Instrumentation Valves & Manifold
Instrumentation valves and manifolds provide the isolation, flow control, and non-return protection needed across pressure and instrument lines. Needle valves offer fine throttling control for precise flow adjustment in high-pressure service, while ball valves give quick quarter-turn on/off isolation across a wide range of pressure classes and end connections, from threaded and compression tube versions through to multi-port 3-way and 4-way configurations. Check valves prevent reverse flow to protect upstream instruments and equipment, with cracking pressures selectable to suit the application. Compact panel and gauge valves mount directly at instrument panels for local isolation, and manifolds combine multiple valve functions into a single block to simplify installation around transmitters, gauges, and other instruments. Built from stainless steel bar stock, the range covers instrumentation, process, and utility lines from 1/8" through 2" and pressure classes from 3,000 psi through 15,000 psi.
