DOPAG regulator is used to reduce the material input pressure to the required operating pressure. In addition to accurately regulating material pressure, the regulating valve also counteracts pressure fluctuations caused by the interaction of the plunger pump. This pressure fluctuation reduces the pressure for a short period of time and causes the material flow rate to drop slightly. If the amount of glue (oil) required is small, this may affect the quality of the product, especially the application of the amount of glue (oil) required. Depai pressure regulating valve can be used to handle the viscosity of 5000 to 500000mPa s materials, there are two different construction:
Plunger type pressure regulating valve
This type of pressure regulating valve is suitable for handling grease, lubricating oil, single component and multi-component silicone. The inner space of the valve is sealed by a spring seal ring.
Diaphragm pressure regulating valve
Most of these valves are suitable for active, humidity-sensitive materials. Because ball valves and seats are made of tungsten alloy, they are also suitable for wear resistant materials such as epoxy, polyurethane, and other materials. The inner space of the valve is sealed by a spring seal ring.
