Eco-Water Saving Faucet Flow Restrictor & Non-Return Check Valve Series
Optimize your residential water usage and stabilize flow rates with our premium shower and faucet flow control series, available at Atradesen.com. Crafted with a heavy-duty POM (polyoxymethylene/copolymer) plastic casing, a robust 304 stainless steel spring, and an EPDM high-grade sealing ring, these precision water restrictors provide high temperature resistance, durability, and corrosion-proof operation.
These energy-efficient flow valves are designed to be retrofitted inside standard G1/2" (4-point/4分) threaded shower lines, faucet aerators, or inner piping walls to control, limit, and smooth out standard municipal flow delivery.
Key Functions & System Protection
-
Constant Flow Rate: Engineered to provide a stabilized, pre-selected flow rate (ranging from 5 to 12 L/min) even under fluctuating water pressures, preventing excessive water consumption.
-
Anti-Scalding Pressure Stabilization: Reduces pressure shocks when multiple appliances (such as washing machines or other faucets) are used simultaneously, protecting users from sudden water temperature spikes.
-
Backflow Prevention: The integrated non-return check valve prevents cross-flow contamination and maintains single-direction pipeline pressure.
Available Styles Explained
Depending on your plumbing setup, select from our four high-performance configurations:
-
Built-in Non-Return Valve (14mm / 15mm): Features both a check valve (to stop backflow) and an integrated flow limiting restrictor.
-
Built-in Flow Restrictor (14mm): A specialized insert designed solely to limit standard flow rate.
-
Spacer Flow Restrictor (15mm): A gasket-style flat restrictor washer that drops directly into faucet and shower couplers.
-
Drip-Proof Washer (15mm): Provides an high-sealing compression washer action to stop dripping in faucet aerators (does not restrict flow rate).
-
G1/2" Thread Adapter (Male to Female): Standard 1/2" brass thread coupler housing designed to contain the 14mm/15mm inserts for external in-line installations.
⚠️ Size Selection & Clean Water Notice
Please review these specifications carefully to ensure compatibility:
-
Measure the Installation Port: Before purchasing, measure the internal diameter of your faucet aerator housing or shower hose joint. Choose the 14mm or 15mm insert style based on your measured dimensions.
-
Clean Water Requirement: These are high-precision micro-valves. They are only suitable for clean, filtered municipal tap water. Any particulate matter, sand, scale, or impurities in the water lines can clog the small flow channels.
-
Flow Rate Rating: The L/min flow rating is measured under standard municipal pressure of 3 bar (3kg/cm²). Flow rates will fluctuate slightly depending on your home's actual water pressure.
