Axial Flow Check Valve Advantages

In addition to the general function of a check valve, the axial flow check valve offers several key advantages:

Low Noise and Impact: Utilizes a spring mechanism to reduce noise and impact.
Axial Flow Structure: Ensures low fluid resistance, high flow capacity, and a compact design.
Ideal for Pump Outlets: Perfect for use in pipeline systems transporting oil, gas, and water, making it an excellent choice for non-return applications.

Product Features

» One-Piece Body: Lightweight, strong, and easy to maintain.
» Spring-Activated Thrust Force: Ensures the valve stays closed even without the force of the medium.
» Versatile Sealing Carrier: Allows installation in any orientation, with the disc perfectly sealing against the seat.
» Axial Flow Structure: Provides minimal pressure loss, stable flow, and prevents cavitation erosion. The disc returns to the sealing position using spring force and sub-pressure from the medium flow, preventing direct impact from the medium onto the back of the disc. This results in low noise operation.
» Disc Carrier and Pin Surface Treatment: Specially designed to eliminate valve sticking, ensuring smooth operation. The disc closes evenly, avoiding common issues where the disc does not stay centered due to gravity. This ensures a reliable, lasting seal.
» Sealing Position Assurance: The spring thrust force slightly exceeds the combined force of the disc's gravity and friction between the disc and sealing ring. This design ensures the disc returns to its sealing position even at low pressures, regardless of installation orientation, protecting pump operation.
