For over 15 years, we have been a trusted supplier of  instrument valve manifolds to wholesalers, distributors, and large contractors worldwide. Our mission is to solve your supply challenges and help expand your market share. Partner with Beyond Fluid to achieve lasting business success.

Leading Supplier of Instrument Valve Manifolds in China

Instrument valve manifolds are compact units used in industrial systems to control fluid flow for pressure, temperature, and flow measurements.
They connect to instruments such as pressure transmitters and gauges, enabling isolation, equalization, and venting.

Common types include:

  • 2-valve: For static pressure measurement
  • 3-valve: For differential pressure transmitters
  • 5-valve: Adds venting and calibration capabilities

These manifolds simplify piping, improve safety, and ensure accurate, reliable measurement in demanding applications.

Beyond Fluid manufactures high-quality instrument manifolds compatible with Swagelok systems.

Pressure vs. Temperature

This chart illustrates the pressure-temperature performance of materials used in instrumentation manifolds:

  • Alloy C-276: Excellent high-temperature capability; maintains up to 6000 psig around 450°F (232°C).
  • 316SS: Stable under moderate temperatures; pressure rating decreases above 600°F (316°C).
  • Alloy 400: Ideal for lower-temperature applications; pressure drops significantly above 400°F (204°C).

Proper material selection ensures safe, accurate, and reliable performance in high-pressure and high-temperature conditions.
