Product Description
NAI-LOK Alloy 625 (UNS N06625) 2 Valve Instrument Manifold 1/2" FNPT High Pressure for DP Transmitters & Gas Systems
The Nai-Lok Alloy 625 2 Valve Instrument Manifold is designed for high-pressure instrumentation systems, including differential pressure transmitters, flow measurement devices, and pressure monitoring equipment. Made from Alloy 625 (UNS N06625), it offers superior resistance to chlorides, seawater, acids, and aggressive chemicals, making it ideal for offshore, marine, and industrial applications.
The 2 valve configuration allows operators to safely isolate and equalize differential pressure transmitters during maintenance or calibration. Its 1/2" FNPT connection ensures easy integration with process instrumentation, while precision-machined valves provide leak-tight and reliable operation under high pressure.
Nai-Lok also manufactures instrumentation manifolds in various materials, including:
Stainless Steel: SS304, SS316, SS316L, SS904L
Duplex / Super Duplex: Duplex 2205, Super Duplex 2507
