Brass Valves: Types, Specifications, and Selection Guide for Water & Gas Systems
Brass Valves: Types, Specifications, and Selection Guide for Water & Gas Systems
Brass valves are essential components in fluid control systems across construction, HVAC, compressed air, water treatment, and industrial machinery. Understanding the different types, their materials, pressure ratings, and intended applications is the first step in selecting the right valve for your project. Zhejiang BoZheng Copper Industry CO., LTD. (Bozheng Valve), established in 1998 in Yuhuan City—known as the "Valve Capital of China"—is a manufacturer of brass and stainless steel valves with a 6,700 m² facility, 180 employees, and an annual output of 3,200,000 units.
The Challenge: Choosing the Right Brass Valve
With multiple valve types—ball, gate, globe, check, pressure reducing, and strainer—each with different configurations and materials, procurement decisions can be overwhelming. Factors such as working medium (water or gas), pressure (1.6 MPa), end connections (threaded or flanged), and industry-specific requirements must be matched precisely.
Industry Background
Brass valves are widely used in construction and building (HVAC/plumbing), compressed air systems, low-pressure steam and boilers, oil and fuel systems, swimming pools and water treatment, and industrial machinery (mold cooling/hydraulics). Bozheng Valve, with over 20 years of experience, supplies these industries globally, with exports to EU, USA, SEA, Central Asia, and Africa.

It uses brass HPb59-1, HPb57-3, CW617N, and C83600. Normal pressure 1.6 MPa, media water and gas. Suitable for construction, compressed air, low-pressure steam, oil and fuel, swimming pools, and industrial machinery.
6. Brass Strainer (Model SY11X-16T)
The brass strainer model SY11X-16T is a blow-down/flush type with a perforated screen and threaded ends. It is made of brass HPb59-1, HPb57-3, CW617N, and C83600. Normal pressure 1.6 MPa, media water and gas. Intended for construction, compressed air, low-pressure steam, oil and fuel, swimming pools, and industrial machinery.
Step-by-Step Selection Guide
- Identify the working medium and pressure: All Bozheng brass valves are rated for 1.6 MPa and handle water and gas. Confirm your system pressure and media compatibility.
- Choose the end connection: Options include threaded ends (standard) and flanged ends (available for ball valves).
- Determine the control function: Use ball valves for quick on/off, gate valves for isolation, globe valves for throttling, check valves for backflow prevention, pressure reducing valves for downstream regulation, and strainers for debris filtration.
- Consider material options: Valves are offered in HPb59-1, HPb57-3, CW617N, and C83600 brass. CW617N is also used in lockable lever handle versions.
- Verify manufacturer capability: Bozheng Valve operates a 6,700 m² factory with 25 R&D engineers and an annual capacity of 3.2 million units, ensuring consistent quality and supply.
