Component Specifications

Definition
A gas valve is a mechanical device designed to control the flow of gas within an accumulator system, typically used to regulate pressure, isolate sections, or enable maintenance. It ensures safe and efficient operation by managing gas entry, exit, and pressure levels, often incorporating features like shut-off, regulation, and relief functions to prevent over-pressurization and leaks.
Working Principle
The gas valve operates by using a movable element (such as a ball, gate, or diaphragm) that adjusts the flow path in response to manual, pneumatic, or electronic control signals. In accumulators, it modulates gas flow to maintain desired pressure levels, with some valves including safety mechanisms that automatically close or vent gas if pressure exceeds set limits.
Materials
Common materials include stainless steel (e.g., AISI 316 for corrosion resistance), brass (for general use), or carbon steel, with seals made from nitrile rubber, PTFE, or Viton to ensure gas-tight operation and durability under varying pressures and temperatures.
Technical Parameters
  • Actuation Manual, pneumatic, or electric
  • Connection Type NPT or flange
  • Pressure Rating Up to 300 psi
  • Temperature Range -20°C to 150°C
  • Flow Coefficient (Cv) Varies by model
Standards
ISO 5211, DIN 3352
