Stainless Steel Axial Flow Check Valve

FVF Stainless Steel Axial Flow Check Valve

Application

Except of the general function of check valve, the FVF axial flow check valve has the advantagesof small noise and lower impact with the using of a spring. With the axial flowing structure, the valve has characteristic of small fluid resistance, great flow capacity, and small outer dimension which makes this valve a wonderful choice using on the outlet of pump in pipeline system transporting oil and gas. It is used on the pipeline transporting oil, gas, water and etc. For non- return demanding condition.

Product Features

• 1. One-piece body, small weight, good strength, and easy maintenance.
• 2. The thrust force of spring enables the valve stayed in closed position even without the force of medium.
• 3. Wonderful sealing carrier makes the valve able to be installed at any direction, and the disc can tough the seat sealing perfectly.
• 4. Axial flow structure and accurate flowing passage enables little pressure loss, stable medium flowing, and non cavitation erosion. The disc returns to the sealing position with the force of spring and sub-pressure caused by medium flowing. So there is No. Direct impact of the medium onto the back side of the disc. Axial flow check valve is a low-noise type.
• 5. The special structure and surface treatment of the disc carrier and pin eliminates the phenomenon of valve sticking. It can close and open evenly to avoid the common defects of disc can not stay in the center of sealing position because of the gravity of disc. So the valve has wonderful and lasting sealing effect.
• 6. In closed position, and accurate design makes the thrust force of spring is a little bigger than the force of disc's gravity plus the friction force between disc and sealing ring. And the disc can return to its sealing position under low pressure despite of any installation position so as to protect the operation of pump.
