Check Valves
Precision Engineered Check Valves
Shipham Valve Limited is a premier manufacturer of high-performance check valves—also known as non-return or clack valves—specifically designed for the global oil, gas, and petrochemical sectors. Our check valves are engineered to permit fluid flow in a single direction, effectively eliminating backflow and protecting sensitive upstream equipment.
By utilizing a dual-port design (inlet and outlet), our valves provide a self-actuating safety barrier that ensures process integrity without the need for external power or manual intervention.
Performance & Reliability
High-Efficiency Flow: Optimized internal geometries to ensure superior flow rates and minimal pressure drop.
Zero-Leakage Assurance: Every valve is hydro-tested to ensure a bubble-tight seal against backflow.
Environmental Resistance: Specialized metallurgy for exceptional performance in sour, wet, or corrosive media.
Safety Standards: Built to accommodate fire-safe requirements and emergency system integration.
Guaranteed Quality: Covered by our comprehensive 12-month industrial warranty.
Piston Check Valves
Protection for high-pressure systems. Our piston check valves utilize a spring-loaded cylindrical piston that reacts instantaneously to flow velocity. Designed for applications where flow direction changes rapidly or where high-pressure surges are common, the piston is lifted by forward pressure and driven back onto the seat by gravity and backflow to prevent reversal.
Size Range: 1/2″ – 16″
Pressure Classes: ASME 150# to 2500#
Swing Check Valves
Versatile, flow-sensitive isolation. Featuring a hinged internal disk, our swing check valves offer a low-resistance path for forward flow. The disk automatically swings closed the moment flow stops or reverses, providing a mechanical fail-safe. These valves are entirely self-automated, requiring no electrical or pneumatic actuation.
Size Range: 1/2″ – 36″
Pressure Classes: ASME 150# to 2500#
Material Engineering
Our check valves are forged and cast from premium materials to withstand extreme thermal and chemical stress:
Cast Steel: High-strength options for standard industrial service.
Forged Steel: Enhanced grain structure for high-pressure safety.
Stainless Steel: Superior corrosion resistance for offshore and chemical processing.
