Plastic Equilibrium Float Valves for Cold Water Services are important parts used in water
storage tanks and plumbing applications. They play an important role in controlling the water
flow. The valves also manage water supply by automatically adjusting the flow according to
water level, thus avoiding overflow. The efficiency of these valves depends upon proper
functioning of the float mechanism, continuous flow of water, and durability due to which they
can be reused several times.
BIS Certification for Plastic Equilibrium Float Valves as per IS 12234:2021 is important because
it helps to check that the product satisfies all the necessary requirements such as flow
performance, size, strength of materials used in manufacturing, leakage resistance, and
durability. BIS Certification of these products not only checks their efficiency but also helps to
achieve consistency in different batches.
What is IS 12234:2021?
This is the Indian Standard for plastic equilibrium float valves used in cold water service
systems. It specifies performance and quality requirements to ensure proper water level control
in tanks and storage systems. As per BIS, these float valves are:
- Assessed for pressure and flow handling capability
- Evaluated for material strength
- Checked for design accuracy
- Tested for leakage resistance
Who can apply for BIS Certification under IS 12234:2021?
BIS authorisation under IS 12234:2021 is required for businesses involved in manufacturing,
importing, or supplying plastic equilibrium float valves for cold water services in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the products are covered under QCO.
- Foreign Manufacturers - Need certification to export the plastic float control valve to
India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified float valves.
Performance Testing Parameters for Plastic Equilibrium Float
Valves
To ensure reliable water level control in storage tanks and plumbing systems, BIS has defined
