Design Standard: ANSI B16.34
Threaded End: NPT / BSPT / RC / G
Inspection and testing: API598

Product Advantages

1. The threaded vertical check valve has a simple and compact structure, takes up small space, and is suitable for occasions with limited installation space.

2. The clack of threaded vertical check valve is flexible to open and close, easy to operate, and does not require an additional power.

3. The threaded connection has good sealing performance. Through advanced sealing design and high-quality sealing materials, it can effectively prevent the medium from leaking from the connecting parts and ensure the normal operation of the pipeline system.

4. Threaded vertical check valves mainly include internal threaded vertical check valves, spiral check valves, and stainless steel threaded check valves.

• Threaded vertical check valves are widely used in various industrial fields, especially in pipeline systems in petroleum, chemical, electric power, metallurgy and other industries. It is suitable for a variety of media such as liquid and gas, and is often used at the outlet of the pump to prevent the backflow of the medium from damage, or is installed at a high place to prevent the high-pressure water hammer from damaging the pipeline and equipment when the system is shut down‌ 

• The threaded connection method makes the installation relatively simple and does not require complicated tools and equipment. Simply thread the valve and pipeline together, greatly reducing installation difficulty.‌
