NOSHOK Distribution Manifolds and Valve Assemblies are engineered to consolidate complex multi-instrument piping hookups into compact, leak-free factory assemblies. Distribution Manifolds connect multiple instruments—such as analog pressure gauges, smart pressure transmitters, and mechanical switches—to a single diaphragm seal or process connection. By engineering low internal cavity volumes, these manifolds minimize temperature-induced volumetric fluid expansion error and eliminate multiple threaded fittings. NOSHOK Direct Connect Assemblies further close-couple differential pressure transmitters directly to orifice flange taps, completely eliminating impulse lines, stainless steel tubing, brackets, and gauge line errors. Rated for working pressures up to 10,000 psi with 100% helium leak testing and NACE MR0175 compliance.

Technical Specifications & Integration Guide
Configure customized distribution manifolds and direct connect valve assemblies to streamline multi-instrument mounting, protect cathodic pipeline integrity, and eliminate measurement errors.
Assembly Part Number Architecture
Distribution manifolds significantly reduce the total fill fluid volume required when pairing multiple instruments with a diaphragm seal, avoiding high temperature measurement error.
Stabilized connectors absorb bending moments and radial pipe vibrations, protecting threaded fittings from stress fatigue.
Dielectric kits isolate pipeline cathodic protection currents from electronic instrumentation transmitters and indicators.
NOSHOK Distribution Manifolds and Valve Assemblies are engineered to provide integrated, turn-key solutions for process piping and measurement instrumentation. In conventional installations, mounting a pressure gauge, transmitter, and switch to a single line requires assembling multiple tees, nipples, and isolation valves—creating extensive leak paths, increasing structural overhang vibration, and accumulating excessive internal fill volume that distorts measurement accuracy.
NOSHOK Distribution Manifolds resolve these challenges by machining multi-port distribution galleries into a single solid block. This low-volume design ensures that when coupled to diaphragm seals, the minimal fill fluid volume minimizes temperature-induced drift. Furthermore, NOSHOK Direct Connect Assemblies mount differential pressure flow transmitters directly to orifice taps, eliminating impulse lines and preventing gauge line error caused by ambient temperature gradients, gas condensation, or liquid vaporization.
Multi-instrument distribution for 2 to 5 instruments from a single process tapping or diaphragm seal
Ultra-low cavity fill volume reduces thermal expansion error on diaphragm seal fluid fills
Eliminates up to 80% of threaded joints and field pipe connections compared to traditional branch piping
Direct Connect Assemblies include stabilized connectors with integral block valves to eliminate vibrational shear stress
100% helium leak tested to 1 × 10⁻⁴ ml/s ensuring absolute hermetic performance under extreme industrial conditions
Distribution Manifolds are especially advantageous when coupled to diaphragm seals: because temperature changes cause seal fluid expansion, minimizing the cavity volume in the distribution block preserves total system accuracy.
Direct Connect Assemblies with Stabilized Connectors shift cantilever and vibrational stress loads away from the NPT pipe threads, providing rigid mechanical stability and eliminating catastrophic piping fatigue failure.
Dielectric Kits eliminate metal-to-metal electrical conduction between process pipeline and measurement electronics, preserving cathodic protection.
Futbol flange adapters provide easy field maintenance and interchangeability without disassembling welded process piping.
Complete turn-key assemblies are factory filled, calibrated, and helium tested by ATH Performance.
