22mm Brass Gate Valve Full Flow 20 Bar PTFE Sealed

22mm Brass Gate Valve Full Flow 20 Bar PTFE Sealed

For applications requiring reliable fluid shut-off in pipeline systems, the 22mm brass gate valve is a common and effective choice. Its design allows for full-open or full-close operation, ensuring minimal resistance to fluid flow.

Common Materials and Specifications of 22mm Brass Gate Valve

The valve body is mainly made of brass, a material with excellent machinability and corrosion resistance, suitable for water and various neutral fluids. The standard specification features a nominal diameter of DN22 (equivalent to 3/4 inch). The valve stem is typically crafted from stainless steel to enhance wear and corrosion resistance.

Connection and Actuation Methods of 22mm Brass Gate Valve

This type of valve generally adopts threaded connection for easy installation. Common interface types include British Standard Pipe Taper (BSPT) or British Standard Pipe Parallel (BSPP) internal threads, ensuring a tight fit with pipeline systems. Manual operation is the primary actuation method, via rotating a handwheel or lockshield handle, to meet daily on-off requirements.

Pressure Rating and Performance Features of 22mm Brass Gate Valve

The maximum working pressure of this specification of brass gate valve is usually 20 bar. Its internal gate plate is designed to retract into the valve body cavity when fully open, forming a straight-through flow passage. This effectively reduces pressure loss and achieves near-full flow capacity. Elastic materials such as PTFE (polytetrafluoroethylene) are used as sealing gaskets to enhance sealing performance and extend service life.

The connection of multi-turn valve actuators complies with GB/T 12222 standard.

What systems is this 22mm brass gate valve mainly suitable for?

This valve is primarily designed for cold and hot water pipeline systems in buildings and general water supply systems. Its brass valve body and PTFE sealing material are well-suited for water media, and the 20 bar pressure rating is sufficient to meet the water pressure requirements of multi-story buildings. It is not recommended for corrosive chemical fluids or extreme high-temperature environments.

To ensure applicability in the global market, the production and testing of this 22mm brass gate valve incorporate a number of key international standards. Its design and materials meet the relevant requirements of AWWA C509 (for water supply systems) and ISO 15761 (for the oil and gas industry). Each batch of products undergoes rigorous shell strength testing and sealing performance testing in accordance with EN 12266-2 or equivalent standards, with complete test reports provided. This is a mandatory quality verification process before the valves leave the factory.
