Swing Check Non Return Valve Manufacturer – CI, SS & Brass Models India
Swing check non return valves (NRVs) are essential in plumbing, process, and fire systems to allow unidirectional flow and prevent backflow. As one of the most popular check valve types, the swing design uses a hinged disc that closes automatically with reverse flow pressure. In India, swing check NRVs are available in cast iron, ductile iron, stainless steel, and brass, manufactured to ISI, API, and international standards.
What is a Swing Check Non Return Valve?
It’s a mechanical valve that prevents backflow by using a swinging disc that opens under forward flow and shuts with reverse pressure. It does not require manual operation or actuator, making it a passive safety device.

FAQs – Swing Check Non Return Valves
Q1. What’s the difference between a swing check and lift check valve?
Swing type has a hinged disc that swings open, while lift type has a vertically moving disc that lifts off the seat.
Q2. Can swing check valves be used vertically?
Only if the flow is upward and valve design permits it. Most are suited for horizontal installation.
Q3. Do they create water hammer?
Improperly sized or fast-closing discs can cause water hammer. Use cushioned or silent NRVs if needed.
Q4. Which is better: brass or stainless steel swing NRV?
Brass is economical and corrosion-resistant for domestic use. SS is better for aggressive or industrial fluids.
Q5. What sizes are readily available?
Standard sizes range from 15mm to 300mm in most material variants.
