality 800X Pressure Differential Valve,You can rest assured to buy it from our factory.This Differential Valve is superior to other balance valves and does not require other actuating mechanisms. 800X Pressure Differential Valve completely relies on the pressure difference of the medium itself to achieve system balance, saving energy and installation space.

Working principle

When the pressure difference between the inlet and outlet of the main valve changes, the pressure difference at both ends of the pilot valve changes, and the opening of the pilot valve changes. When the pressure difference is large, the opening of the pilot valve is large, the water discharge in the control room increases, the pressure in the control room of the main valve decreases, the opening of the main valve increases, and the pressure difference between the inlet and outlet of the main valve becomes smaller. On the contrary, the pressure difference between the inlet and outlet of the main valve becomes smaller, the inlet valve opening becomes smaller, the pressure of the main valve control room rises, and the main valve opening decreases and the main valve pressure difference increases. This negative feedback effect makes the pressure difference between the inlet and outlet of the main valve stable at the set value. Set the needle valve opening and pilot valve spring pressure to set the pressure difference between the main valve inlet and outlet.

Installation and Maintenance

Installation location: 800X Pressure Differential Valve is usually installed between the water supply and return pipes of the air conditioning system.

Maintenance: Due to its self-controlled characteristics, maintenance is relatively simple.

The 800X differential pressure bypass balance valve is a highly efficient, energy-saving and easy-to-maintain valve, suitable for a variety of applications that require precise differential pressure control
