Stainless Steel Back Pressure Check Valve

186 Series Back Pressure Valve

Product Description

It is installed in the positive pressure discharge pipeline of the Metering Pump or diaphragm pump to avoid the occurrence of siphonage and to eliminate changes in the dosing volume due to pressure fluctuations at the dosing point, thus ensuring the dosing accuracy of the pump. Remove the protective cap from the adjusting screw on site, turn the adjusting screw and adjust to the required pressure with the aid of a pressure gauge in the pipeline. The back pressure can be set  in the range of 0-0.6Mpa by adjusting screw.When used in conjunction with a pulsation damper, it can reduce water hammer damage to the system, maintain a constant pressure from the pump outlet to the back pressure valve and keep the system flow rate constant.

Features

· Provide pressure gauges for the lines at both ends of the back pressure valve;

·Avoid siphoning and eliminates dosing variations caused by pressure fluctuations at the dosing point;

· When used in conjunction with a pulsation damper, it can reduce water hammer damage to the system

to achieve superior low vibration regulation;

·Reduce peaks in flow rate fluctuations and protect piping systems from pressure fluctuations;

· The diaphragm is made of an advanced PTFE+rubber compound, which is suitable for almost all

corrosive fluid and provides a reliable and leak-free seal.
