RPI VPV057 Check Valve (1/4" In-Line)

Yes, this valve is explicitly designed for the Air Techniques VacStar 2 dental vacuum unit. It serves as a direct replacement for OEM Part #56056, ensuring seamless integration into your manifold assembly.

Absolutely. This unit is constructed with a robust brass body paired with a durable Buna-N (Nitrile) seal. These high-quality materials are selected to withstand the rigors of dental vacuum system environments, ensuring consistent, dependable performance over time.

Yes, it is engineered with a specific cracking pressure of 1.0 PSI. This precision is critical for maintaining the correct vacuum system functionality and preventing backflow in your manifold assembly.

Installation is designed to be efficient. The valve features standardized, professional-grade plumbing interfaces:

• Inlet: 1/4” Female Pipe Thread (FPT)
• Outlet: 1/4” Male Pipe Thread (MPT)

These dimensions allow for a straightforward, direct in-line connection into your existing setup.

Yes, every RPI VPV057 check valve is supplied Factory New. This guarantees that you are receiving an unused, precision-engineered part that is ready for immediate installation and optimal operation in your equipment.

This check valve is a vital component for your vacuum system’s health. It acts as a one-way gate that prevents backflow, ensuring that air flows in the correct direction within the VacStar 2 manifold assembly, which is essential for maintaining consistent vacuum power.

Yes, this RPI product directly corresponds to OEM Part #56056. It is engineered to meet or exceed the performance specifications required by the original manufacturer, providing a high-quality, reliable alternative for your maintenance needs.

The Buna-N (Nitrile) seal is specifically chosen for its excellent mechanical properties and resistance to wear. It provides a tight, reliable seal that is crucial for maintaining the precise 1.0 PSI pressure differential required for your vacuum unit’s optimal efficiency.

Yes, the VPV057 is specifically intended for integration into manifold assemblies. Its compact, in-line form factor is optimized for these tight spaces where precise airflow control is necessary.

It is highly critical. The 1.0 PSI cracking pressure is the exact performance specification required for the Air Techniques VacStar 2 to function correctly. Using a valve with the wrong pressure rating could negatively impact your vacuum system’s suction power and overall efficiency.
