Exporter of stainless steel wafer check valve wordlwide, View price list of ss316 check valve

Fit-Lok is one of the most trusted manufacturer and supplier of Stainless steel check valve in wide range of sizes, pressure rating and types. Primary function of CF8M Wafer Check Valve is to keep the flow of media such as oil, gas or water in one direction. Before purchasing these valves please make sure that you know the required pressure rating and size and connection required to fit. We keep ready stock of ss316 check valve in range of 3000 PSI to 20000 PSI. These valves make sure that pressure flow is in right directions especially when the pressure condition of media can reverse the flow.

Stainless steel swing check valve have superior corrosion resistence ability and can withstand a higher temperature range. These valves comes with O-ring seal which helps to secure these valves and minimizes leakage risk. We have established ourselves as trusted Stainless steel check valve manufacturer in India. These valves have to pass through more than 15 destructive and non-destructive tests to make sure that they will not fail in live conditions.

We are exporting AISI 304 spring check valve in USA, UAE, Malaysia and Spain, We are known for delivering before delivery timelines which makes us suitable choice for your application. We also keep ready stock of high pressure stainless steel check valve in standard sizes and pressure rating to immediate dispatch. Simple design and durable material of stainless steel foot valve makes it better choice in various application due to its minimum maintenance requirements and reduced costs.
