Brass Union Filter Ball Valve

Yunnl brass union filter ball valve is an all-in-one fluid control fitting designed for residential HVAC, commercial water supply and light industrial circulation systems. This integrated component combines inline filtration and shut-off ball valve functions to simplify pipeline layout and reduce accessory installation quantity.

The valve body is forged from eco-friendly HPb59-1 brass, which meets global drinking water contact standards and adapts to water, light oil and non-corrosive gas media. Every valve undergoes precision CNC machining, achieving a surface roughness of Ra≤0.8μm. Smooth inner surfaces effectively cut fluid flow resistance and deliver stable long-term sealing performance.

Available in DN15 to DN32 standard sizes, two optional configurations are supplied: pressure gauge version for real-time pipeline pressure monitoring, and PPR union connector model for plastic heating pipe quick connection.

■ Efficient 304 Stainless Steel Filtration & Quick Service

• Removable 304 stainless steel filter screen, mesh density customizable from 80 mesh to 180 mesh for different fluid impurity levels.
• Quick-release modular structure allows full screen cleaning without extra tools, cutting routine maintenance time by 75% vs traditional Y strainers.
• Optimized internal hydrodynamic flow channels build passive self-flushing performance, lowering manual cleaning frequency for long-term HVAC operation.

■ Stable Zero-Leak Sealing & Wide Pressure Adaptability

• Composite PTFE + graphite sealing ring features automatic pressure compensation, adapting to fluctuating working pressure from 0.2 MPa to 2.5 MPa.
• Metal hard sealing ball core maintains tight shut-off within 5℃–90℃ medium temperature, fully complying with international valve sealing class A standards.
• Dual-layer sealing structure adds safety buffer for sudden pipeline pressure surges.

■ Long Service Life & Anti-Corrosion Construction

• Passed 200,000 open-close cycle durability test with zero sealing surface abrasion.
• Complete 72-hour neutral salt spray test without rusting on brass body and stainless steel screen.
• Anti-seize nano coating on all threaded connections prevents thread jamming after years of hot & cold water cycling.

■ Energy Saving

• Full bore ball core design minimizes flow resistance, lowering circulating pump energy consumption by 15%.
• Built-in pressure relief safety structure avoids pipeline damage under abnormal overpressure.

■ Civil & HVAC Heating Systems

• Central heating floor loop, fan coil unit and heat pump circulation water filtration.
• Whole-house domestic cold/hot water pipelines, prevent faucet, shower and water heater clogging caused by sediment and rust.
• Small commercial office, café and hotel water supply main pipeline protection.

■ Light Industrial Circulation

• Food processing and pharmaceutical low-corrosion fluid filtration.
• Factory cooling tower, water chiller circulating water impurity interception, extend pump and heat exchanger service life.

■ Special Gas Pipeline Applications

• Non-corrosive general gas pipeline shut-off and pre-filtration; explosion-proof customized models available for industrial gas projects.

Unlike split separate ball valves and Y strainers that require multiple pipe fittings for installation, this Yunnl integrated filter ball valve combines shut-off and filtration in one single unit. It shortens pipeline layout, reduces potential leakage points and cuts overall project installation costs for HVAC contractors and plumbing wholesalers.

The tool-free quick disassembly design drastically reduces maintenance downtime for property management companies and industrial plant operators. Instead of removing the whole valve from pipelines to clean impurities, users only detach the bottom filter cartridge within 15 seconds for flushing, greatly cutting labor and system shutdown costs.

Supported by global water safety certifications including NSF 61, CE and WRAS, this brass filter ball valve meets plumbing engineering standards for most overseas markets. It balances long-term durability, low maintenance cost and universal media adaptability, becoming a preferred integrated pipeline fitting for heating, domestic water and light industrial fluid control projects.

1. Install the valve vertically or horizontally on the main inlet pipeline of heating or water supply systems.

2. Align the arrow flow mark on the valve body with actual fluid direction to avoid reverse flow.

3. Select matching accessories: pressure gauge version for real-time pipeline pressure monitoring; PPR union model for plastic heating pipe connection.

4. Clean the filter screen every 1–3 months according to local water impurity concentration to maintain stable flow rate.
