Stable low flow
The restrictor is selected around the operating point to provide repeatable flow without complex adjustment.
Available supply
Flow Restrictors and Gas-Line Accessories
Components are selected by inlet pressure, target flow, gas, pressure drop and connection. The porous structure helps stabilize laminar flow, reduce pulsation and operate with no particle shedding.
Available configuration range
Porous restrictors, gas resistances and compact fittings for stable sampling, gas delivery and instrument-line protection.
- Material
- 316L stainless steel
- Flow range
- Selected by inlet pressure and gas
- Interface
- 1/4 in VCR, thread or fitting
Technical specifications
Gas-line flow control
Clean construction
For high-purity gases, material, surface finish, leak tightness and no particle shedding are confirmed.
Fitting integration
The restrictor can be a standalone part or an integrated element inside a fitting, panel or gas cabinet.
