Retailer, Exporter, Wholesaler · Mumbai, Maharashtra, India
At Delta Enterprise, we specialize in the supply of high-quality industrial components including Iron & Steel products, Welding Consumables, Valves & Valve Parts, Industrial Tools, Fasteners, and Sealing Solutions.
With years of industry experience, we’ve built a strong reputation for reliability, competitive pricing, and exceptional product quality. Our diverse product portfolio caters to multiple industries — from oil & gas and water treatment to construction, fabrication, and mechanical maintenance.
Check valves, also known as non-return valves, enable flow in one direction while automatically preventing backflow. These self-acting valves rely on gravity, spring, or flow pressure to close their seat quickly after fluid reversal, avoiding system damage or water hammer. Available in swing, lift, spring, and dual-disc designs, they are suitable for a wide range of media including water, oil, gas, and chemicals. Constructed from cast iron, ductile iron, stainless steel, and brass, Delta Enterprise’s check valves are ideal for pipeline protection, pump discharge lines, and compressor stations. We offer full-size, spring-assisted Y-pattern, wafer, and flanged variants—with pressure ratings from PN10 to PN40. Our solutions serve industries such as oil & gas, water treatment, petrochemical, and process plants.
Product Description
Our check valves comply with API, ISO, BS, and ANSI standards. Sizes range from ½″ to 24″, with class ratings from 150# to 600#. We offer variants like swing check, spring check (Y-pattern), and piston/lift check for vertical applications. Optional accessories include dashpots, lever weights, vacuum breakers, and flanged, threaded, or buttweld ends. Every valve is hydro- and pneumatic-tested before dispatch. Packaged securely for export and domestic delivery, Delta Enterprise ensures full traceability with batch reports and material certificates. With competitive pricing, fast turnaround, and reliable logistics across India and abroad, we meet complex industrial requirements seamlessly.
