Manufacturer, Supplier & Exporter of Bronze Check Valve
Bronze check valves (also called non‑return valves or one‑way valves) are vital components in fluid systems, preventing reverse flow and protecting pumps, compressors, and other equipment. Made from bronze alloy (commonly BS 1400 LG2 / ASTM B62 / IS 318 LTB2), these valves combine good corrosion resistance, strength, and reliability, making them especially suited for marine, water, HVAC, and light chemical service environments.
At Riddhi Siddhi Impex, we manufacture bronze check valves using high‑quality bronze alloy, ensuring consistent metallurgical properties and dimensional accuracy. Our production includes casting, machining, assembly, inspection, and testing under strict quality control procedures. We offer different forms of check valves—such as swing check, lift check, wafer check, and spring check—in sizes and pressure classes suited for domestic Indian infrastructure and industrial systems.
Our bronze check valves come in various end connection types, including flanged, wafer, and screwed (threaded) ends. Depending on application, we offer them in pressure ratings like PN10, PN16, or equivalent ANSI classes. The internal components such as the disc, hinge, seat, and spring (in spring check types) can have trims of stainless steel, bronze, or optional soft seat inserts (e.g. PTFE) for better sealing.
Riddhi Siddhi Impex is a trusted bronze check valve domestic supplier, servicing major metropolitan hubs like Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, and more. We maintain regional stocks or logistics tie‑ups to ensure rapid delivery in these cities. Our reach further extends to other industrial and emerging markets in India such as Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, and many more.
In addition, we supply to coastal, port, and shipbuilding centers such as Visakhapatnam, Kochi, Thiruvananthapuram, Mangalore, where bronze’s corrosion resistance to seawater is particularly advantageous. We also cater to textile / process / chemical clusters in Coimbatore, Madurai, Nashik, Kolhapur, Chandrapur, Akola, and industrial belts in Gujarat (e.g. Dahej, Ankleshwar, Navsari, Valsad, etc.). Our customers include water utilities, chemical plants, marine yards, and HVAC / pumping integrators..
