Buy Flow Restrictors for RO Systems at Wholesale Prices – Romegamart

A small but powerful component , the flow restrictor plays a vital role in the performance of RO water purifiers. Without it , an RO membrane can lose up to 60% efficiency , leading to excess water wastage and poor purification. For RO technicians , service centers , distributors , and bulk buyers , investing in the right restrictors ensures both system longevity and consumer satisfaction.

At Romegamart , India’ s largest B2B marketplace for water purifier parts , you’ ll find a complete range of RO flow restrictors sourced from verified suppliers , available at bulk friendly wholesale rates.


What is a Flow Restrictor in RO Purifiers ?

A flow restrictor ( sometimes called a flow restrictor valve ) is designed to balance the water flow inside an RO purifier. It maintains the required back pressure on the RO membrane , allowing it to reject contaminants effectively while controlling wastewater output.

In simple words : without a flow restrictor , your RO system cannot work properly. That’ s why it’ s a mandatory spare part for every domestic water purifier.


Types of Flow Restrictors Available at Romegamart

We stock restrictors for all major domestic RO models. Each option is crafted from long lasting , food grade plastic for safe and long lasting use :

  • 450 Flow Restrictor – White Plastic
    Standard model for domestic RO purifiers.

  • FR 300 Flow Restrictor – White
    Compact and efficient , suited for small RO units.

  • 550 Flow Restrictor – Food Grade Plastic
    Ideal for slightly larger or heavy use systems.

  • 600 Flow Restrictor – Nanshe Shhitong Compatible
    Premium model with wide compatibility for advanced RO setups.

All models are listed with supplier details , specifications , and bulk pricing , making sourcing easier for B2B buyers.


Why is a Flow Restrictor Important ?

RO purifiers work by pushing water through a semi permeable membrane. A flow restrictor ensures :

  • Correct back pressure for efficient contaminant removal.

  • Controlled reject water flow , reducing wastage.

  • Consistent filtration performance over time.

  • Improved lifespan of the RO membrane , lowering service costs.

Technicians typically replace flow restrictors during routine maintenance , making them one of the most in demand RO spare parts.


Related RO Spare Parts You May Need

When working with flow restrictors , service providers often need other compatible spares :

  • TDS Meter to check water quality after installation.

  • RO Filters sediment , carbon , and micron filters for better performance.

  • RO Pipe for leak proof plumbing and smooth connections.

Romegamart ensures all these products are available under one roof , helping you streamline procurement.


FAQs – Flow Restrictors for RO Purifiers

Q1. What does a flow restrictor do in RO ?
It limits wastewater flow and creates back pressure on the membrane , ensuring efficient filtration.

Q2. What happens if an RO runs without a restrictor ?
The system wastes excess water , the membrane efficiency drops , and purification quality decreases.

Q3. How does flow restriction work ?
By narrowing water passage through an orifice or valve , a restrictor manages flow rate and pressure balance.

Q4. Are all flow restrictors the same ?
No. Choose based on your RO model ( 300 , 450 , 550 , 600 , and so on ) for best compatibility.

Q5. How often should flow restrictors be replaced ?
Typically every 1– 2 years , or during major servicing , depending on water quality and usage.
