How Ball Type Non-Return Valve Screwed End Works
Inside each ball type non-return valve screwed end, a spherical ball acts as the primary sealing element. When fluid flows in the forward direction, line pressure pushes the ball off its seat, allowing unrestricted flow. The moment flow reverses or pressure drops, the ball returns to its seat and seals the passage, preventing any backflow.
The screwed end connection — available in BSP and NPT threading — ensures easy installation, a secure fit, and a reliable seal without the need for flanges or welding. This makes the valve especially suitable for compact pipelines and maintenance-friendly installations.

Frequently Asked Questions
Answers to common questions about ball type non-return valve screwed end, materials, sizing and selection.
A ball type non-return valve screwed end is a check valve that uses a spherical ball as the sealing element and threaded connections for installation. It allows fluid to flow in one direction only and automatically blocks reverse flow when pressure drops or flow stops.
When forward flow pressure pushes the ball away from its seat, fluid passes through freely. When flow reverses or stops, the ball returns to its seat under gravity or spring force, sealing the passage and preventing backflow without any manual operation.
Our ball type non-return valve screwed end handles operating pressures up to 40 bar, making it suitable for both light-duty water systems and demanding industrial applications.
We manufacture ball type non-return valve screwed end in sizes ranging from 15 mm to 100 mm to suit various pipeline diameters across industrial and commercial applications.
The valve body is available in cast iron, stainless steel, and brass. Sealing materials include PTFE, NBR, and Viton — selected based on the media, temperature, and operating conditions.
Screwed end non-return valves use threaded connections for quick installation without flanges or additional fasteners, making them ideal for compact piping. Flanged end valves are better suited for larger pipelines and higher pressure systems where bolted connections are required.
These valves are widely used in water supply systems, oil and gas pipelines, chemical processing plants, HVAC systems, pumping stations, and general industrial fluid transfer lines.
Yes. Depending on the sealing material selected, our ball type non-return valve screwed end supports temperatures up to 200°C, with Viton and PTFE seats recommended for high-temperature media.
Yes. Concorde Valves & Automations provides customized configurations based on size, body material, pressure class, sealing material, and thread standard (BSP or NPT) to meet specific project requirements.
