PPR Single Union Filter Ball Valve

• Introduction

Yunnl PPR single‑union Y‑type filter ball valve is an integrated brass fitting that combines ball‑valve shut‑off function and Y‑strainer filtration. One end adopts PPR single union connection for fast assembly with PPR heating pipelines, the other end is male threaded connection. Equipped with built‑in stainless steel filter screen, this component traps sediment, scale and pipe debris inside water circuits. The bottom drain plug allows quick flushing without full disassembly. With a blue 90‑degree lever handle for fast open‑and‑close control, this valve is widely installed at the inlet of heating manifolds to protect downstream underfloor heating circuits and household plumbing equipment from particle contamination.

• Core Positioning

This all‑in‑one fitting replaces separate ball valve + Y‑strainer two‑piece setup. It saves installation space, reduces potential leakage points, and simplifies piping layout for residential heating and light‑commercial water‑supply projects.

• Dual‑Function Integrated Design

Combines shut‑off ball valve and Y‑shape strainer into one unit. One‑piece structure removes requirement to install separate valve and filter, cutting installation time and lowering risk of joint leakage.

• Convenient PPR Single‑Union Connection

The PPR union joint enables simple, reliable connection with PPR hot‑water pipes. The union structure supports easy disassembly for maintenance without cutting pipelines.

• Built‑in Filter Screen with Bottom Drain Port

Stainless‑steel filter mesh captures sand, rust particles and pipeline debris. The bottom drain plug supports quick flushing and cleaning; no need to take down the whole valve from piping for routine maintenance.

• Reliable Brass Construction & Tight Sealing

Forged brass valve body delivers outstanding corrosion resistance for hot‑water circulating systems. PTFE ball seat plus NBR stem O‑rings guarantee zero‑leak shut‑off performance for long‑term continuous operation.

• Simple Manual On‑Off Operation

Blue metal lever handle realizes 90‑degree open / close switch. Note: this ball valve is for full open / full close shut‑off service, not designed for flow throttling.

Operation & Filtration Mechanism

When fluid flows through the Y‑shaped cavity, solid impurities are intercepted by the internal stainless‑steel strainer screen. Clean water passes toward downstream pipelines. For routine maintenance: open the bottom drain plug to flush trapped sediment directly. The ball‑valve function can cut off water flow so users can clean or replace filter screen without shutting down the whole building water main. The PPR single‑union joint permits full removal of internal filter assembly when heavy fouling occurs.

• Residential Underfloor Heating & Radiator Systems

Installed at inlet port of water manifolds. Blocks pipe scale and debris, protects manifold components and floor‑heating loops from particle damage.

• Household Domestic Water Supply

Main pipeline pre‑filtration for residential buildings, intercept construction debris and sediment inside new plumbing installations.

• Light‑Commercial HVAC & Heating Projects

Small commercial heating circuits, auxiliary filtration for solar hot‑water systems.

• General Plumbing Installations

Used in systems that require both shut‑off control and inline particle filtration in one compact fitting.

• Installation Guidance

1. Confirm flow‑direction before installation; install with Y‑filter cavity pointing downward for optimal sediment collection.
2. Properly weld the PPR union end to matching PPR pipe. Do not apply excessive torque on brass body when tightening threaded side.
3. Keep sufficient operating space for bottom drain plug to facilitate future cleaning work.
4. After installation, perform pressure‑testing to verify zero‑leak performance.

• Routine Maintenance

1. Periodically flush out sediment by opening the bottom drain plug. Flush frequency depends on water quality.
2. If water flow declines remarkably, close valve, open drain port, take out stainless‑steel screen and rinse, reinstall screen before restarting system.
3. Inspect stem sealing for leakage after long‑time operation. Add food‑grade lubricant to valve‑stem only when necessary.
4. Do not disassemble packing for short‑term idle equipment. Keep the valve internally clean to avoid particle wear on sealing seats.

All Yunnl brass filter ball valves pass factory pressure‑tightness testing. This integrated Y‑strainer ball‑valve is widely supplied to plumbing distributors, HVAC installers and heating‑system integrators. Sample testing and bulk project orders are supported globally.

Yunnl PPR single‑union Y‑type filter ball valve combines brass shut‑off ball valve and built‑in Y‑strainer screen. Designed for PPR heating pipelines, it captures sediment and scale to protect underfloor‑heating manifolds and domestic plumbing. Featuring convenient bottom‑plug flushing, PN16 pressure rating, sizes DN25‑DN32, this integrated fitting reduces pipe joints and simplifies HVAC installation for residential and light‑commercial projects.
