Proportional pressure regulator VPPL

Product Description
The Festo VPPL is a proportional pressure regulator specially developed for higher pressures from 10 to 40 bar, featuring a directly actuated piston design . Available as an individual device with threaded connections in three variants—flanged valve, flanged valve with external pilot air supply, or in-line valve—this regulator is ideal for demanding high-pressure applications such as PET bottle stretch blow moulding in the food and beverage industry or tyre and brake test benches in the automotive sector .

Key Features & Advantages:

• Directly Actuated Piston Regulator for High-Pressure Applications: Specially developed for higher pressures from 10 to 40 bar, with a maximum operating pressure capability up to 50 bar, ensuring reliable performance in demanding industrial environments .

• Direct Control with Mechanical Spring Reset: Directly controlled piston regulator design delivers precise pressure regulation with a mechanical spring reset mechanism, providing a safe output pressure drop to 0 bar if the power supply cable is interrupted .

• Three Mounting Variants for Flexible Integration: Available as a flanged valve, flanged valve with external pilot air supply, or in-line valve with threaded connections (G1/4), accommodating diverse installation requirements .

• Analogue Setpoint Input with LED Display: Features 4–20 mA analogue input signal with LED display, housed in an anodised wrought aluminium alloy body for industrial durability .

• Soft Sealing with IP65 Protection: Soft sealing principle ensures reliable operation, with IP65 protection class suitable for demanding industrial environments; supports compressed air and inert gas media (oiled operation not possible) .
