Valves and manifolds are essential components used in industrial piping, fluid control systems and instrumentation to regulate, isolate or redirect the flow of fluids or gases. They are commonly used in applications requiring pressure monitoring, flow control and maintenance of process systems.
They allow connection to multiple devices such as pressure transmitters and pressure gauges. As manifolds combine multiple valves into a single block, this reduces system complexity, simplify isolation and venting of instruments for service and calibration, resulting in reducing the need for extra piping, fittings and labour. Manifolds are made from corrosion-resistant materials like stainless steel for harsh environments.
Manifolds combine multiple valves (e.g. isolation, vent, equalizing) into a single compact block. Each valve body, typically made from durable materials like stainless steel, monel, inconel etc. houses the needle and other internal components including the bonnet, which covers the stem assembly.
The needle is operated manually via a handwheel allowing for the controlled movement of the needle in and out of the seat to regulate flow. A locknut ensures the valve remains securely set once adjusted. Packing around the stem provides a seal to prevent leaks and inlet / outlet ports enable fluids to enter and exit the valve.
