Axial Seals | V-Rings – VL VS VA
This Seals are normally of 3 type such as
-
V-Rings – VL
-
Axial Seals -VS
-
Rings -VA
It protect from grease, oil, mud, water, dust and other media. It is used in many machine starting from low load up to heavy-duty areas of application.
Axial Seals
Axial Seals are a type of seal designed to prevent leakage along a shaft or rod moving in a reciprocating (back-and-forth) motion. V-rings, specifically, are a popular and versatile type of axial seal known for their simplicity and effectiveness.
However, within the Axial Seals V-Rings family, there are two main variations: VL and VA. Here’s a breakdown of their key differences:
VL V-Ring:
- Sealing Lip: The VL V-ring features a single, sharp sealing lip that provides a strong initial seal against the mating surface.
- Applications: Suitable for moderate pressure applications where space limitations may exist. They are commonly used in light to medium-duty hydraulic and pneumatic cylinders.
- Advantages: Simple design, low cost, effective initial sealing.
- Disadvantages: May experience higher wear due to the concentrated contact area of the single lip. Not ideal for high-pressure applications where wear resistance is critical.
VA V-Ring:
- Sealing Lip: The VA V-ring features a wider, double-angled sealing lip. This design creates a more distributed sealing force and increased contact area.
- Applications: Ideal for applications with higher pressures and where wear resistance is a concern. Commonly used in pneumatic and hydraulic systems with demanding operating conditions.
- Advantages: Offers better wear resistance and sealing performance compared to VL rings at higher pressures.
- Disadvantages: Slightly higher cost and bulkier profile compared to VL rings.
Choosing Between VL and VA V-Rings:
The best choice between VL and VA V-rings depends on your specific application. Here’s a quick guide:
- For moderate pressure applications and cost-effectiveness, choose a VL V-ring.
- For higher pressure applications and situations where wear resistance is crucial, choose a VA V-ring.
Additional Considerations:
- Material: Both VL and VA V-rings come in various materials like Nitrile rubber, Polyurethane (PU), and Fluorocarbon (FKM) to suit different operating temperatures, fluids, and pressure requirements.
- Installation: Proper installation is crucial for optimal sealing performance. Ensure the V-ring is installed with the correct orientation and lip facing the pressure source.
