Back Pressure Valves Relief Valves for Low-Pressure Metering Pumps
Accurately metered
Back pressure valves are designed for different applications. Please refer to the relevant notes for the different designs.
Relief valves are used in the bypass to protect pumps, pipes and fittings from overpressure in the event of incorrect operation or blockages. In the event of a malfunction, the pump pumps back into the storage tank.
The benefits for you
- Protects against overpressure
- Priming aid
- Relieves the pressure line
- Increases dosing precision

Multifunctional Valve Type MFV-DK, PVDF
Back pressure valve/relief valve for fitting directly on the pump\’s dosing head with the functions:
- Back pressure valve, opening pressure approx. 1.5 bar with free outlet or priming pressure at the suction end (black rotary dial)
- Relief valve, opening pressure approx. 6, 10 or 16 bar (red rotary dial)
- Priming aid for pending back pressure, no need to release discharge line
- Discharge line relief, e.g. prior to service work
The multifunctional valve is operated by free-moving rotary dials that automatically return to their original position when released by the operator. This means operation is possible even when access is difficult. The multifunctional valve is made of PVDF and can be used to meter almost any chemical.
Caution: Back pressure valves are not absolutely leak-tight shut-off devices! It is essential that you observe the installation notes in the operating instructions!
Caution: The bypass line should always be connected.

I had read other reviews which reported a bad chemical smell, and I figured it can\'t be that bad or it will fade or I\'ll clean it real well and that\'ll get rid of it.
I purchased the bed to fit the back of my ford explorer. It fits perfectly and is well made. Great purchase.
