Description & Overview
The ball non return valve is a one-way valve that relies on the pressure of the medium itself and the gravity of the sphere to achieve automatic opening and closing. The core function of check ball valve is to prevent fluid backflow and protect the safety of pipeline systems and equipment. It mainly consists of a valve body, a spherical valve disc, a valve seat, a guiding mechanism, and an end cap. The valve body is mostly made of cast iron, cast steel, stainless steel, and other materials. The valve disc can be made of rubber coated steel balls, PTFE balls, etc., to meet different working conditions.
Key Advantages
The valve seat of one way valve ball type is often made of soft sealing materials such as rubber and PTFE, which are tightly attached to the spherical valve disc. The sealing surface is smooth and wear-resistant, which can effectively prevent medium leakage and maintain good sealing effect even under low pressure conditions.
The non return valve disc will roll under the push of fluid, and during the rolling process, it can take away impurities and particles on the sealing surface, achieving self-cleaning function and avoiding blockage and jamming.
The core components only include spheres, valve seats, etc., which are easy to disassemble and repair without the need for complex professional tools. The daily maintenance cost is low, which can reduce downtime for maintenance and improve pipeline operation efficiency.

Frequently Asked Questions (FAQ)
The working temperature range for this ball check valve is between 0°C and 80°C (0°C < T < 80°C).
This valve is manufactured in compliance with BS, API, DIN, and JIS standards.
The valve disc rolls automatically under the push of fluid motion. As it rolls, it removes impurities and debris from the sealing surface, preventing blockages and maintaining clean operation.
The valve body is available in Ductile Iron, Cast Steel, and Stainless Steel. Sealing components are crafted from high-grade EPDM or NBR rubber, with options for rubber-coated steel or PTFE balls.
No, the valve operates completely automatically based on the fluid pressure of the medium and the natural gravity of the internal sphere.
