SHUANGLIN VALVE | Filter Ball Valve, DN15–DN50 (2-in-1 Shut-Off & Strainer)

Installing a shut-off valve and a strainer as separate components means two fittings, two sets of threads, and two potential leak points — for a function that often needs to happen at the same location anyway. SHUANGLIN VALVE's filter ball valve combines both into a single brass body, giving you quarter-turn shut-off and Y-strainer filtration in one fitting.

Two Functions, One Fitting

Downstream of the ball valve's shut-off mechanism, the same body houses a Y-strainer chamber with a removable mesh screen cap, positioned at the same angled orientation used in a standalone Y-strainer. Water passes through the strainer before continuing through the valve, catching sediment, scale, or debris in the same footprint where a shut-off point was already needed — commonly ahead of water meters, pumps, or appliances where both isolation and filtration are required at the same point in the line.

Fewer Joints, Simpler Installation

Combining these two functions into one component means one less threaded connection in the system compared to installing a separate ball valve and Y-strainer in series — which translates to one less potential leak point and a faster, more compact installation, particularly valuable in tight mechanical rooms or under-fixture spaces where lining up two separate fittings can be awkward. SHUANGLIN VALVE manufactures this filter ball valve in solid brass, rated to PN16, across the DN15 to DN50 size range, with female threaded connections and a blue quarter-turn handle.

Key Features

• Integrated ball valve and Y-strainer in a single brass body

• Removable strainer cap allows screen cleaning without disturbing the shut-off valve or surrounding pipework

• Quarter-turn handle for immediate, clear shut-off control

• Flow direction arrow marked on the body for correct installation

• Reduces the number of joints compared to installing separate valve and strainer components

Where It's Used

• Ahead of water meters, requiring both isolation and debris protection at the same point

• Appliance and fixture supply lines needing a combined shut-off and filter

• Pump suction or discharge points in space-constrained installations

• Retrofit projects where adding both functions separately isn't practical due to limited space

Frequently Asked Questions

Can the strainer screen be cleaned without shutting down the whole line? The ball valve should be closed first to isolate the section, after which the strainer end cap can be removed and the screen cleaned, then reinstalled — all without disconnecting the fitting from the pipeline.

Is this the same as buying a separate ball valve and Y-strainer? Functionally similar, but combined into one body with one fewer threaded joint than installing the two components separately in series — reducing potential leak points and simplifying installation, particularly in tight spaces.

Does the strainer affect the valve's shut-off performance? No, the two functions operate independently within the shared body — the ball valve provides full shut-off regardless of the strainer's condition, and the strainer filters flow whenever the valve is open.
