Product Introduction

This product, developed by our engineering and technical personnel through the introduction of new technologies as well as improvements in manufacturing processes and structures, has reached the advanced level of international similar products. The valve body adopts a full-channel streamlined design, featuring low fluid resistance and large flow rate. It uses hydraulic operation in terms of transmission mode, that is, the water pressure in the pipeline is utilized to automatically control the vertical movement of the main valve disc and adjust the opening of the main valve port. The main valve is installed in the pipeline for controlling flow in water supply and distribution pipelines. By presetting and adjusting the pilot regulating valve and a fixed flow rate of the pilot valve on the upper part of the valve, the flow rate through the main valve can be kept constant without being affected even if the pressure upstream of the main valve changes. In a word, this product is an ideal choice for domestic water supply, fire protection systems and industrial water supply systems.

The valve body adopts a full channel streamline design, with low fluid resistance and high flow rate. Hydraulic operation is adopted in the transmission mode, which uses the water pressure in the pipeline to automatically operate the up and down movement of the main valve disc and control the opening of the main valve port. The main valve is installed in the pipeline of the water supply and distribution pipeline to control the flow rate. You can first set a fixed flow rate for the upper guide regulating valve and the guide valve to keep the flow through the main valve constant, even if the pressure upstream of the main valve changes, it will not affect it.

The valve consists of a main valve, pilot valve, pilot regulating valve, needle valve, ball valve, micro-filter, pressure gauge, etc. Since the pilot valve, needle valve, pressure gauge and other components are connected to the main valve via conduits, they are collectively referred to as the conduit control system. It can be divided into diaphragm type and piston type according to the requirements of different pipe diameters.
