Check Valves

Reliable Check Valve Suppliers

Oilway is one of the notable check valve manufacturers in India. We supply reliable, robust check valves designed to meet the strictest of international standards. Each check valve either has a disc or ball that opens in one direction during fluid flow. The ball or disc is seated perfectly when the fluid flow stops, thereby closing the valve automatically. Combining our traditional roots with innovative practices, we create check valves that perform functions more smartly. We are committed and dedicated to working towards a new era of check valves that fulfil even the most challenging orders.

What is your expert advice regarding the replacement of old check valves and check valve maintenance?
Our valve experts suggest that preventive maintenance is the best way to extend the durability of your check valves. All check valves must be tested once a year and replaced every three to five years.
What is the purpose of a check valve?
Check valves are otherwise known as one-way valves or non-return valves. Check valves are exclusively designed to permit only a uni-directional flow and prevent the reverse flow of media.
